I installed a new AC belt after going without one for a few years and now I have a whine.

Also, when I press the switch for AC nothing happens. When I force the AC to come on in HPtuners, the engine dogs a bit so I know it turned the pump on.

Any ideas as to what would cause the whine, and why the dash switch won't turn on the pump?

the pump seized up? Was there a leak before?

If it wasnt used/run for a long time it could be on the out. Does the a/c light on the dash flash or go solid?

I don't think there was a leak and it's not seized. The A/C light stays solid.

Could the idler pulley be bad?
