1993 GMC Sonoma Problems

Brakes -- Verified

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

Heating & Air Conditioning -- Verified

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.

Drive Train -- Verified

Our technicians highly recommend that the transmission is serviced every 30,000 miles to avoid problems and maintain optimal operating order.

Electrical & Lights -- Verified

The power door locks may stop working in one or more doors due to a failed actuator. Replacement of the failed actuator should correct this concern.

Electrical & Lights -- Verified

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.
