faint grinding noise

their is a faint but noticable grinding/rubbing noise coming from ac compressor pump area not sure if it is that but its in that area any ideas?

Are you running either your a/c or defroster?

no ac or defroster at the time of noise

I have the same problem,mine has been doing it a year now and has only gotten worse, dose that front disc peice, clutch I am assumeing, stick while it makes that noise?  Mine also only really does it when it is off.

you need to verify the noise is indeed coming from teh ac compressor. Put a screwdriver on it, and put your ear to the handle. If its making noise you will hear it, if that ain't the source you will know that too.

If it is your ac compressor, short of replacing it there really isn't much else you can do. this repair will cost $500-$1000. Almost as much as a tranny, unless you can do the work yourself. the most important thing is evacuating the freon, then recharging the new unit.

My Blazer does the same thing. I was also thinking it was coming from the A/C Compressor area.   Could this just be the A/C clutch and pulley assembly ?

Anyone else got any info on this problem ?

As Hanr3 has suggested, put a screwdriver on the compressor and your ear on the handle of the screwdriver ( it works like a stethescope), listen for the noise and see if it's there when the compressor clutch is engaged , disengaged or all the time.
If it's there all the time, remove the belt and turn the pulleys by hand and see if you can feel the problem.
It's possible that it's the bearing in the compressor.

i got the same noise with my 03 s10 blazer asked a buddy of mine and he said the same thing but his occured the same way mine did after washing off the motor at the carwash he said his was the tensioner pully but i havent checked anything yet but his stoped when he replaced that if this helps anything what everyone says about the screw driver trick is tall true
