when you say no air comes out the vents, do you mean the fan is on and blowing but no air comes out or is the fan not coming on? Do you mean no air blowing out of the vents, or defrost and heater too? Need more info
the fan will not come on at all, but I can feel heat as I drive the car for a distance. as I have stated the blower motor has been replaced. The defrost take a while put it does eventually defrost the wind shield. can you give me some suggestions on this problem?
