2004 GMC Canyon Electrical system Problems

“The Gmc passlock lockout feature is a pain in the rear of nearly every car/truck owner having this feature. Today, for the umpteenth time, my vehicle would not start when I tried to start it up after fueling. My truck was stuck at the gas pumps, obstructing other patrons waiting to gas up. I sat waiting for about 5 minutes and tried starting it again, while getting dirty looks from other people waiting to gas up. Of, course it didn't start because I hadn't waited the requisite 10 minutes. …”

“After reading a post from the 116 affected Gmc Canyon owners I have the exact same problem. Last month june 2019 while driving home from work my AC just quit working (hot weather in sacramento), no matter what speed it was on 1 through 4. I also smelt a burning smell. Today while driving my truck to the realer to get it analyzed I hit a bump and the blower started working again on speed 4. Bob from john l sullivan chevy just called to confirm the diagnosis...the connector that connects to the blower was melted and the resister was burnt.”

“I just read a jalopnik article on a recall of the g3 hummer and the question why the Canyon/colorado was not included. A few years back the blower fan quit working on low settings. I found a tech tip that suggested I replace the fan resistor, which I did. I remember when I replaced it there was brown marks on the resistor and plug at the electrical connectors. While I did not suffer a fire like some others, this is a real problem with these rigs. Thought you should know...”

The brake light out was a safety concern for tailgaters. So I took to mark christopher Gmc dealer, ontario ca for repair because of two same recalls on the vehicle plus transmission oil change. Original estimation of cost was 305. …”

“My 2004 Gmc Canyon has, for the past year, quit starting due to anti theft passlock system installed on truck. I have on two separate occasions thus far been involved in an emergency situation that could have been further prevented but the anti theft passlock stopped me from starting the vehicle. This specifically is a widespread problem that GM is aware of and has made no recall to date on the issue. There are safety and emergency situations being caused by this defect. Please research and assist any way possible.”
