1991 Chevrolet S10 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 1991 Chevrolet S10

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

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.

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.
