Four problems related to underhood wiring have been reported for the 2002 Chevrolet Trailblazer. The most recently reported issues are listed below.
In June 2010 the overhead dvd player quit working and the bose in-dash stereo systems began to intermittently work and not work. In may 2012 the windshield wipers would sometimes not turn on and at times in operation would stop operating mid way. At the same time, the bright lights sometimes would not come on. Moving the steering column up and down would allow the brights to operate, but in most cases they don't work at all. The heat & a/c fan motor only works on high speed as well leaving the other speeds inoperative. It seems there may be an electrical issue in the steering column and I'm not sure if the stereo and dvd player would be somehow connected with that portion of the wiring harness. I contacted Chevrolet and they say there are no open recalls for our VIN number.
The first time I had problems was about a month ago when the check engine light came on. I brought the vehicle in to lynch service department and it was taken cared of that same day. On 10/25/2002 my car completely shut down and it would not start for me at all. I had my vehicle towed to gillespie chevy dealer service department and as of today 10/29/2002 my vehicle is still there . I was told that it is an electrical problem but that was all I was told. Now I'm just sitting and waiting. Dt.
