I had previously posted the following in alt.trucks.ford and wanted to share my success story... thanks to Joe and Steve.

All,
Need a little help here. Seems my power window on the
driver's side no longer works. The door switch and motor
run fine but the window doesn't move. When I bought this
truck earlier this year I was worried about having such a
fancy option on such a simple truck. :-)
Anyway, I'm going through the Haynes repair manual (what a
POS) and have the door panel already removed. I can feel
the motor turning but there's no movement on the massive
gear that's supposed to move the window. I take it some
other intermediary gear is missing or broken?
BTW, when removing the door panel I found a small piece
of black plastic that looked like it could be part of the
problem. True?
There doesn't seem to be a lot of room to work in this
area. Am I looking at a repair that's going to be a
PITA or something simple with a little guidance from
the experts here?
Thanks for any help. I'll post a follow-up if/when I'm
able to fix this (hopefully simple) problem.

Your explanation brings back memories. I've encountered that exact problem on
both doors.
The electric motor turns a armature shaft of course, which turns a gear within
the attached box. That gear has three nylon (appears to be nylon) barrel shaped
components which causes the unit to engage the window apparatus. They are
designed to give somewhat shoud you hold the up or down button in for any
length of time when the window hits it limit (who does that?)
The nylon (??) barrels shatter eventually and the electric motor spins away and
does nothing. You can either go to a Ford dealer and pay a great amount of
money for a new motor assy, or buy a used one and encounter the same problem at
some point later on, or do what I did as follows.
Purchase a aluminum rod that is 3/8" in diameter. Carefully cut three lengths
of that aluminum rod to be the length of the previous nylon barrels and
assemble the motor/gear assy.
My windows are working great since I repaired them in this fashion three years
ago.

And then "Steve" followed up with:

There's a worm drive gear inside the motor. I suspect the larger plastic
gear is stripped. If you pull up on the window, I'll bet it'll go a ways
and then stop again. Replace the motor. $50 at NAPA.

Upon inspecting the inside of my door window motor I could see that the
worm gear appeared to be fine and not stripped.
However, it was obvoius to me that the nylon rollers were destroyed.
So I went down to my local Home Depot and for $3 I picked up a 3/8" x 36"
solid aluminum rod.
I cut 3 "rollers" about 10mm in height.
I then packed the entire motor assembly with new (synthetic) grease.
The picture below shows the broken nylon rollers.
It also shows where the new roller are to be placed via the hot pink
circles.
 Considering the age of my Ranger (it's an '89)... I suspect the passenger side motor will eventually give me some grief. When it does... I now have the necessary knowledge to perform this repair without any problems. I have no idea if all vehicle power windows are designed this way. If so, then hopefully this page can serve to help someone in the future. Thanks! |
