Thanks to both of you guys. I think I'm on to something here, so will do the heater hose bypass this weekend and see what happens.
September 15:
So here I am now in mid September, and in Austin it is HOT. 93 today and humid as heck. I did the heater hose bypass this past weekend, and it did help. Thing is, it is fine now as long as you are driving at normal speeds, but if you slow down for an extended time, or in stop and go traffic, then the air starts warming up. My thought process says the condenser is not funtioning properly, maybe clogged coil? Any way to cure this without replacing the condenser? Am I correct in suspecting the condenser?
