Hey Guys the wife's van is having a/c issues. When the A/C is run or even just the fan motor turned on, the van overheats. It also blows hot, not cold. While at the Nats she took it by a tire repair place and they said it had a relay with power running to it, but not from it. They told her it was either the Radiator Cooling Fan Motor relay or the A/C Condenser Fan Motor relay. They were not authorized to make repairs to that, so it didn't get fixed.

My wife said prior to the A/C going bad, it made a chirping sound like a bird when the A/C was turned on. Any ideas what could be wrong here? She is doubtful the relay has anything to do with the failure since it was making a chirping sound and feels it is a pulley or belt or something else. With 174K on it, my opinion is it probably has multiple issues. Thoughts on what it is or how to diagnose further?

Thanks!
