dash a/c goes to defrost under load
2015 windsport 34f, on long hill climbs my a/c changes from vent to defrost.comes back again when I let off throttle for a few secs. I have experienced this withholder chysler minivans and it was a lack of vacuum to a/c control head under load. I found my windsport has a vacuum cannister and it seems to hold vacuum,no obvious leaks found. has anyone else had this issue?
