It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.

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.

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 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.

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

The water pump may develop a coolant leak resulting in an engine overheating condition.

 

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.

I have 3 windows that will not go up or down although the drivers side works fine

The fuel pump can fail causing the engine to stall and not restart. Our technicians highly recommend to replace your fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.

The rubber section of an automatic transmission cooler line may develop a fluid leak . In some cases the leaking section of hose can be replaced. In others, the complete cooler line must be replaced to correct this concern.

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

I'll turn up the temp on the dual control to get heat, and/or the defroster to blow warmer air. All I get is cool air that makes for an uncomfortable ride and slower defrost. I did replace the blower motor in the summer, could this have caused the problem by not hooking something up correctly?

The EGR tube may develop an engine vacuum leak causing the engine to run lean. The Check Engine Light may or may not illuminate.
