If you get bored and venture out to north Jersey, I can take a look. Hook up gauges and see what's going on. Pm me if interested, I am about 8 miles from GWB

Sounds like the heater is heating up once the engine gets warm. Make sure the heater valve is closed. You can see if the heater hoses are hot.

The causes for your issue could be too little freon or the system is overcharged or the expansion valve is bad. The average system has both a high and low compressor cut out. You will know if you are undercharged by seeing bubbles in the sight glass of the receiver dryer. You won't see them if you are overcharged, but a high side gauge will indicate too much pressure by overcharging or by the bad expansion valve.

The most common problem is loss of freon and being undercharged as a result, but John will know when he connects the gauges.

Quick update. I don't think it an ac problem. Because when I flip on the ac after driving for a while (first time turning on the ac) it only blows hot. So that would rule out the theory that the ac fails after it runs for a while. Also the heater hoses are hot even when idling. So my heat vents/flaps must be slightly open. Anyone disagree with the logic?

OK sounds like I am correct. Now on to figuring out how to close this heat vent! Will play with the cable tensions to start....
