I need to replace my blower motor resistor but can't seem to find one anywhere, the original part number is E5ZH-18591-AA. It has 2 different connectors going into it, one goes into the main harness with 4 wires, and the other goes into the blower motor with 2 wires. The only option any parts store has is one that has only the 4-wire connector. The local dealer was no help. Anyone have a similar issue?
