1990 Chevrolet S10 Blazer Problems
The transmission output shaft seal may leak transmission fluid. On 2WD models, this leak can cause the transmission mount to become oil soaked, which will require replacement of the mount along with the leak repair. On 4WD models, if this seal leaks, the fluid will leak into the transfer case, causing it to become overfull.
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 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.
The Anti-lock brake system (ABS) control unit may fail internally causing the ABS warning light to illuminate.
