Known Problems

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.

When the heater only works on high, the most common problem is a blower motor resistor. The correct repair is to replace it with a new resistor.

The Engine Control Module (ECM) can fail causing stalling, and engine and transmission drivability concerns.

The inside door handle may break causing the door not to open from the inside.

One or more of the power windows may stop working due to a failed window switch. Failed switches will require replacement.

If the ABS light on the instrument panel illuminates, our technicians recommend checking the brake lamps first. It could indicate that a brake light is not working or has burned out.

Timing gears may wear causing a mild to severe knocking noise from the front of the engine. Replacement of the timing gears is necessary.

The front struts may show signs of wear, or be excessively bouncy ride at freeway speeds. This may begin to occur at around 75,000 miles.

The steering may develop a clunk type noise from the upper intermediate steering shaft.  Our technicians tell us that you should check with your local GM dealer to find out what the latest repair is for this condition.

The outer tie rod ends on the steering linkage may wear causing excessive free play in the steering and uneven tire wear. If the worn tie rod ends are replaced, the wheel alignment should be checked and adjusted as necessary.

The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.

The spark plug wire rubber boots may get soaked with oil, causing a misfire or rough idle.

The catalytic converter may become plugged resulting in loss of engine power. General Motors has extended the catalytic convertor warranty on some models to 10 years or 120,000 miles. Please contact your local GM dealer to see if your vehicle is included.
