Left turn signal not working, been chasing this problem , this , is a confirmed fix!!! Thank you

The video was spot on! The only difficult part I encountered was removing the signal relay. It was more difficult to loosen and pull out than I expected.

Glad I found this video. I had a problem with my Silverado in which the right signal would work. But the left wouldn't. So even with the hazard lights only the right would flash. I installed this the same day I saw the video and it worked perfectly. Saved me big bills that mechanics were gonna charge me. Thank you!!

Thanks for a great video - worked for our 2005 Yukon. I'm teaching my son that there are a lot of things you can fix yourself. In the old days, you just started taking things apart -with KZfaq it's way easier!

I would like to add that this was very helpful to me with a problem I had with a 2004 Chevrolet Silverado. The flashers on the Silverado would come on and off sporadically. Until I replaced the Directional Relay. Thanks for the great starting point.

Thank you for this video SteveO, my 03 Tahoe was experiencing the exact symptoms you described . Local dealership wanted 85 to diagnose and 110 an hour for labor, (whaaat!) Went to the local part shop and pickup up the relay for 70 bucks and less than 20 minutes in my labor and good as new. I especially want to say thank you because the wife won't be hounding me to fix it anymore!!

THank you very much for this video! 1) It confirmed what was causing my turn signal problem; 2) I made the entire repair in less time than it would have taken just to DRIVE to the repair shop. 3) I saved hundreds of dollars in parts & labor. (part was only $40 on amazon)

This fix worked perfectly! Problem symptom: When I put my left turn signal on, both right and left signal lights flashed (just like when you turn the hazards on). Changing this part fixed the problem. It took a total of 10 minutes to complete the repair. Thanks for posting this video! Saved me $100-$150 in repair costs.

Worked to fix my 1999 Chevy Silverado. Was just a different relay part than the one in the video. I used a "EP29 Electronic Flasher" and fixed my turn signals no problem. Thanks for the video!

great video. I have a 04 Silverado with no right turn signal coming out of the pigtail for a trailer. This helped me tremendously. Btw, how can 23 people dislike this video? Straight,short, to the point! I have watched other car videos that were 10-20 minutes long and never said anything that was useful.

I watched this video not sure if I could tackle this or not but I saw it wasn't as daunting as I thought it would be . The only suggest I could make after trying to pull the switch out for 30 minutes in my 2005 GMC Sierra with my fingers is skip the congested area and use water pump pliers .....

I had a slightly different problem when I hit the brakes, the left turn signal indicator (dash) would light up and stay solid. My left hand turn signal on the drivers side mirror would also light up when i hit the brakes. I bought this part and viola, ITS FIXED!!!! I have to cancel my appointment at the mechanic now!!! I've been trying to fix this myself for a month and finally found this video! THANK YOU THANK YOU THANK YOU!!! Awesome video and straight to the point. Took me less than 10 minutes. 2003 Yukon Denali 6.0 gas. I got part on Amazon for about $50. IDK who gave you thumbs down but they suck at life:)

Thanks for making this video! I was having the same issues with my Yukon, and didn't know where to start trouble shooting. Well done.

Just changed the ignition switch on my 2001 Chevy 2500HD Silverado and now my turn signals work when they feel like it. (started one week after) Thanks for the excellent video, in spite of your camera.

It is more commonly referred to as a TURN SIGNAL FLASHER at your local auto parts store. Part Number LM487 at Autozone or Part Number FC563 at Advance or O'Reilly. It will cost a bit more, but you won't have to wait on shipping. Great video though. P.S. In many cases, the flasher can be repaired. (It's just corrosion.)

My 2004 Chevy Suburbn was having problems with turn signals intermittantly. They would stop flashing when the brake pedal was pressed, and resume blinking after releasing the brake pedal. Also found that cruise control would sometimes disengage if I used a turn signal. I just replaced the flasher repay per this video and problem solved! Thanks for the video Steve O!

Thanks Steve O. With this video I was able to swap out the flasher relay in about 20 mins. It took longer to find one at a local parts store than to complete the job. So far so good. My 4 ways came on when I used the left turn signal in my 2003 Tahoe

83.00 dollars at autozone whent to the junk yard "accidentally fell in to my pocket works like a charm. great video helped me allot.

45 "thumbs down" for this video? What the hell? Haters gonna hate. Great video Steve O. Fixed my wife's 2004 Suburban in 10 minutes. She's happy. Saved $$$. Win-win. Keep up the great work.

Thanks, dude! Your video saved me some money.

Thank you. It literally took me 5 minutes to replace the relay from start to finish. And I'm a lawyer--not a mechanic. Great video.

The video is simple and gets to the point. The only change I would make, before putting the trim panels back on, make sure the turn signals work. Knowing Murphy's law, if I put all the panels back on, it won't work, On the other hand, if the signals still don't work, would would a person do next? I have a 2001 suburban , the four way flasher works ok but the turn signals stopped working. I'll order the relay and replace it. Thanks, well done.

When I use either turn signal, the clicking won’t stop. It’s driving me crazy. Thanks dude!

Excellent video. My driver side turn signals, front and back, were both flashing as if they were burned out. Replaced the bulbs. Same thing. Then i came across this video and it solved my problem. Thank you.

Not sure if it will be a permanent fix, but I just opened the plastic case on the relay and cleaned the contacts with some contact cleaner and reinstalled. Fixed the problem without an $80 part!

My turn signals would just turn on and not blink. This fixed the problem! Thanks

This worked great. My truck lights worked fine but my trailer lights went haywire. The left signal light worked OK but when I switched to the left both lights flashed. When the brakes where applied only the right light came on. Replacing the flasher module fixed it all.

Thanks you I tried everything know left turn signal only Wright turn signal I ordered same part number your post hope it work

Thanks!! Been driving around with a left turn signal that would flash like crazy or just didn't flash at all. Thought it was a larger issue with the electrical, but this solved the problem and only took about 10 minutes to replace.

Husband just replaced mine🎉 Thank u very much your video was very helpful ❤

Steve thanks a lot for the video it was very useful. .... mine is doing the same left turning doesn't work only the right. .... now I know how to fix it , thanks Steve. ...

Thanks for the video, I love posting videos of things that can help other people, especially when I can't find one on You Tube. You are the only one I found that is really addressing the issue of my 2002 too 2006 Silverado. I recently started upgrading my truck to LEDs and have to change the electronic lighting control module. (Blinker relay) I found mine for $30 brand-new in package, "delivered" on Amazon from the manufacturer (Novita). It's part number LM 487 The video was definitely helpful. Thanks again

Ur the bomb Steve O, took me longer to run to NAPA to get the part than installing it. 30 BUCKS for the part & a little elbow grease!

It worked yahoo i got mine at autozone $43.99 dealership $97 bucks took me 15 minutes 04 Tahoe 4x4 same set up as 03 in Video Thanks a million

Thank you so much for this video. I was told when I had my back up camera installed that the top was glued. But, with your video, I kept trying, and the trip came out w/o a problem. Also, the relay was an issue, but you said it might be, so I kept at it, and all went perfectly. I literally do not think I could have done it w/o this video. Thanks!

Thanks for the video because I'm having this problem now with my 2005 Chevy Tahoe

Thanks SO much! Worked perfectly!! My problem was that the blinker on my '04 Yukon XL was just clicking really fast when turned on, and the blinker indicator was not lighting up. Such an easy fix following your instructions! Excellent job on this video!

This fixed the problem. Issue was right signal wouldn't come on. I installed it myself took a few minutes. I'm a lady with acrylic nails and I didn't break one. Just follow the video. Part at pep boys was 79 bucks. Amazon with prime 2 day delivery was 48. I have a 03 Tahoe.

The right turn signal in my 2003 Suburban reliably works but the left turn signal only works sometimes. Sometimes I need to turn the left signal on and off 3 times before they work, sometimes it takes more than that. Also sometimes I need to turn the steering wheel (at a stop at an intersection) a good bit to the left before they will work and stay flashing.

Thank you very much for sharing, awesome video. In may case your video helped me locate the turn signal flasher in my 2006 GMC Sierra. I replaced all of the incandescent running lights with LEDs and the turn signal went hyper. I found a direct replacement (plug and play) Turn Signal Flasher on eBay. I do not have the part yet. I will update you after I install the part.

I initially was only looking for the location but ended up watching the whole video. I'll have to get a flasher relay and put it in. 2 questions though. 1. Wouldn't you recommend people testing the turn signals before putting the panels back on? 2. What in the world are GM engineers smoking that makes them want to locate items that require removing half the dash to gain access to them?

our problem was no turn signal on both rear, side lamp and fronts flashed twice as fast. checked flashers, wiring grounds , bulbs ,all the above. no cure of problem. I work in a chevy dealership, they were scratching their heads. I work in the body shop. not a wiring problem fixer. I had several left over wiring harnesses from tail lamp replacements. plugged one in. bingo, left turn worked . tried the right one bingo, it worked. only problem, wasn't correct wiring as it had no side lamp. so I figured it was from the harness back and that left the sockets as wiring looked good. started to check sockets, from the top. it looked not correct down inside, metal connector contact points looked irregular. pried with a small straight screwdriver and pried gently around until looked like other prong. then looked at bulb. it had the 2 wires on each side. held the wire down at the loose end and gently pried a small rise in the wire, reinstalled bulb and plugged wiring back it. . bingo, worked like new. did same to other side and it fixed it also. hope this works for you because this is very frustrating when you try everything and still no cure.

I just wanted to say Thank you Steve O for this video. It helped me out. I fixed my 2003 Tahoe that had this problem.

worked on my 05 chevy avalanche, that had a left blinker/fast blinker some times. only took about 7 minutes and some cussing and swearing to get out the actual old module. thanks a bunch!

Thank you for your simple and helpful video just got mine done on my 2005 avalanche ✅

Thank you so much for this video. I was able to replace the relay and now both of my turn signal work properly.

Thanks for posting your video. You saved me a trip to the mechanic and lots of $$. I followed your instructions and it worked! Thanks again bro

Good video. I'm chasing an intermittent blinker problem. Luckily, the dash is easy to get into on these trucks.

Thanks for the help man just changed mine ,solved my blinker problem...right side wouldn't work ...easy fix

I have replaced both my front and rear turn signals with LEDs and I have a Novita LM579 flasher equipped. My problem is when my headlights are on, both turn signal indicators light up and the turn signals stay on the high setting and dont respond when I go to use them or even the hazards. However, everything works when my headlights are off. Possibly a defective flasher? My truck is a 2003 2500HD.

On 2004 Yukon there is a ground wire behind driver side rear tire that goes from the chassis to up near the gas filler cap area. If it is broke rear blinkers wont work along with other strange electrical problems.

Thanks for taking the time, real informative fixed my problem!

Saved me from buying the multi function steering column stalk. Thank you for the help.

Did anyone have difficulty removing the Relay. I can't get enough leverage on the part to pull it out. Does anyone know what's holding it in? Is there a tab need to release?

I accidentally was messing with the ground of the signal light plug with a metal picking tool while the turn signal was on and forgot to turn it off before all of that. Now it won't blink or flash. Did I static shocked and burnt the turn signal relay?

my 1990 chevy truck turn signals dont flash on the dash but do outside, will this fix that?

My Silverado turns on the brights when signaling a right turn, would this relay fix my truck

Quick question.... so on my 06 tahoe, i replaced the tail lights with LED taillights. all lights work, running lights, brake lights, reverse, right turn signal, just no LEFT turn signal. i replaced the relay switch but to no avail. what could the issue be?

Thank u much ill be doing this in the snow we are having today and will be upgrading my rear tail lights to LED Today

Great video. Hi steve I have a question. I have a 2004 chevy tahoe I installed after market Led Tail lights. And at night I'm unable to drive the car because with the headlights being on. My tail lights stay off. I don't get it. If I hit the turn signal the signals work but they blink fast. If I hit the break light it works fine If I go reverse my led bulbs work fine. But when the car is on at night and the headlights are on. My tail lights stay off. Do you think replacing the Flasher Module can help solve this issue.

Thinking mine is the flasher I’ve already had to replace it but now the signal on the dash is sped up and the bulbs still work in the rear as running lights but got no brake light or signal on the left side

On my 2001 Silverao my signals don't work when my lights are on nighttime. You thid relay is bad? All lights on the side seem okay?

If there was ever a recall this would be the one.

Man!! I just replaced mines. What a job when you don't have proper tools 😅😅😅

Thanks for the video. Changed mine out today and fixed the problem.

I actually needed this help because I'm having the same problem. Thanks.

My 99 escalade sounds as if my blinkers or hazards are on but they are not. When i hit the brakes the sound of the blinkers stop clicking. And when i put my right turn signal on sometimes it wont work. And also the back right tail light, the plastic on the light bult almost acts like it gets melted a little bit to where that hole tail light assembly stops working until i clean it out and change the bulb... would the relay cause this?

Thank you for sharing, great video.

I have a 2016 gmc sierra sle i have this code U0077 i have aftermarket light everything was working fine for the past 2 years with the LED lights yesterday i have a Right Rear Turn Failure could this fix my issues i try cleaning the ground when the truck is on everything is perfect except turning right and my break

Great video. Thank you for taking the time to make it.

It’s fun watching videos like this, in my opinion. It’s good to know how to fix older parts in older cars even though my car is a 2015 Buick Encore, which doesn’t use any clicker for the turn signals. It has electronic turn signals on it which are cool. But mechanical turn signals are cool too, in my opinion. I think most GM vehicles, older and newer models, are cool in their own ways.

Awesome video. Answered all my questions. Easy fix. Thanks

Great vid. Thanks. Ps I drive only chevy now. but im just so frustrated with the electrical ive had 2 chev vans unfixable wireing shorts.

Good video I took a gamble on buying the part and it worked much appreciated !!!

I don’t have turn signals at all , or brake lights but my flashers work and my running day lights any pointers u can give me?

How did you replace the actual time in the OD dash meter? I have a suburban too and I would like to know.

This helped me tremendously! Thanks

is this the same for my 2007 newer body style? but with the 5 pin? instead of the 10... because i installed LED tail lights w/ the resistors and they still hyper flash.. somone answer please.

Great video. I have a 2006 GMC Sierra that has a problem. Whenever I'm driving at night, and turn on my right blinker, the brights come on. Never does it when I turn on the left blinker. And never does it during the day. It doesn't do it all the time. But will do it several times a night. Any idea if replacing the relay will fix this?

my 2002 savanna doesn't look like that under the dash. Can't find that part

Great tutorial and a real time saver

Great job with the video all with one hand.

Worked perfectly. Thanks for sharing.

My signals work and I can hear them ticking on the dash...... just no green Arrows (lights) showing on the instrument panel. Is this the fix for that? Thanks

Problem found. No right turn signal power to pigtail for trailer. Side of dash fuse panel has left trailer fuse, right trailer fuse (trl) and then seperate fuses for the tail lights on the truck. 4 fuses! 1 was burned out. 10amp. Hope this helps someone.

I have a 2000 Chevy Silverado. Turn signals work fine...until I put on the brakes. Then, its like the 4 way flasher was utilized. Not sure if its the turn signal, brakes, or a relay

Glad I found this. Thank you so much for posting.

I recover my truck it was stolen turning signals don’t work and my hazard emergency button no working any ideas of what do I need to do

I have a 2005 GMC Sierra which seems to work, but when I turn on the right signal it flashes the right turn signal, but it also flashes the brake lights too and if I have the cruse control on it disengages that too. The dealership who replaced the hydro boost last year said it was not a connected issue but that is when it all started. Would the replacement of this part solve these issues?

Thank you so much, this was my exact problem...

2006 Suburban... When my turn signals are activated (independently and 4 way), if i push my brake, the rear lights flash instead of the amber turn signal light. The turn signal just stays illuminated. I have narrowed it down to a directional relay, faulty multi switch or faulty turn signal/ cruise control switch. Do you think this relay is the culprit? Bulbs and fuses are new

My 2003 Suburban Flex 5.3 is flashing the hazards when I hit the right turn signal. Left signal works fine. This is something that has come and gone for a while, but it's getting more common. I've also noticed sometimes if I get the hazards, if I flip to the left turn and flip back the right will work. Should I start with this relay or look elsewhere?? Thanks for the video! I'm going to ask this as well. I just called a NAPA and they cross the 10383320 with LM455 and that is $31. The 10383321 crosses with LM487 and is about $75. He says the more expensive one is for LED lights, which I don't believe I have. It also appears the $30 relay is the 3/6 option and the $75 relay is the 2/4 option. From my research the 3/6 is for towing a trailer, which I do on occasion, but have never noticed any issues with what I have, of course...maybe that's the cause of the failures....thoughts???

Thank u Sir, I had no idea where it was.

I have a 1999 Chevy Tahoe with no turn signals, all fuses are good and all other lights are working including hazards and break lights. Does the 1999 Tahoe have the same directional relay as you have shown on the video?

any advice on how to fix a blinker that won't turn off? the lights don't go off but the sound clicker won't stop!

Thanks for the video! Worked great!

I don't know if it would be the same thing but my husbands truck is a 2000 gmc sonoma, and when u turn on the right turn signal it blows out the fuse so the left goes out and the brake lights!

Maybe you can help me with my problem... When I turn left my blinker flash rapidly but when I turn right they are normal. I figured the issue was with my truck needing new bulbs so I replaced the front and back on the driver side and the issue still occurred. The tricky part is, when I turn my emergency flashers on, all lights work normally....

Could a bad turn signal relay cause the brake lights to stay on? I'm having to same issue with the turn signals making the 4-ways come on, and when I'm braking and using my turn signals they won't flash on the dash,

thanx man I fix mine thanx to this video
