My 96 Millenia is blowing out hot air. I had the unit recharged and it will blow cold for the first 10-15 minutes, then it starts getting warm. The air is gets hotter then the outside air so i believe it is straight engine air.I have triedmessing with the controls andthe relays but nothing seems to help.needless to say i have to keep all the vents turned off because after you have been in the car for a few hot air is blowing from everywhere.
please help
