Unseizeing window motor?

[Grand_Marquis_LSS]

Since I cant find a good window motor for my passenger side door on my Lincoln.(I understand crown vic / marquis window motors are a bit differnt) I am going to attemp to take my window motor apart and clean it up. Im pretty sure its just seized. When I hit the swithc it draws alot of power so I assume the brushes are still makeing contact. I tryed tapping it a few times with a hammer but no differnce. How reliable do you think it would be with just a good cleaning, assuming the rest of it is in good shape. I would hate to get it to roll down then not go back up.

You can try. It can be disassembled realtively easily. I was going to r&r one, water got into it, rust city inside, and the glue holding the magnets to the case failed and where stuck to the rotor and came as one big lump.

Picture of your window motor? Maybe the only difference between the lincoln and cv/gm motor is the connector.

The plastic plugs will sometimes come apart and jam in the gear. I wouldn't be too surprised if thats what happened. If the magnets come out with the shell though, its junk. Handily, all of the motors are the same, its only the gearbox head thats slightly different. If you have another motor, you can swap the gearbox onto another unit to make it go again. Only 2 screws hold it together.

And yeah, Lincoln front motors are slightly different than others. The rear motors are the same as a Vic though. I have seen brand new front window motors at Autozone. They're a smaller later design, but they fit properly and seem to work OK.

Usually, the bushings break down and the pieces jam up the gears. This is what happened to my GM. You can get bushings at autozone for about 10 bucks. If you're drawing power, as you say, then the bushings would be my first guess. When they jam, they jam good.

Ok, I'll get the Motor pulled out of the door and take it apart and go from there, Im leaning towards the bushings like you guys say, Since when I hit the switch in dims the interior lights a fair bit. I should have a crown vic motor kicking around I can salvage for parts also

[marquisman]

take er apart and go from there, thats my advice. if you need a motor, swap the gear set with the merc/vic motor

[Grand_Marquis_LSS]

Yea It really sucks not being able to roll it down now that the hot weather is finaly here

I've also had the plastic main gear shatter and jam one. new gear... problem fixed.

[GM_Guy]

If you havn't taken one apart before, take off the flat plate where the gear pokes out of. Under that plate is the plastic gear and bushings everyone is mentioning.

Window is working now. Didnt have to replace the motor, The window reg was just kinda sized up, lots of penitrating fluid, and grease fixed it. Rolls down good now but still have a tight spot when rolling it up. (About when the window gets half way up) So it should start working better with more use.
Oh and that is a pretty complicated looking window reg. my god

If the magnets come out with the shell though, its junk.

I must be completely misunderstanding this comment. On the window motors I've pulled apart (on that end, anyway), the magnets all appear to be stuck firmly to the shell of the motor with a rather serious adhesive!

Too help out the window even more try out some dry silicone spray in the window channel weatherstripping.

They're supposed to stay on the shell. What I meant is that if they come out of the shell, meaning with the rotor instead of remaining glued to the shell, its shot.

Gotcha. That'll tend to put a lot of drag on the guts of the thing. Does seem logical that once such a situation is discovered, the guts would typically be damaged to the point where regluing the magnets is pointless.

[gadget73]

they usually aren't damaged but without a stationary magnetic field, it just doesn't work.
