1990 Chevrolet S10 Blazer Problems

Heater Core Under Right Side of Dashboard May Leak Engine Coolant

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.

Power Window Motors May Fail From Overheating

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.

Replace Fuel Filter Every 30,000 to Prevent Fuel Pump Failure

The fuel pump may fail causing the engine to stall and not restart. Our technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.
