Have you checked for vacuum leaks to the HVAC system?

If you are lucky, you may hear a whistling sound if there is a leak. Under the dash, you will see vacuum hoses. Just make sure none are broken or disconnected. Also, there is a supply hose from the engine. Make sure it is good.

That is nearly always caused by a bad blower motor resister. It's located under the dash on the passenger side, in the blower housing and next to the blower motor.

Procedure for what?

The mode doors are operated by an electric actuator that controls air direction. There can be a problem with the door jamming, the actuator itself or the control head that controls it.

Hi lkpowell,

Check for low coolant level in radiator. Symptom indicates a leak in the heater core and coolant level should be low.

Hi there,

Thank you for the donation,

These cars have a problem with the heater control unit, if the slider on the dash feels stiff, dose not move all the way or is very loose, the control cable or the control is faulty, check the heater tap to see if it is opening or closing, if it is moving the heater tap will be faulty.
