93 A/C problem
When the A/C run it blows out warm to hot air when its turned on cold. It's probably the cold gas thing that's empty(name is slipping my mind). I need to know where the location of the connector goes to recharge it so the A/C is cold. A picture will help alot.

Try this B.T.
Your system may be low on refrigerant (because it leaks somewhere) or it could be something else. When you turn the AC on you should feel the compressor clutch engage and drag down the motor. If your incoming air is not cool but the compressor continues to stay engaged it is probably just low on refrigerant and
not completely empty. You see the refrigerant also contains the lubricant that is
necessary for the internal parts of the sealed system (mainly the compressor). Therefore there are low and high pressure switches that will kill the operating voltage to the electromagnetic clutch that turns the compressor. Now assuming
that the high and low pressure switches are working correctly and are not bypassed, if the compressor continues to stay engaged but incoming air is warm
then you may be able to get by with giving the system a little charge of refrigerant. Next problem is your probably going to need R12, should say on sticker on inside of hood. If you are going to use R12 you may have a hard time getting your hands on some depending on who you are and who you know. I'd try a appliance repairman because lots of older refrigerators use R12. Some car
places that do AC might hook you up but they are probably going to have R134.
Your car may even take R134 I cant remember. I'm thinking my OEM hood sticker
says R12 but I could be mistaken, besides I have no AC or power steeering. You
should try it. Without the AC and power steering belt on you might like the way
the car drives. You get really nice feedback of what the car is doing through the
steering wheel and with my car the first thing I noticed was the turbos spooled up quicker. Anyway, you charge the system using the needle valve on the low side compressor line. That is the larger diameter tube of the two coming off the compressor. Follow the big line and you will find the needle valve.
PS: You can convert to R134 if needed but you will have to evacuate the system
and possibly change some o-rings. Then you will need to vacum the system,
check it for leaks and then charge it.
