GM Blower Motor Resistor Troubleshooting | 2002-2009 Chevy Trailblazer GMC Envoy or similar 

You did not show how to pull that plug out of the blower motor!!!!!!!!!!!!!! You put the camera down... No!!!!!!!!! I have spent thirty minutes trying to figure out how to unplug it. Come on!!!!!!!!

This helped out so much I'm doing a drive across Canada and I'm 4000km away from home and about 200km from a mechanic who can speak English and it's currently 7pm so everything is closed, (I'm also car camping so this honestly saved my life/ sanity) thank you for this ❤

My plug wouldn’t stay tight to the resistor, so I cut up a plastic zip tie and jammed 4 pieces in it, now it all works 100% I am amazed. Thank you very much.

This just happened with my 2007 trailblazer. A/C stopped blowing. I messed with the harness and sure enough, the fan came back on. Zip tied it, good to go. However, I see and smell burnt plastic on one of the wires, so I'll replace the harness just to be on the safe side. Thank you so much for making this video!

Just bought the wife an '06 Trailblazer. The blower works on 1-4, but not on 5. I'll get up under there and see if a zip tie will fix it! Thanks so much for posting this! I've been wrenching on cars for 41 years now (since I was 16) and cheap fixes are still OK by me! Also, it would appear that your wife's Trailblazer is missing the plastic kick panel under the glove box, unless you removed it and didn't show that part.

What is the name of the wiring harness I have a 2003 trailblazer and mines is kinda burned

Those plugs plug into the xm radio controller don't hurt nothing if you don't have it

I changed my resistor and my passenger door will not work, electronically. It turning signal does. Will not lock or window won't roll down

I've got a 2007 trailblazer, my heat wouldn't really work through my vents, but it would work on dash, now it's not working at all. Please, help if you can.

Saved me money.. exactly the problem I had, it's to cold not to have heat. Thank you

Hey boss just wanted you to know. That this is the first video on this subject and problem that offered an every man look at the situation .you saved me money and time and made a subscriber out of me. I wish you the best of luck with your channel and look forward to the next video thank you

Thank you for taking the time to share your experience. Your video was very helpful.

Just bought an 04 Envoy a couple days ago and the heat sometimes works and sometimes not. You just helped me to trouble shoot it and narrow it down.

My 04 has the same exact issue this helped me a lot. Thank you saved a lot of time and stress

Thanks for this help, I look forward to more of your posts...GMC ENVOY XUV owner since 04

Thank you, I had to bang on my Resistor and heat , ac came on. Thanks for this wonderful video.

Thank you so much. This happened to my blazer and you saved me a ton of money and time.

You are the Man! Thanks so much for the advice, this fixed it for my wife and now she is Happy 😁

Thank you so much!! You should be proud you have helped so many people!! I got this 2004 GMC Envoy "cash car" And I am having to fix issues myself. so your video helped me save some $ , I was about buy new everything!! i live in TX-- we gotta have AC in our cars. Any way,,, Thanks & be Blessed

You may never see this, but THANK YOU. I live in Fort Worth, Texas….OMG the summers are HOT. I can’t live with no A/C. I love Zip ties…hahaha. I was tickled. My husband died from cancer a few years ago and so I’m Ms Fixit on his Chevy Silverado. It’s getting old but I don’t care. I love that truck because he loved that truck. And yes I do do the mechanical work whenever I can. My past jobs working at a defense contractors in their mechanical & electrical assembly positions gave me a good start for auto mechanic work. And people like you give me the ability to get it done without needing a mechanic I can no longer afford. Thank you again. I’m pretty sure I have a similar problem because if I tap on it, it blows and I replaced the blower motor last year. So if it’s not a loose pin connector, then I’m just gonna go ahead and buy that connector
