Problem Reports

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.

On vehicles with intermittent windshield wipers, the wiper motor circuit board may fail and cause the wipers to stop working at times. Replacing the circuit board should resolve the issue. Some vehicles were recalled for this problem and some were not. You will need to check with your local dealer to find out if a specific vehicle was included.

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

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.

Vehicles using the enhanced vortec V6 engine may be hard to start run poorly and/or use to much fuel due to a fuel leak inside the intake manifold plenum. Commonly this is caused by a leaking fuel pressure regulator or fuel line. The fuel system will need to be pressurized with the upper intake manifold removed in order to determine the exact cause of the leak. Removing the "tuning valve" from the upper intake can allow for limited visual inspection without removing the upper intake manifold.

The alternator may fail, causing a "no charge" condition. An internal bearing may also fail and cause an abnormal noise. If the vehicle is driven too long with a failed bearing, the alternator may stop turning, which can cause the serpentine belt to break or the engine to stall and not turn over.

The EGR valve may stick open causing a rough idle and the Check Engine Light light to illuminate. Our technicians tell us that a piece of carbon may become stuck in the valve causing this problem. Cleaning the valve will usually correct this condition, in some rare cases the valve will need to be replaced.

The distributor may develop internal faults. This can cause a rough running engine or stalling condition, the Check Engine Light may or may not illuminate. Our technicians tell us that the distributor should be overhauled or replaced to correct this concern.
