Air compressor ice cold but blowing really hot air through car vents
1999 grand marquis air compressor ice cold but
blows nothing but heat out the vents what could it
Listen VERY CAREFULLY while you move the lever from off, to floor, to defrost, to cabin. You should be able to hear the vent door move if it is working correctly, going from one input and output to the other.
Temp blend door or motor not working, u may also have a vacuum leak or bad blend switch
