ok thanks. The 39 should be after the car is warmed up and moving for say a mile? Want to go and test and see whats up. Even moving it really doesn't feel cold.

the temp of the air coming out the vent should be 39*..this is going down the road.
think of refrigeration this way, it doesn't make anything cold, it removes heat..the condensing coil (in the grill) is a heat exchanger, if its really hot out side or no air can take away the heat, your a/c will suck.
sounds like the high side switch on some on these cars may be bad...but 134 isn't as forgiving as the old r-12..
