Three problems related to tail light switch have been reported for the 2004 Chevrolet Trailblazer. The most recently reported issues are listed below.
Currently own a 2004 chevy Trailblazer that was repaired due to NHTSA action # ea04021. Very soon after the repair to the rear tail lights was completed, rear brake lights failed on both sides simultaneously. Dealer indicates that the left rear brake circuit board has "melted. ".
Well have a rear tail light bulb stop working and broke the outer shell. And my sun roof stopped working and isn't completely sealed when it rains water leaks from the top!!.
Back hatch and window will only open occasionally if I'm lucky. Tail lights went out once and I was able to get the hatch open to fix it. They are out again and I can't get the hatch to open now. I have been replacing head lamps about every 8 to 10 months. Head lights are now going off for no apparent reason while I'm driving at night. I can flip on the brights and then wait a few minutes and flip back to low beams, sometimes this works sometimes it doesn't. The dome lights will not come on and stay on after I turn it off. Half of the dash lights for the radio are out, sometimes they will come on if I tap them. The feature that lets you turn the vehicle off and the radio will continue to play and the windows will still roll down as long as you don't open the door, is not working. Both O2 sensors are out and have been for a long time. I purchased this SUV brand new from a chevy dealer. I have paid it off and kept up all of the general maintenance on it. When I took it in to get these issues fixed I was told it would be over $2500. 00 to fix and that did not include labor. This SUV is a lemon, if I was in a position to trade it in or buy a new one I would, and I would not be getting another chevy. I have never been notified of any recalls. I only found out about the electrical recalls on the turn signals and tail lights because a friend had heard about them and suggested a website to check. I'm calling the dealer today to see if I can get these issues taken care of. Another reason I will not be buying chevy again.
