I just got this vehicle. The rear glass that slides down will not go down when I hit the switch. I've checked and there's voltage getting to the motor and regulator and I even replace those but it still will not do anything. I have read on order models there is some sort of training procedure but I have not seen one for this generation to Sport Trac. Is there one?

Hello,

There does not say there is a reprogramming to the new motor. here are the instructions and diagrams to do the repair. Do you get power at the motor and ground? Here is a guide to help:

Thanks Ken,

It is actually the motor and regulator to the rear glass of the truck not in the door. I should have been more clear. Do you have any information on that? Thanks!

Hi Ken,

I tried the initialization procedure with no luck. Thanks for the information. Do you have the pinouts of the plug going to the motor?

Thanks,
Bryan

There is an Acc/Delay relay that I would look at in the smart junction box on the left side of he dash. here is a guide to help check it with the wiring diagrams for the rear window:

Ken, I'm stumped! I trace the wires on the plug and checked all the voltages everything going to the motor is correct I get 12 volts where I should get 12 volts in the switch goes 12 volts when I go up in 12 volts when I go down but the motor does nothing. I even tried plugging in the old motor and doing the initialization procedure and neither motor does anything. I am thinking about trying to get a warranty replacement and try another motor and regulator what do you think? Thank you for all your help.

I would check the system grounds next, connect the test light to power and run the test. Let me know.
