Noise when aircon is on
I wanted to see if anyone has any ideas on this - the dealer is not taking the correct approach and it's irritating me.
My 2005 3.2 GT has recently (about 6 months) developed an annoying whine when the aircon is on and the revs are at about 2k-2.5k rpm. I initially suspected an aircon pump (since as soon as I switch it off, the noise disappears) and complained about it to the dealership. They changed the aircon pump, and the noise was still there. I complained, the replaced the pump AGAIN, and, yep, the noise is still there!!! Morons.
Anybody ever had this problem? The noise sounds almost like a dry belt, but more subtle...this is why I initially suspected a worn bearing on the pump.
