$.09 fix for Grand Marquis power window

Stan Kasperski · 2005-01-18T22:56:06+00:00

I fixed my wife's '92 Grand Marquis' rear passenger power window motor this weekend for less than a dime in parts. Instead of getting the ~$30 kit that replaces the gears for the window motor, I decided to try using 3 ea 1/4x20 nuts from the local Home Depot at $.03 each. I'm tired of spending 30 bucks plus when the only thing that breaks are the three little round pieces of plastic that connect the inner and outer gears. They act as a shear pin on a prop, but you can't get just the three plastic cylinders...only the kit which consists of the outer nylon gear and the inner steel gear along with the three cylinders and some grease. I never had to replace the gears anyway...only the plastic cylinders.We'll see what happens, but the price is right!Stan K.

Not exactly. The door is coming down WITH gravity - the window is going up against gravity. The door is running on an open exposed track, the window is running in an enclosed weatherstrip, which gets stiff and freezes. The window NEEDS to be able to be cranked up against a resistance for security reasons.

Also, a garage door has an emergency closing mechanism - you can unhitch the door from the closer to close the door if and when the closer fails. The window has no such mechanism.

Now, if you want to install a "light curtain" like is used in industrial applications, and has been used in a simplified form on garage doors, all you need to worry about is keeping the transmitters and recievers clean.

Much more viable solution, but still not nearly as simple and effective as a simple "lift to raise" switch.

The switch on the old "AeroScare" was very often accidentally activated by bumping it with your leg when shifting position in the seat. The switches on the '96 Mystique a a huge improvement, but not foolproof. Would be SO simple to make them safe.

Both controlled by a motor forcing the action. The same thing.

Not quite.A garage door can be set up so it will basically fall closed, so virtually no current is required to close it. It can then be set up to stop if there is any resistance to closing, without much danger of the door being stuck open. A 5% increase in closing current means something.

By contrast, MOST power windows require significant current to raise them even at the best of times. A bit of grunge in the track, or whatever, causes an increase in closing current so it is hard to get them set to the point where they will always close effectively, yet will stop before doing harm if a body gets in the way. A 5% increase in current means nothing at all.

Pot kettle black. bla bla bla.....

Try living in the real world and experience what the rest of us see.

Have fun with your untested theories.

Yet they still have adjustments for restrictions in either direction. Wonder why that is?

That is EXACTLY my point... how many power windows in 3 - 10 year old cars have you tried to fix to cure stalling problems?

I've done a few... all different causes.

I have ALSO had to adjust more than three garage door openers to trip reversing switch .... The garage door is infinitely easier to handle, only because you can adjust the door spring tension first, then the door with the opener.

Tolerances on a garage door are on the neighborhood of 1/4 inch, even more before they are all the way closed.

On a car window, about 1/8 to 1/16 of an inch.

So my "untested theory" is empirical and practical FACT.

YOURS is actually tested but will NOT work in the "real world"
