It is a KAE Blower Control unit purchased from ******** AZ. Instructions say that "the surface of the blower control unit is pretreated with a very efficient proper amount of copper=heat=agent"

It seems like blower regulator is grounded, motor will spin when everything connected and I ground the blue wire. If I unbolt the blower regulator from the blower and ground the blue wire, nothing happens.

Any ideas????
