My 1999 Suburban is blowing warm air from the front vents and cold air in the rear vents when the A/C is on. It has plenty of freon. Any advice on how to cool down the front?
The car uses the same freon in the front as it does in the rear. If the rear a/c is working, you either have a plugged evaporator in the front unit, or perhaps a bad heater switch. Try switching the heater to hot and see if it blows even warmer air from the front vents. If so, the heater switch is working and then it sounds like a plugged evaporator or maybe a plugged orifice tube. That is a good place to start looking. Hope this helps.
I change orfice tub ,actuator blend door i move it manualy on one side is warm and to the other side hot but not cold ??? Any thing else i can do
