Two problems related to trunk wiring have been reported for the 2002 Chevrolet Trailblazer. The most recently reported issues are listed below.
For 2 years now I have had problems with both of my tail lights not operating dealer replaced circuit boards 2x and that still has not solved problem.
Wiring harness burned up. Caused damage to control panel, dash, computer system. Entire vehicle gutted to replace wiring. A door panel was broken in process. Several rattles now exist. We were told there was no way of knowing if electrical problem would occur again. Gm agreed for repurchase. However, they delayed procedure so that 0% financing can not apply. Also wanted us to pay out of pocket, buy back amount said we would be reimburced, but would not put it in writing. Dt.
