quick question

ok so im having another problem with my pretty troublesome 3000gt. I have recently gotten all the belts looked at after my alt had snapped and had it replaced and now it seems like i may have run into another problem with the belts from the sounds of things.

Whenever i shift or rev at high RPM's i hear a sharp squeaking/squealing sounds from what sounds to be one of the belts. However, when i turn off my ac, everything runs as smooth as can be. I can put the air on but the AC seems to be the trigger. Has any else run into this problem before or have an idea of what i can do to fix this thing without sending it in to the mitsu dealership again? Any help is appreciated!

Oh and also i was wondering if anyone has a spare power seating console switch or has one i could buy off them for a reasonable price.

Sounds like the belt is either too loose or too tight. Just take it back to whereever you got the work done, and tell them to readjust the belt. They should do it for free.

I have that same problem. Is there any way I can fix it? (It does kinda sound like a BOV, but i guess its probably not a good thing)

looks like Igo was right. I called the mitsu dealership and they said its probably the belt being loose and they said they would fix it for free.
