Known Problems

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.

One or more power window switch may fail. The affected window may work intermittently before failing completely.

The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.

A coolant leak may develop from the water pump. The engine may overheat as a result of the coolant loss. A leaking water pump should be replaced.

 

The high pressure power steering hose will commonly leak fluid; it should be replaced.

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

The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine  with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

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

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.

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

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

The fuel pump may fail causing engine to stall and not restart.

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.
