Two problems related to underhood wiring have been reported for the 2004 Chevrolet Trailblazer. The most recently reported issues are listed below.
I have many electrical issues with my 04 Trailblazer from my window lights on the drivers door and the passenger door. I have had my radio replaced because it melted one of my cds. My head lights work when they feel like it same with the rear wiper. It has stalled out in traffic on me. I have also heard that in most 2000 to 2006 Trailblazers the reason for the electrical problems is because water is running down the passenger side door into the dash and hitting one of the main wiring harnesses causing it to have many electrical issues. I heard this from someone who has an 06 Trailblazer that just had it a replaced for $700. 00 to fix and was told that it will just have to be replaced in a few more years because they cant fix the problem.
I parked and turned off my car and it burst into flames. I had absolutely no warning, no warning light came on and I had no problems with the car at all until the fire.
