Hi,
It could be the clutch in the AC compressor is failing. If it completely locks up it will break your belt and likely cause the car not to run @ all. Get it checked out ASAP.

Td

the air cond requires the belt on or the pump cannot rotate as the air cond is belt driven on every auto that i know of. now if the belt is slipping it is a cause of one of two things. belt is stretched or not tensioned properly, or the air cond clutch is froze up. when you turn on with no belt the clutch is engaged and you will not be able to turn pump with ease. Install new belt and have air checked for proper freon fill

the blower motor has no affect on the AC system,
start the engine and turn on AC and watch the AC compressor to see if clutch engages,if it doesn't the system isn't full,if you are correct the clutch should be engaged and should quit when you change heater speeds,

Problem with Aircon clutch OR your reves are to low ,,,with aircon working revs should be about 650 rpm min

If aircon clutch then it is trying to seize up....

what won't work? the interior fan or is all else well except the cooling part? if the compressor does not come on, then perhaps you need to refill gas. in the very front of the car under the hood, you remove the plastic covers where the hood opener is, and you will see some pipes & a canister. on top of this canister there is a clear small round site glass, you can check there for gas if you have dye, or you can unscrew the cap over the refill nipples and depress with you finger nail, air (gas) should blow out under good pressure, not a little only. there is also a fuse you can check situated in the same place, this is for the compressor

relpace the clutch pressure plate and throwoout bearing. It all comes in a clutch kit.
