Known Problems

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

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.

The intake manifold gasket can develop external engine oil leaks. The intake manifold will need to be removed and the gaskets replaced to correct this issue.

Corrosion at the fuel tank to body harness may cause the Check Engine Light to illuminate or a crank no start condition. This corrosion issue is most commonly caused by a water leak inside the vehicle. Any damaged wiring or connectors will require replacement.

The mass air flow or crankshaft position sensor may fail causing the engine to intermittently stall. It may be necessary for the engine to cool down before it will restart.

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 display on the heater and AC control panel may become dim or go completely blank. Our technicians tell us the control panel must be replaced to correct this fault.

The serpentine belt tensioner pulley may wear out. Our technicians tell us that in order to get a new pulley from General Motors you must purchase a complete belt tensioner assembly.

 

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.

One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.

The auto level ride compressor may fail causing the rear of the vehicle to ride to high or too low.

Do to a low or erratic voltage condition, the fuel gauge needle may "jump" around and become stuck on the back side of the "stop" below the "empty" indicator. This does not mean the gauge is broken. If the gauge cover is removed and the needle is gently moved back around to the correct side of the pin, the gauge will again function normally. When the needle is moved back to the correct position, the electrical problem that caused the needle to jump in the first place must be corrected or the needle may jump around again. The most common problems that cause this condition are a weak battery or corrosion on the battery cable ends.

The anti-lock brake (ABS) pressure modulator valve assembly may fail internally causing the ABS light to illuminate.

The mass air flow or crankshaft position sensor may fail causing the engine to stall intermittently. Proper diagnoses will be necessary to determine the cause of any stalling condition.
