I'm not certain, I understand the "TEST" procedure that you describe...The wire harness plug from the motor to the resistor pack/module on my car, is made up of (1) green colored wire, and (1) black colored wire....I'm assuming the "black" wire is "ground"...and the "green" is "HOT"
*** I should un-plug the motor harness from the resistor pack/module..
*** Then take a jumper wire and re-connect from the "HOT" output "pin" of the resistor pack/module, to the green motor harness wire...
*** and take another jumper and connect it from the "GROUND" output "pin" of the resistor pack/module, to a metal spot on the dash..
Is this correct ???
I'm "afraid" to ask you...what is the "CONTROL HEAD", where is it ?? and if it's the control head, am I opening up another can of worms ????
******another follow-up question...this is about the screws...
I believe I can see the one (1) (( FROM THE TOP)) screw....but I can only see three(3)
of the (( FROM THE BOTTOM)) screws that you describe.....
If the (4th) is where I think it is..(behind the housing)...how in world can I get to it ???
