#127 of 292 2006 Chevy Trailblazer Electrical Short
Feb 16, 2010 (1:07 pm)
Monday the 15th started real sour for me. I've recently gone over 70K miles in my 06' Trailblazer Ext. Around 5 or 6 months ago I had it in the shop what I recall was a crankshaft sensor that went out. Everything has been riding just fine on the vehicle. We did take about 100 mile drive on Saturday and it sat in the garage all day Sunday and overnight. Monday morning the garage was full of smoke and smelled like something electrical was burning. I figured it was my garage heater and shut it off. As I went to get into the car the doors were all locked and none of the remotes were working. I manually unlocked with the key (who does this anymore??) and there was no power to the trailblazer. She wouldn't turn over, nothing, dead, and, it wouldn't give me my key back (although I hear this happens on a dead battery). I popped the hood and it was scorched inside. I had it towed over to the GM shop and am awaiting the word on what happened. I am concerned due to the fact the car was parked for over 24 hours and while sitting there something caused it to burn up. Any thoughts? GM Mechanics seemed puzzled.

What exactly was burned? The electrical harness? Or something else?

I also had to replace the camshaft position sensor which is a small device with a short wire that sits on the top of the motor. This is not active when the car is off. The only burn problem I have had is the small wire harness inside the headlights. It actually burned off the bakalite connector.I don't know when this happened as I discovered it when replacing a "failed" headlight bulb.

Okay, in regards to the electrical burning part. I was informed this morning that my Electronic Brake Control Module or EBCM shorted out and caught on fire. I was also informed "You're very luck sir because the fuel line runs about 4 inches below the EBCM and that could have burned your house down." I was told to file a claim with my insurance company since this was not a mechanical or parts failure but a freak electrical accident. $3000 dollar repair estimate. I'm not sure I want this POS back in my garage. I'm outside of warranty and I found a list of possible recalls in the future for grounding problems on the EBCM for multiple vehicles within the GM line.

Just wondering if you ever found out what the problem was, I am having the exact same problem.

The Electronic Brake Control Module shorted out and caught fire. GM replaced as a manufacturer defect although my insurance had to cover the initial repairs. Just yesterday I returned the Trailblazer to the shop due to the ABS / Stabilitrac lights coming on again. This was the same set of lights that came on the day before the EBCM burned up. They better figure this out and soon because it's the fifth time it's been in the shop since the original fire.

No, never heard a word or suggestion. Since it was so cold, I ended up unplugging the windows inside the right front door. Thought I was unplugging just that window but none work now. Since it's warming up outside, I need a proper fix. I just know it's going to cost an arm and a leg. Good luck.

I have had my Tb since Dec '03, my airbag light has been on almost since the beginning...the dealer replaced the instrument cluster at least twice, once on them and once on me....the light is still on...I just ignore it and live with it. While turning 164,500 miles, my 3rd gear clutch pistons began slipping...4500 rpms to do 40 mpg...solution...replace transmission ($3000.00 parts and labor). I need more light at night while doing daily night driving in Pennsylvania....so...QUESTION??? Dare I risk running HID's ? Will they fry my wiring? Will 8000's get me pulled over? R GE Nighthawks a better solution? Can I up grade my headlights to a new one'10 ? I need more light at night....HELP!! (hopefully my rebuilt tranny is a done deal)..thanks
