I have a '78 F-100 and the heater is acting funny. Whenever it is turned on it makes a high pitched screaming noise. I've looked at many places for a replacement heater fan but the fans they have dont match mine. I have just a heater with no a/c, and the fans ive found with that description mount to the firewall from the engine compartment while mine mounts from the inside of the cab to the firewall. any suggestions?
