Driver's side window will not roll down.....

A few days ago my driver's side window stopped rolling down. It happened all of the sudden with no warning/noise before or after. Now, when you press the switch, there is no sound/no motor noice/nothing. Passenger side window still functions as normal from either the passenger door or the switch on the driver door.

This is a 1993 E250.

Any thoughts on how to go about fixing this? I'd like to do it myself but lack electrical tools that would help chase down the culprit(volt meter type stuff).

Thanks!

If you don't have tools, try safelite or other glass shops. Be sure to mention it might be the regulator or electric.

I just did some fiddling.....here's where I'm at:

I pulled the switch panel and swapped the switches from driver/passenger. The passenger side rolls down regardless of which switch I plug into that side. The driver's side will not roll down with either switch.

The fuse panel shows one fuse for both windows, so that rules that out.

Seems to me, at this point, that it must be the motor. Right?

Perhaps the wiring harness inside the drivers door or a limit switch on the motor.

You can remove the door panel and disconnect the harness to the window lift motor.

Then apply 12vDC to the motor , this way you are only testing the motor .

Reverse the polarity and you reverse the rotation of the motor. ( up - down )

I think on this particular vehicle you must remove the regulator and lift motor as a unit .

detailed instructions here -

Something similar happens on my 89. Took the door panel off and removed the motor and regulator/lift assembly. The motor ran but the plastic three lobed gear was toast. I got a rebuild kit for the plastic parts from Rock Auto.

I ordered up the new motor/regulator and went to install it over the weekend.

Rivets. The motor/regulator is mounted with RIVETS. Thanks Ford.

So, tomorrow afternoon I'll get going with a drill and get this job done. I did some testing with a volt meter and the motor is definitely getting power, so it has to be the problem.

You'll need a big rivet gun as well if you don't have one

When I did mine I used bolts instead of rivets. Got this idea from the service manual. Not the easiest things to install in the door panel but they worked.
