My HVAC **** is broken, I took it to the dealership and they said I needed a A/C-Heat control head. They said it was binding and it caused the HVAC **** to break when my wife try to adjust the temp. The dealer wanted to charge me $692 for parts and labor, I don't want to pay that muchbecause we are planning on trading the car next year. So where can I order a A/C-Heat Control Head besides the dealership?
