Need help; Strange Noise and A/C died; I'm confused
This one has thoroughly confused me, and I don't know what to diagnose here.
I was on my way back home from Miami to Orlando yesterday (about 3.5 hour trip), and at about the 1.5 hour mark, I notice the A/C is no longer cooling properly. I turned the A/C off and on a few times, jiggled the temperature a few times, but to no avail; the A/C officially crapped out...........since it was still kinda hot, I left the A/C running as was for another hour or so, since it was still blowing mild air, and my power windows don't work. I heard NO strange noises at all......everything seemed fine.
When I get off the Turnpike to pay my toll, I hear a horrific constant wheezing noise from the engine; it's loud, and crazy, and I don't know what it is. Fearing the worst, I turn off the A/C, but the noise continues. I stop at the first gas station, turn off the car and pop the hood to see if I see anything strange; I see nothing. All my gauges indicate proper levels of everything, and the car was running fine. I turn the car back on, and the noise continues, but I have no choice but to continue home, which is still an hour away.
For the full hour, there are essentially NO traffic lights; the car ran perfectly fine, and I decided to turn the VENT on rather than the A/C. AFter about a good 30-35 min., I finally hit my first red light, and I notice the sound is gone. No strange noises for the remaining 30 or so miles, so I'm thinking it's obviously something A/C related (i.e. compressor, pulley, a/c clutch, etc.).
However, this morning, I turn it on, and that God awful noise is back........It sounds like it's coming from the A/C compressor area, but I'm confused.........if the A/C is off, why would it continue to make noises like that...........and furthermore, why would it have eventually stopped last night after driving for 30 minutes........
I'M SO CONFUSED..................HELP!!!!
