The Anti-lock brake system (ABS) control unit may fail internally causing the ABS warning light to illuminate.
The distributor may develop internal faults. This can cause a rough running engine or stalling condition and the Check Engine Light may or may not illuminate. The distributor should be overhauled or replaced to correct this concern.
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.
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. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.
A fluid leak may develop from the transmission output shaft seal. This leak may cause the transmission mount to become oil soaked and require replacement of the mount along with the leak repair.
The power door locks may stop working in one or more doors due to a failed actuator. Replacement of the failed actuator should correct this concern.
Our technicians highly recommend that the transmission is serviced every 30,000 miles to avoid problems and maintain optimal operating order.
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 electrical contacts in the ignition switch may fail and result in erratic instrument panel gauge operation or illumination of the Check Engine Light . A failed ignition switch will require replacement.
An engine oil leak may develop from the distributor shaft o-ring seal.
Brake fluid can become dirty and may cause problems in the brake system ; it should be flushed every 60,000 miles.
This engine may leak oil from the valve cover gasket .
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.
A coolant leak may develop from the water pump . This can result in an engine overheating condition. A leaking water pump will require replacement.
