Kinda sounds like your AC clutch isnt properly working to me.

 

i think i'm having the same problem.. wat exactly is a ac clutch, never heard of the term..

 

the end piece of the shaft on the A/C compressor....it might be slipping....or it could even be your A/C belt..as when yuo turn on the A/C...the clutch engages, and puts more load on the pulley.

 

my car is acting up though... when i turn on the ac (half way up or more)... the passenger vent would make squeeling noises... This usually under breaking too. U guys got any suggestions?

 

there's mice living in your ventilation ports .. good luck to this, would love to hear the answer too
