LAST FRIDAY I WAS DRIVING MY LEXUS ON THE FREEWAY AND THE A/C WAS WORKING FINE BLOWING COLD AIR. 45-MIN TO HOUR LATER I WAS DRIVING HOME AND IT WAS WORKING FINE THEN ALL OF THE SUDDEN I HEARD A HIGH PITCHED SQEEK OR WHISTLING NOISE AND THEN THE A/C STARTED BLOWING WARM. I TURNED IT OFF AND THEN TURNED IT ON AGAIN AND THEN THE A/C LIGHT STARTED BLINKING. I ALSO NOTICED THAT WHEN I TURNED IT ON AGAIN I CAN FEEL A LITTLE JERK IN THE CAR AND IT SLOWS DOWN IN ACCELERATION A LITTLE BUT NOT MUCH. WHEN I GOT HOME I PUT THE CAR IN PARK AND THEN TURNED ON THE A/C AGAIN AND IT STARTED MAKING A LOUD SQEEKING NOISE REPEATEDLY AND MAKES THE CAR KIND OF SHAKE A LITTLE. WHEN THE CAR IS IN PARK AND I TURN ON THE A/C IT SQEEKS THEN TURNS OFF AND THEN SQUEEKS AGAIN AND REPEATS THE SAME PROCESS AS THE A/C IS KEPT ON. EVERYTIME THE SQEEKING NOISE IS MADE THE CAR KINDA SHAKES A BIT. THE NOISE I AM HEARING SOUNDS LIKE A BAD BELT. DOES ANYONE KNOW OR HAVE ANY INPUT TO WHAT THIS MIGHT BE OR WHAT NEEDS TO BE REPLACED? PLEASE LET ME KNOW!
 
sounds like your belt is still on because you are hearing a squeek when you turn on the ac. Therefore, I'd have to go with the a/c clutch. Most likely it has gone out on you. The clutch attaches to the compressor. The belt attaches to the clutch.
 
Sounds like either the belt is going bad or your compressor has failed. Do not drive with the air conditioner engaged until you get it looked at. If the problem is just the belt, your repair service should be able to diagnose and repair easily. If it is the compressor, this can also be repaired easily, and if done correctly, it will last at least another 9 years; however, it will be a bit expensive. You may be tempted to put this repair off because winter is coming, but don't. If the seals on the compressor are damaged, you will leak out all of the refrigerant and probably do additional damage by leaking airborne contaminants into the system. In any event, have a competent automotive air-conditioning specialist diagnose and repair the problem. I would prefer the dealer in this case.
 
Would have to be under your hood to verify, but it sounds like your AC compressor is locked up.
