a/c problems

We have a 98 chevy lumina. Last week we notice when drivng with the a/c on that every so often what looks like smoke would come thru the vent. Its been really humid here. Then today I noticed I high pitched noise. I Pulled over and turn car off. The noise was still there. Then when turning into neighborhood it stopped with 3 loud chimes like when you start the car. Is this the compressor going bad. Any help would be nice as We have a 4 day trip planned later in the week. thank gary

Welcome to AF, regarding the mist in the ac vents, look for a clogged drain tube, r/s of cowl down low behind the engine. Noise ,has to be determied on site for obvious reasons.

well the blower motor went out today. Hope that this is the only thing wrong. thanks for your replay. gary

WELL JUST COME IN FROM LOOKING AT THE CAR. IT SEEMS THAT THE PASSENGER SIDE FOR IS SOAKED. lOOKS LIKE A HEATER CORE PROBLEM. BUT WHY WOULD MY BLOWER FAN QUIT? LOOKS LIKE THERE IS MORE PROBLEMS THAN i THOUGHT. THE A/C HAS BEEN WORKING FINE UBTIL THE BLOWER MOTOR STOPPED TODAY. I DID NOTICE THAT THE AIR COMING FROM THE VENT IS VERY HOT. DOES THIS MAKE SENSE TO ANYBODY. i HOPE THAT THERE IS NOT ANYTHING WRONG WITH THE COMPRESSOR. ANY ADVICE OUT THERE TONIGHT. THANKS GARY

Check if you have lost coolant, is the wetness water or antifreeze, again the drain can cause this, if water.

Yes the drain was plugged. It draons fine now. But I still have the problem with the blower motor. Thinking that the water might have something to do with this. could it have blown a fuse if it got wet and went to ground. If so where would the fuse be at for the fan motor. thanks for the quick replies. This forum I see can be really helpfull. thanks gary

Blower fuse should be in the r/s dash fuse panel I believe, see if there is 12v to the connector also.
