ac question
my 94 mustang gt blows hot air when the AC is on. the condenser doesnt make noise so im assuming it works but just needs to be recharged. im just curious if someone could tell me what recharge kit to buy. it should take the 134a correct?

If it has to be recharged it already leaks. Go to autozone or any of the other parts stores look for the do it yourself cans of refridgerant with the guage. There should be a temp/pressure chart printed on the can or in the instructions. Pay attention to the chart because you can overcharge and damage the system. There is a pressure switch on system that protects compressor from damage when there is a low refrigerant issue. Depending how low it is you may have to add some before compressor turns on. Make sure car is running and a/c is turned on while adding and keep an eye on the gauge. When compressor kicks on add a little at a time until you reach the pressure stated for the temperature. good luck

What you need to do is turn the a/c on and see if the compressor clutch is spinning or not. If not then you need to check for voltage at the connector. There are many different things that can be wrong with an a/c system and it can be confusing if you don't know what your talking about.

This usually is a low pressure switch kicking the compressor off. That means that it does need a recharge and checked for leaks.
