Help!! A/C Making funny noises

Hello all,

I am writing because my A/C has started acting up recently. The unit works fine except that at about 1000-1800 rpms, the alternator belt vibrates and makes a crazy noise. It only happens when the A/C is running. The belts are all tight and feel like they have equal tension. The belts look like they are in top shape although the alternator and compressor are spaced almost to the end of their adjustment. Any help would be appreciated.

Try adding some AC oil to your system. It might be too late, but it is worth a try.

Actually I had a whole new A/C system put in 7 months ago, that's right, 1 month after the NAPA warranty ran out! :mad

It could be your ac comp clutch is going bad but more than likely the comp about to crap.have the pressures checked for being to high.i would rather run a little lower pressures and make the comp last longer especially if comp is older.I would check pressures,vacuum system down and add correct amount of oil and freon.Quite often people keep adding freon due to a leak and they don't realize that oil had been leaking out also which will cause comp to eventually lock up.
