When I run my heater or a/c after about 15 minutes I hear a high pitched fan noise. Almost as if it is trying to cool the motor. However, even after I have shut the heater r a/c off it continues to run. Even after I have shut the car off for several hours when I start the car up it is still running. It is only after about 15 to 20 minutes of not running the heater or a/c and driving that it kicks off. I have also noticed that if I switch from low to high heat or a/c too quickly it bogs down while idling. Not sure what could be going on.
