Auto Air Conditioning & Heater Repair: Air Conditioning Noise on Toyota Previa, high pitch, auto parts store

Question
I have a 91 Toyota Previa that was recently recharged with coolant (Been retrofited to accept new coolant a few years back). When I turn on the A/C I get a high pitch noise. What would one look for? Bad belts?? Bad A/C clutch??  Your help is appreciated.

Answer
Since I can't HEAR the noise it could be the BELT or the A/C clutch.

Go to any auto parts store and purchase an aerosol can of BELT DRESSING.

As soon as you hear this noise, leave the engine running and with the noise evident spray the belt(s) with the belt dressing and see if your problem is resolved,.
