Needs to be done by person certified to handle refridgerant properly evacuate system replace compressor vaccuum system and leak check properly add correct type and amound of compressor oil properly add refridgerant
follow the refridgerant lines from the compressor.
A. you are probably out of Refridgerant in your AC B. you probably have a leak in your AC compressor and lost all of your refridgerant
You need to recover the refridgerant and unbolt the hoses and remove the belt and unbolt the compressor. If you don't want to reinstall, you will need a shorter accessory belt.
A lot of cars won't let the compressor kick on unless it has enough refridgerant. Try recharging the compressor all the way and if it still don't work, you might need a new compressor.
Evacuate the refrigerate, remove the belt, disconnect the AC lines with fuel line separators, unbolt the compressor.
How do you add refridgerant to a 1997 Geo Tracker?
To compress the refrigerant. The refridgerant (freon or whatever) is a liquid and when it expands to a gas it absorbs allot of heat (makes stuff cold). then the gas which is now not cold but warm is sent back to the compressor where it compresses it down to a liquid again so it can start all over.
It sounds like you are low on refridgerant, i would have your A/C lines inspected, and maybe try to recharge it, could also be a bad A/C pump.
I am retrfitting ac on 93grand am and the refridgerant cans to recharge it say "includes oil". I have to have the ac system evacuated and was told this would pull most of the oil from compressor out. One guy said the oil weren't compatible so I should remove compressor and dump the oil out the back of it. Hope this helped
Always use safety glasses and gloves! To remove the A/C compressor you must evacuate system & properly dispose of old R-134A. Then unbolt and remove old compressor. (You should be certified to handle R-134A to charge system)
If it is working fine, and the noise is only when it is disengaged you should only need to change the clutch on the compressor not the entire compressor. If there is room to pull the clutch off on the truck, then there is no need to evacuate the refrigerant.
