the problem is when the baffles move from heat to ac and vent to defrost they either get stuck or the controllerr is bo. this system is built to fail safe in the defrost mode. Thus ac comes from Defrost vents. Apparently it is wide spred with Ford and Chev. As it is in my 2001 Ford F-350, My opinion To much Matel Toy company plastic and cheep parts we pay considerable money for from the dealers. 1) check your controller at the dash probably vacume 2) check the acutator at the butterfly flapper. Some vehicles are easier than others.....
