The AC is charged and the blower is working but no cold or cool air is coming out. When I turn the control to hot I get hot air. On cold it is about outside temp.

you say it will blow cold and hot air for only a few minutes. You don't say but I assume you mean will blow cold a few min. when turned on AC max , blow hot only a few min. when turned to heater hot. Assuming thats the situation and you say AC charged and shows good on the low side -you should charge the AC to a full charge on the low side will cause problems with the AC air compressor kicking on and off. I suggest while the engine is running and turned to AC cold max watch the AC air compressor clutch to see if it does indeed kick on and off if so charge completely. As far as the heater make certain you coolant is all the way to the top and the best way to do this is when engine is completely cold remove radiator cap and fill completely and completely close cap then fill overflow container just to the cold level. That should fix your problem.
ok, missed the part about the rear ac working, the part that causes this is called the air temperature control blend door actuator motor, it is an electric motor driven gear drive that moves the plastic door inside the air ducking to mix or shut off the hot or cold air from the ac evaporator core or the heater core, you will need to replace it.
Is the air actually blowing into the car?But it's just hot?It sounds like your blower motor is not turning to blow air.you have a fuse,check the switch that controls the blower,and the blower motor it self.
i assume u r refering to the cooling fans,,, if this is so the freon is low ,fans come on and lower the high side ,there fore lowering the low side and the low side switch cuts it off and on,,charge it up
Is the heater working? Turn the A.C. off with the car at an idle. Turn the A.C. on and listen for the compressor to turn on. (should hear a click under the hood and the motor should change pitch. If no noise, the compressor is not comming on. The o-rings were bad about leaking on these cars, letting out all the freeon. If there is no freeon, the low pressure switch won't let the compressor run.
you going to have to tear the dash apart (ac control panel) to see why your switch is not working. The control valve unit works on vacum systems and you need to find out where is leaking or the hoses is old and broke off. If your ac compessor still working and blowing cold air but does not adjust the temperature, it will be in the control valve. Is very easy to fix if you locate the leaks or a bad valves. hope that help some.
When I turned the ac on the temp came back down.
