1991 GMC S15 Jimmy Problems

Driveability Problems Due to Internal Distributor Fault

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.

Check Engine Light and Erratic Gauge Operation

The electrical contacts in the ignition switch may fail and result in erratic instrument panel gauge operation or illumination of the Check Engine Light. A failed ignition switch will require replacement.

Coolant Leak From Heater Core

The heater core under the right side of the dashboard may leak engine coolant which can puddle on the passenger front floor. The loss of coolant may cause an engine overheating condition. Our technicians tell us that removal of the dash board is necessary to replace the heater on these vehicles.

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.
