For a temporary fix, you can pull out the window switch and swap it with one from the passenger side.

Then you can sit at a table to carefully take apart the faulty window switch and clean the contacts. Rub them with newspaper to get the oxidation and build up off, and reassemble putting the contacts in the exact same position.

If this doesn't fix it, you need to buy a new window switch.

when i press the window switch when the window is down the motor starts up and you can see the window struggling to go up. when the window is up i press it to go down and it starts to work then just falls all the way down sometimes if i dont get the window in the right position i will close my door and the window will just fall back down

Then it sounds like there's a problem with your window regulator.

The door panel will have to come off and you may need to replace the regulator altogether. Try finding a good used one, although most are pretty worn out by now.

I had the same problem when I bought my 87. The motor and switch were working fine, the window just kept falling into the door.
And I had to hold it up to get it to close. Most annoying.

When you open up the door panel, you'll see a combination of levers and plastic rollers that work like a scissors lift to raise and lower the window.
Sometimes, the plastic rollers get brittle and break, and this causes the window lifter mechanism to malfunction causing the symptoms you describe
(window falling in). When you get the door panel off, just take your time and work through it. It's not easy getting it all back together.

If the rollers are good, once you get it back together, just make sure you lubricate all the joints and rollers really well. Mine works like a new one now.

BUT....if you have some broken rollers, I think there's a fix for it, but you'd have to do a search.

Hope this helps.

There's a procedure on the Clark's garage website in the Garage Manual section on door panel removal. (It's easy to do.) Once you have it off you'll see what's broken. It could be the plastic rollers, or the window could have come unglued from the metal track it sits in.

i got the rollers from partsheaven some time back.

the window sits in a channel and the rollers keep it in place as it goes up/down.

i found it easiest to get the window in the tracks at about mid position and had to feel for it cuz i could see it.

Bump, how did you seal the window into the rubber/track? Mine has fallen half way out.

Oh....the bottom piece that it sits in....I think.

If so, I cleaned the windows as well as I could, cleaned out the rubber piece on both sides as well as I could, and then I use 3M Trim Adhesive on both sides of the rubber, set the window in, rolled it up all the way, and let it sit overnight.

I'm sure there's a more appropriate adhesive, but that worked just fine for over a year (until I got hit in that door).
