I watched and then followed your video instructions and was able to replace the blower control module on my husband’s truck. He has shoulder trouble so the job was on me. Thank you so much for your wonderful instructions. I am sure we saved some money by being able to replace it ourselves. By the way, I am a 68 year old grandmother so that lets you know just how good your video was. Thank you so much.

Perfect video! Helped us figure out our problem with our 2003 Yukon. Blower motor stayed on last night outta the blue when I came home and this morning the battery was dead. Your video was the first to pop up when I searched it on KZfaq. Was the perfect fix. Thank you! 👍👍

Thank you for these kinds of videos! Folks love fixing things themselves and knowledge is the greatest tool in the shop.

Thanks for the video. When my fan all of sudden turned on and wouldn't shut off in my 2005 Yukon SLE I figured it was the resistor / module. I replaced one in my Ford Escape a few years ago and new what I was in for. Your video made it easy and I had the entire project finshed in 35 minutes for under $65 with next day shipping from Amazon. Thanks for helping teach people how to do things for themselves!

Thank you bud. This was exactly what I was needing. I also appreciate the tip at the end, always helpful to have a reminder to not only throw money at the truck, but also look over things while you're in there. Thank you.

Just had to put one in my 05 2500 service truck today. That cover is flexible enough that I did not have to mess with that screw above the hump. I actually watched your channel yesturday to diagnose the problem. Saved me 105 today in my area.

Thanks! You saved the day. Easy repair. Left that 3rd bolt in place, and just moved the cover to the side...used the same color connectors you did for the wires...and I've got heat! Keep the videos coming, and thanks again.

Perfect diagnosis. Didn’t take too long to replace the module. Excellent instructions and walk thru… thank you!

Thank you very much, this was exactly the issue I was having with my Yukon XL Denali, and I did exactly what you said and was able to fix it myself. I took it to the experts to look at it first, and they said the part I cut out was the wrong part, and that it would cost me $400+ to replace it. I decided to keep going with your video, paid $60 for the part you mentioned, and fixed it myself! Thank you very much!

Just wanted to say a big thank you! I followed your instructions exactly and now it’s fixed! Very grateful for your video!

Thank you for this great video. 2004 Envoy replaced resistor with your help. Had to remove the glove box because my old frame doesn't bend that well. Tip: if you do remove the glove box, reinstall it before installing the bottom cover. Left cover screw was a bear as you said so loosely screwed in the right screw first then shoved the cover up in place as hard as I could and lo and behold, the left screw went right in. Again, thanks for a great video.

Thank you for the diagnosis and fix. I just found a really nice loaded ‘04 Tahoe that had been in storage for a few years and it only has 100k miles. It had this issue upon putting in a new battery and I was able to know what to do thanks to you. I was also able to negotiate the price down another $600 because of the existing problem. $178 in parts and it was fixed in 20 minutes. Also, you absolutely don’t have to remove the screw closest to the center console. Easy. Thanks again.

Thank you! I ordered the right part and installed it in just a few minutes, thanks to your video!!

Thank you so much for taking the time to make this video. This happened to my sisters car but thanks to you we were able to fix it. Summers are brutal in south Florida. You saved us a lot of misery. God bless you.

Awesome this worked perfectly and quickly for me. 2003 Chev Avalanche. I ordered the part on Rock Auto took 3 days to get here and finally have my heat working for winter !! Thanks so much!

This is the best damn auto repair site on the web, great host!!! Keep it up.

Thanks for the helpful video which included the OEM part number. My husband appreciated your video and was able to handle the repair himself on his 2006 Chevy Silverado 2500HD.

Went to replace the mod, ended up finding a mouse nest under the cover! He had started chewing on the wires. Replaced it anyway with your help. Thanks man.

What's up Tim. I replaced my module today, first time. Quick tip to offer you on that pesky cover bolt. If you just loosen that inside bolt the cover will come down and swing out of the way with plenty of room to access and replace the module. You don't have to completely remove the cover. Took me 20 minutes total to complete the job.

Hi Tim, I had to to this on my Suburban, it was good to see that I did it like a Professional would. I have had problems with butt connectors so I soldered and shrink wraped mine, but other than that it was the same, I left that screw out, in fact I threw the screw as far as i could, no rattles yet, after about 20,000 miles, so I am pretty sure it will be that way forever. Thanks, see ya next time.

Thank you sooo much!! Was exactly the issue I was having and it worked. Called the shop and they want 400 plus to fix it my son did it for me no labor charge and part was $40 at junk yard.

The good side of KZfaq. Thank you!

Best "Fan Stuck On" video that I've seen so far! Thanks!!

Thanks for the repair directions! I just finished just like you said thank you Parts at the dealership was about $90 2006 Silverado 2500! Thank you I did only have to take two black screws off and it did access the black modular!

Thank you. I'm going to give this a try on my 03 suburban. Woke up to a dead battery and when I charged it the front blower would not shut off so i had to pull the fuse. Video is straight to the point

Thanks man I just watched your video you made it look easy man it took me like 4 hours but I got it done! I’m not a mechanic just needed to save money

Fantastic vid, appreciate the time you put into these!

Thanks! Easy fix and you are correct, that 3rd screw is royal pain. No problem or noise from leaving it out.

Thanks car doctor u just gave me some more information about the issue I'm having with my chevy blazer with the a/c blower motor staying on after turning truck off.

I stuck the screw thru a piece of electrical tape and then down to the socket and that helped a bunch... Thanks for the video it got me Goin in bout an hour...

Great video! Exactly what I needed. No BS just a straight up fix. As someone else commented that third difficult screw just needs to be a little loose and the cover drops down out of the way enough to make this repair. The most difficult part was making sure I got the right part. Looks like a lot of “bootleg” parts out there. I stuck with GM. Thanks again!

I had a similar "pain in the butt screw" on my 98 Chevy. Nice tips here Tim and the process was well organized.

You made that look really easy there Tim which just means you're a skilled craftsman. Looks like that old module caught you off guard at the end of the video LOL. Have a good one and best wishes to you and your family.

Thank you for the help I needed in getting the correct part. I did not remove that screw on the left of the case. Just moved the housing to the left, which gave me room to work on the wires'.

Great help Tim. I took the fuse out until I could get time to change it out. Udaman !

Exact fix I needed for my 2006 Yukon XL blower fan. Thank you!

Appreciate this very impressed with your instructions,easy to follow.

thanks for the heads-up! Gonna send the link to this video to my brother in law, so he can get prepared for the failure!

My brother-in-law's vehicle just did this! Went driving last night and noticed the there was a slight breeze coming out of the vents. The truck was dead this morning. Glad to know it was this module and what needs to be done.

Thank you for this informative video. It described my problem and the fix. Thanks again.

Thanks Tim just pulled mine and am looking for a new one now

Thanks a lot. Ordered same AC Delco Part on Amazon and followed your video.

Thanks man I just had 2 change mine. This was very helpful.

I just loossened the screw you are talking about and let the cover lay on the floor. The cover lined up very easily and tightened right up.

Major help. Thanks for this video. Such a relief my problem is fixed.

Wish I had a tip for you tim....did this 2 years ago on 03 trailblazer was not fun. Thanks for the vid and have a nice holiday!!

Thanks, this video was perfect! Exactly what I was looking for. 🔥🔥🔥🔥

My 05 Chevy just did this... Took fuse out to keep blower off... This looks fairly straght forward.. Thanks for the tips... Even if I take it somewhere I know it's not that serious and shouldn't cost a fortune...

I appreciate the video! You saved me hundreds...👍

Thanks esp for the tip on socket awesome video well thought out.

great video, I followed it and it worked perfectly thank you so much for the valuable info

hi time I just changed the sway bar bushings in my 2003 trailblazer but the clunk continues I checked tight rod ends ball joints what else could it be

So I just did this on my 05 Yukon. Instead of cutting the old connector off the factory harness, I removed the pins from the factory plug and also removed the the three splice wires from the replacement plug. I then inserted the factory wires into the new plug and finshed the module install. I'd recommend this only after you fully inspect the factory wires to make sure they are not burnt or damaged in any way.

I`ve done this repair many times, and the thing that many other people with this same problem are unaware of, is that a lot of retailers are still selling the original style crappy modules with the 3-wire plug......nothing like repairing your vehicle with a prone failure part and finding out afterward there was an upgraded part available. This video should help many people from making that mistake, although I recently pulled a bad module from a vehicle that had the upgraded version with a 5-wire plug......but at least when it failed, the blower motor didn`t stay on all the time, it just quit working altogether.

Thanks this was a lot of help and the answer to my problem that I was having...

Now does that take care of the rear one too or is that just for the front mine in my back of my 2004 tahoe sticks of all the time

Thank you man, you are the coolest.

I get so much crap from my boss and other guys in the shop when I struggle with a stupid bolt. But at the end of the day they all understand, I hope lol. I'm sure this video will help someone out. Thanks for the video.

Thanks for sharing your knowledge to us !!

I have a 2003 Denali that just started doing this. I pulled the fuse now… going to get the part and try my hand! Thanks

Safari gmc 2004 van....high speed fan setting not working...have replaced resistor ac delco...vdo autozone fan.....all other speeds work..I understand that the high speed setting does not go thru the resistor ..so..any idea what's going on here? I have checked the frt hvac 30amp fuse under the hood...any idea is appreciated

I just pulled the fuse every time I turned the truck off for 4 years! Your idea is better. 😂

Have you seen this on buick century's? I have a customer with a 02 complaining about this issue, wondering if it's the same and how to verify its the module and not the selector?

Thank you for your video,I was so flustered and had a bad day trying to figure what's going on???.I can fix it now..,very greatfull

In FL these burn up all the time, I never had it stay on but i had them not work or it looses some speeds. I have the white module now, They made a black plastic updated module, that one only lasted 2 years before it melted the connector. I believe that the high heat, constant AC use and moisture from the evaporator shorts it out. Its just too extreme here , its not designed for this climate. The 40amp weird cartridge fuse under the hoods fuse box will stop the blower from running if it happens at a bad time. , Remove it to stop it. I have that same Crimper I wore it out. now it has blue grips :) ya snap on. Its easier to disconnect the power connector on the blower motor when you remove it. Tab and a turn. I think all I did for removal was the two screws on the lower dash cover and i had enough free play on a GMC truck with the console to sneak it out. Alot of trade in vehicles I drove had INOP blowers. Trade it in when the blower stops, no AC new car, lol $$ So far, 115k, 10 years, I am on 3 blower modules which includes the factory part. Oh, One time I replaced the blower motor too. Korean Delphi motor!

I have a 2006 silverado that this just started on but 2 days ago the thing that looks like a speaker and has something to do with the HVAC started making a noise as well. Do you think that these 2 issues are related?

Thank you very much for your information Sr. God bless you for ever🙏🏼👍👏🏻👏🏻👏🏻👏🏻👏🏻

Is this the same for 2000 GMC Yukon new resistor was added one I plugged in to blowe fan kept running mines has black/white wire orange and black wire

Excellent video, thank you. Good tips at the end.👍

Good vid, no BS very helpful 👍👍

My problem is the fan on the rear AC unit on my Yukon keeps running. I put a switch on it to turn it off. Is there a module for the rear fan or does the one under the dash do both?

Awsome video and worked like a charm thanks for the help!!!

Does that module control the rear blower motor also? My 04 yukon the rear one is staying on

When it comes to removing the housing cover, remove the two far right retaining screws, and leave the third in place. The cover unit is flexible, allowing it to be moved out of the way. This presented no issues for myself in changing the module, nor damaged my cover. Just a consideration.

Thanks for the video! Very informative and helpful! Now I need to replace my module! I just learned of this issue with my 07 Silverado. The control was at first not working on 1but ok on 2 then it eventually quit working on anything but 5 and then I discovered it not shutting off, then I ended up killing the battery. I got it to shut off and talked to my brother for a little while. Went back to cab, then yep, blasting away. So I'll need to yank the fuse under the hood and I may as well replace battery ( factory battery believe it or not) but I'll try recharging to get it home. It's only 1/2 block away. So yep. I'll get her home and then fix it when I can.

Great video! Much needed help!

My truck has a constant got to the fan high. Like there's a short or a relay stuck. My module has a relay built into it as soon as I plug it in it engaged the relay. I only had high. I cut the wire now I have all but high. Is there another relay pressing to the module itself

Worked great! Thanks a lot sir.

Thank you, it worked like a charm!!

Is the module and a resister the same think?

Mikita angle driver for a drill works good. Thanks for the help

Excellent video! Thank you

I have a 2005 Chevy Malibu if the key is off and ac switch is off the blower motor turns on by itself...I have to remove the relay if not it drains the battery?

Why does my harness have so many more wires than yours? I have a red, orange, black, green, purple, yellow, and a peach color. All in that order. What should I do with the extra wires? I'm not sure what they are. I have a 2004 Tahoe.

What a great video, thanks.

Replaced the modual because blower didn't work. Replacing it got it working again, but.....now it won't shut off with the new one in. Thoughts please.

Very good vid helped me out alot

I have a 2001 yukon and the heat goes on for about 10 mins and then starts blowing cool air would this be the same fix. I have a 2002 gmc yukon danali and the blower stays on when I take the key out so I'm gonna change the module on that truck. But just wondering about the 2001 yukon and the heat. Thanks

Just watched you video... going to order the part and attempt this myself. I'm not very skilled at this kind of work... but I don't have the money right now to pay someone to do it. I'll let you know if I'm successful.

Does the control module have to be the updated version? I ordered the exact same one that is in it now which is the old one you show in this video. Replaced blower also and it still stays on when vehicle is shut off

Thank you for you help that’s all I need it

To remove the cover. I took the two screws out that I could get to. For the one closest to the center consul I just left that one loose enough to pull the black plastic cover down far enough to work on the control module. It did not take long at all I didn’t break anything everything came apart and went back together vary nicely and fast

This just happened to me. Thank you so much !!!!

Thank you sir! Once this new one is installed does it need to be reprogrammed or reset to work rite?

Great video!!!! right to the point and clear video. # chevycountry

man u are awesome thank you so much!

Thank you so much, After watching your video it narrowed down the problem with my Hummer H2. It was exactly what you said it was and I bought the Part online for $26. Of course this is after pulling my entire dashboard apart to get to the Climate control unit.lol.

Would this also apply to the Chevy Monte Carlo w-body?

I tried this on 2004 avalanche and the fan wont turn on. I tried to reset it, but didn't work.

I kinda have a similar issue, I turned on my rear ac and it won't go off, constant AC full blast, but when the key is off it turns off.. selector dosent work, when I change it to heat it dosent work just constant full blast AC
