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