I bought a 89 Grand Marquis and the power windows need some help. Both
passenger side ones go up and down but not all the time. The drivers window
doesn't move but you can hear the motor run. The drivers side rear worked
the other day but now you can hear the motor but no movement. What do I need
to check or replace? I know after market motors are available, do they have
everything I need or do I need a lifter as well? I'd like to fix these and
the front power door locks and have everything working again.
I think those window motors have a rebuild kit available - AutoZone should
have them. There are nylon parts inside the drive gear that act as a clutch
and eventually fail. The kit contains a new gear and inner parts. You
should also lubricate everything that moves with the window and check for
binding or the new parts will fail too. Power door lock failure is usually
due to moisture entering the lock actuator. New exact replacement units are
likely still available from Ford/Mercury. There are inexpensive aftermarket
actuators available that are used to add power locks to cars, they can be
used too but require some creative installation to make work. They are a
lot less expensive but are very generic.
Hope this is helpful. PoD
Another power window question... 99 Ford Windstar. Right Front Passenger
window inop. Getting electric to the motor but motor must be out.
Wiring diagram indicates a circuit breaker on motor. Is this true and is
it accesible? Would be nice to reset circuit breaker and lube the thing
instead of buying a whole new unit. Anyone know?
If there is a breaker, it's a self-resetting type. Do you notice any
indication of the motor trying to operate like lights dimming? I repaired a
motor once that had a broken connection near the brushes but most often they
fail either due to water inside or overwork from a tight window mechanism...
You might pull the motor and reconnect it to the harness, then work the
switch and see...
You want an simple and cheap solution..........
Try slamming the door a couple of times while pushing the up/down button
Sometimes that works
If you already have the door panel of, try tapping on it while pushing
One of the dumbest inventions on cars has to be power windows. We
have them on a 1988 Celebrity. This car's for sale. A few weeks back a
lady came to take a look. She rolled one window partially down.
Unfortunately, we didn't catch it in time. There wasn't enough juice
left in the battery to roll the window back up. A garbage bag's
covering it now. At least she didn't roll it down all the way.
Thanks for the help guys. It is surprisingly easy to take the door panel
off the Ford as compared to my Jeep and others. I can get at the power
window mechanism but it involves drilling out rivets to remove it. I'll
try the door slam but don't expect it to work as its been inop for a long
time. Took some kids fishing in my truck and they couldn't figure out how
to lower the "old fashioned" crank window!!
Before you drill out the rivets in the regulator look closely at the iner door
for dimples in the metal where the window motor is located. The dimples will be
located over the motor mounting bolts. Drill a ~3\8 hole at each dimple then
the mounting bolts.
Smacking the motor may make it work for a while but it will stick again,
fully down during a rain storm. :)
New window regulator and electric motor installed. Problem solved!!
Removing the old rivets was a real pain.. lots of Dremel tool grinding in
restricted places. Reinstalled the unit with bolts, lock washers and
locktite thread sealer.

Oh, yeah...I want that car.
Trying to sell a car with a run down battery... and put a garbage bag on
it rather than charge or jump it!\
You are an idiot! But then, "WEB tv" says it all...
