Chevy Colorado Electrical Issues

Asked by Kade Nov 16, 2017 at 08:11 PM about the 2005 Chevrolet Colorado Z71 LS Crew Cab RWD

Question type: Maintenance & Repair

I have a 2005 Chevy Colorado (2WD, Z71, Crew Cab) and have had electrical
issues for about a year now. I replaced my headlights with aftermarket
headlights in the Spring of 2015, which I believe is the biggest reason why
everything is acting up. Ever since then, different problems have been piling
up. Starting with my automatic driver side window, which hasn't been able to
go up since the end of 2015. At the same time, my ABS has been having
problems. The only time it acts up is when I back up first before putting it in
drive, and when I turn left or right. The sound turns on that the abs is activated
without pushing the breaks and once I push the breaks it starts to make the
truck drag to the right side, which leads me to believe its something on the
right bearing. If going slow, it stays on, if going faster (like 25+ mph) it doesn't
make the sound. The only time it stops is when I come to a complete stop and
if it has been making the sound for a while. The ABS Fault Traction warning
comes on my dashboard and about 50% of the time the Parking brake
warning turns on. Since then, I put my stock lights back on and had to change
the fuse that controlled the headlights. Other than that, nothing has changed.
I also have got these codes from my truck:
C0040
Right front wheel speed sensor circuit
C0221
Right front antilock brake system channel in release too long.
(Sorry for the long post, if anyone could help me out would be awesome.)
Thanks!

The window problem is unrelated to anything else The clue to your problems could be "when backing up" .. if your truck has drum brakes in the rear ( I'm not sure drum brakes were still around in 05 ) then backing up used to adjust the brake. I'm almost certain that all your problems stem from something loose in the brakes system

2005 Chevy Colorado has electrical issues. Change the fuse before you attempt a major expensive repair/replacement.

Not that this is of any help at this point, but I recently replaced my headlights with a HID kit (of questionable quality) on my 2007 Colorado. I almost immediately started having weird electrical issues that could not otherwise be explained. I had to take the kit back off to make the issues go away. Namely, was an ABS light error that would appear on startup, occasionally the anti-theft would also get triggered. On one occurrence all of my gauges dropped to zero and the vehicle reported low fuel. This only ever happened upon startup or shortly thereafter. Never, while actually driving. My only thought is that the questionable quality of the xentec, was back-feeding dirty power "Noise" back into the system, causing the issues.
