Six problems related to dash wiring have been reported for the 1996 GMC Jimmy. The most recently reported issues are listed below.
My Jimmy caught on fire. The fire department stated that it was a defect in the fuse box system. It was a total loss. I am saddened to think that this happened. Just because the vehicle was 10 years old, doesn't mean that it should catch on fire. I had been christmas shopping and lost it all.
Wiring harness that leads to the lumbar support in the front passenger seat caught on fire.
While idling vehicle caught on fire due to an electrical short under the dash.
No summary listed for above vehicle.
Speedometer sticks when driving with lights on for 15 minutes or more. Dash gets very hot unless dash lights are turned to lowest setting. When dash lights are turned to the lowest setting, the speedometer begins to work normally.
The wiring haress under the dash to the power seat had burned together therefor shorting out the battery and the alternator which caused intermittent stalling. Nlm.
