Ford Expedition blower motor overheating causing recurring resistor and wiring harness failure despite recall 22S56 on Ford Expedition

Some Ford Expedition owners report experiencing ongoing issues with the blower motor overheating, which leads to recurring failures of the resistor and wiring harness, despite the recall 22S56 aimed at addressing blower motor problems. These owners note that the recall may not cover all components related to the blower motor, leaving the resistor and harness vulnerable to failure. Even after the recall repair, some have reported failures in the blower motor resistor connection at the wiring harness plug, indicating persistent issues within the blower motor system. Additionally, the resistor, which is essential for regulating motor speed, can overheat if the motor draws excessive current, contributing to further failures. Over time, natural heat can cause the resistor to fail, and factors such as a worn-out blower motor may exacerbate these recurring problems.
