1991 GMC S15 Jimmy Problems

The distributor may develop internal faults. This can cause a rough running engine or stalling condition, the Check Engine Light may or may not illuminate. Our technicians tell us that the distributor should be overhauled or replaced to correct this concern.

A door window may move slowly or stop in mid travel due to a failing power window motor. The affected window may start working again after the motor cools off. Replacing the faulty window motor will commonly correct this concern.

The Anti-lock brake system (ABS) control unit may fail internally causing the ABS warning light to illuminate.

1991 GMC S15 Jimmy Reviews

this truck has been great, bought mine with 75000 miles on it last november. i have had to put a new exhaust system because the catalytic converter went bad but besides that i love this truck, this is a mean little truck and it can handle just about anything

My 1991 S15 Jimmy has been great for me, i have experienced some of the common problems like the power window motors going bad or the heater core leaking coolant onto the front passenger side of the floor. But besides these minor problems this truck has been nothing less than great for me.
