No cold air coming from vents
My vents only let cold ac through when the car is cold after it warms up it goes to a mixture of mostly hot but a little cold can be felt. The rear seat vents blow cold air. The driver side vents don't blow any air at all any time. I check the temp controler unit in the dash with another one out of a car at work and it did nothing. Are the flaper motors bad or what? Have had this problem for a while can't seem to figure it out. Anyone else had this problem before? Thanks.
