SO my 98 explorer has been having issues with the blend door actuator. I saw that the actuator motor was not moving so I bought a new actuator motor assembly and installed it. No change. The blend door motor is not moving at all. This tells me it has to be something wrong with the actual A/C control unit or a fuse or relay of some sort in the wiring going to the blend door motor. Any suggestions on what I should check next?
