i did the whole vale thing and it was cold for a while but one of the hoses kept freezing up near the firewall wich means the expansion vale is not working properly so thats my next thing to do. so it might be the same for u, who knows get that check also. or just turn your ac on for a while and when its starts trippin look under the hood and i believe its the highest hose going inth the firewall. it should b real cold.. do your vents get all wet sometimes??
Enjoy it while it lasts

Can somebody tell me exactly how/where the cable or valve is? Got the Coupe blowing out hot as hell and it does it slightly even when not on. How do I check if there is freon in it?

the valve sits right under the air intake. the valve is hooked up right to the heater hose that goes into the firewall. i think the only way to check for freon is using a guage.

You cant miss the valve. It enters the firewall about 8 to 10 inches under the throttle body. A little advice since i am an ac man and had a wonderful learningn experience. Well the wagon had working ac a while back but it didnt work well enough. The blower made a noise and i knew it wasnt right. So i pull one from the local junkyard and i go to change it out,,,,,,,,,,,,, The blower was full of random insulation. mind you im the third owner and both previous owners are in there 60's. So im about to put the new one in. Im happy beacuse you move more for cooling than you do heating. I notice my evaporator is covered in the same crap. 85% of the surface. Needless to say the ac works too well now.

You said the needle was in the blue while charging? Im not undermining you but was the car running? It also helps to keep it at about 1000 rpm while charging.

This problem is easy to diagnose. Turn the temperature control knob to the full cool position and don't turn on the AC. If the air blowing out of the vents is heated, then your AC will be trying to cool preheated air when you turn on the AC.

There are two cables that are activated by the knob. The first cable runs between the knob and the control arms down close to the floor. Sometimes this cable slips in the clamp at the lower end. Replacement cables have a molded end and fixes this problem.

The second cable runs between the control levers near the floor and through the fire wall to a coolant valve under the hood. This cable is too short and there is no provision for adjustment. The permanent fix is fairly simple. Removed the cable. Each end of the cable is coiled to fit over a metal shaft. Use a needlenose pliers to slightly uncoil the cable at each end, effectively lengthening the cable. Now, when turned all the way to cool, the valve will be completely shut.

Finally, the heater knobs have a tendency to crack. They are easily replaced, but the permanent fix is to slide copper pipe over the plastic to keep it from splitting in the first place.
