Wow. This is the video that nearly escaped me. Just as I too was about to spend $200-$300, I searched KZfaq one last time. Thank goodness. I and my 2002 Trailblazer thank you so very much!!

Just wanted to thank you for posting this video. I have a 2002 Envoy that had that exact same problem. The control module is no longer available individually to purchase for my vehicle. The mechanic wanted to charge me $300.00 for putting on new wiper motor which includes the module. I went in this morning and took the module out and cleaned it myself as you suggested instead and it works perfectly. You just saved me $300.00 plus the cost of the new part ($166.00) plus tax. Thank you for sharing. Roger

Just got to witness my wife's wipers work on all speeds for the first time after following your video. Thanks a lot OP.

Hi, Ran across your video and thought...hmmm! Did this process on my 02 TB w/144k. Works great!! Thank you for your time to instruct us!

I FINALLY got around to doing this today on my '02 Bravada (5 years later! (Identical setup as a Trailblazer, no Antenna on Bravada's though, lol) Absolutely nice and smooth wiper operation now, I also fixed a clogged washer nozzle since i was all up in it! 😀 Thanks for the perfect video!! Incase anyone else has a clogged nozzle all i did was soak the nozzle in vinegar for a while, then sprayed through it with an air compressor! Boom, like new again!

I know that this a 4 year old video, but it saved me some money and downtime on my wife's 02' TrailBlazer. Once apart and on my folding work table, (did the work in the driveway under the pines) all I did was remove the gear cover from the motor assembly, wiped the excess grease that had spilled over from the worm gear with a paper towel. The contacts were cleaned off using some Mass Air Sensor spray on a paper towel and wiped off. Reassembled to the point of the wiper arms (painted a matte black and let dry overnight in the house) and this morning put them on, checked the operation throughout the entire range, removed the painter's tape from the windshield and that was it. Thank you for posting this fix.

Hello FishingandRacing, NICE video and thank you for post. I used it to replace my washer nozzles that are under the cowling. Had a broken one that was squirting strait up! Cheers! Mr .P

SON YOU ARE A LIFE SAVER.....I WAS ACTUALLY GOING TO GET A NEW WIPER MOTOR FRIDAY.......IF I WERE CLOSE TO YOU I WOULD GIVE YOU A KISS.!!!! THEY WORK GREAT......SUCH A SIMPLE FIX BUT I AND MANY OTHER HAD NO IDEA WHAT WAS THE PROBLEM.....THANKS ALOT.....

Thank you for the video. Have been pricing new motors when I ran accross your video. After watching, I just tried it on my Trailblazer, and it worked great.

Was quite easy to do, wipers work great now. Just be careful with the plastic on the motor, work it slow by the plug with a screwdriver and you will be fine. The terminal tool I bought was made in China, after fighting with it I got the first wiper off but it wrecked the puller. So the passenger side one i used a screwdriver to pry against the metal plate under the plastic shroud on the wiper end.. be gentle and work it around a little bit and it will pop right off.. easy peasy

Thank you. This was exactly my Envoy 2002 issue as well. Nice and smooth wipers now.

How did grease get there in the first place ?

Thank u brother for this video I did exactly what you said and it worked I saved 200 dollars thanks brother

What did you clean the inside of the motor with?

Thanks for the wiper problem. I cleaned up the extra off of the white gear and contacts and took care of the problem.

I tried the battery post removal idea...no worky...I ended up grabbing it with a pair of pliers and rocking it back and forth and it came off REALLY easy.

I did this today trying to fix my wipers that have completely failed. Sadly it did not fix the issue. I can hear one tick when I turn them on but they do not move at all. Thanks for posting this. At least I know what to do when I get the new motor.

My wipers just failed completely. I think a motor assembly replacement is going to happen after i check fuses and relays. Thanks for posting the video so i know how to take it out and the terminal tool .

Thank you for the video! It helped me get the wiper motor replaced in under 2 hrs!

this worked perfectly for me! OK I used throttle body cleaner for the silver metal side and electric cleaner for the motherboard side.

Thanks for posting this. It worked great for my Pontiac Sunfire.

Thank you for posting!

Great vid. I was having the same issue and this fixed it. You just saved me a little money.

Excuse me, mines only work at the highest intensity level. What can I use yo clean them? Also, Do you think cleaning them will be the solution?

outstanding I was hesitant but a perfect fit, before I started project I disconnected the washer connection at passenger fender (top) after reinstall booth sprayers shoot over the windshield, it is in the exact spot and tight fit , there are no spray adjustable nozzles, I would understand one side but both, it's almost as too much pressure but the chatter and jerking problem is repaired, any thoughts on my new problem? thanks again Obie Juan kanobi

Thankyou very much for the video, i was able to fix it without a problem, this helped alot!

thanks for posting this

Works great! Thanks for the helpful video.

I'm gonna try this great video! I hope it'll fix it, mine works only on high.

Great video I posted a. Comment 3 years ago ,,, update the grease is there for a reason, I cleaned with brake cleaner though all, in sprayed white lithium grea and dryer, se, so the grease is a problem and a fix

Thanks for the video! I've had this same annoying problem for a few years. Now I can fix it! Did you use any type of adhesive/RTV on the housing when reassembling?

I took my 06 TB wiper out and the wiper assembly looked exactly like yours, but the electrical internals look completely different. The wheel has no contact to the board like yours, and the board is shaped differently and has like 100 tiny resistors and capacitors on it. When I look up the part it looks exactly like mine, can’t even find any like yours. Wish there was a known way to fix my style, cuz cleaning it did nothing and a replacement board is over 100 dollars. Smh

Ok awesome i need to do this.. I've been dealing with this exact problem for over 3 years on my '02 Bravada.. BUT isn't there a reason for some grease to be in there? Or where would it have came from?

Thank you!

good video thanks

Sweet, thanks!

What year is your trailblazer? I have a 2004 and my wipers will cut on and not stop. I have to pull the fuse.

Do you recommend using Electronic Cleaner for the inside of the motor?

good...

Good video on how to get the assembly out, but you are wrong about the grease. That is supposed to be in there.its contact grease. Very similar to what's on a horn ring.

Cording to my daughter as a little different of a problem

I bet you never had that problem in a Toyota but only in general motor cars 😒

wipers inop.

Why do all these videos say they will show you how to replace your back windshield wiper but none of them do there all the wiper arm it's super annoying and why don't they do a very good job of showing you that i don't understand why does he say u don't need to see what he's doing sounds so stupid wale up men show in detail and go over it a few times us women weren't taught this stuff so some of us this may even be thier first time working on a vehicle so why not go over stuff or at least do a good job of showing exactly what to do.
