You can put it back together, but in my experience, replacing the window regulator is better than trying to use the old parts, which may be damaged to the point of allowing the glass to fall.

Even a used window regulator from a salvage yard would work better than one that has failed before.

I had a body shop do it, you can probably do it yourself with practice. But, if you want it done reliably, have the body shop do it.

Probably an hour or two of labor.

    Also, when you take the panel off the door, check that the glass is secured through holes to the channel that is horizontal that receives the window.

    Some windows have holes there that have a rivet or other fastener that keeps the window on.

My driver side automatic window made a crunching sound and then my window lost all power and did not move i bumped it and it fell down uneven i have a feeling it has come off the rollers would i be able...

Sound like it has detached its self from the window regulator and possibly come out of the guides. Depending on your level of expertise I would suggest you see a good mechanic. If you are rich, you can take it to a Subaru dealer.

Got in my car, went to roll down the window and heard a pop. Then the window rolled all the way down and now it won't roll up.

Sounds like the window track fell off the window regulator. Sometimes you can replace the roller that goes between regulator & motor, but most times you will need to replace window regulator. Take off interior door panel & see which option is possible.

I have a problem with my window i put it down one day and it fell down inside my door panel the side that is suppose to be under the rubber.

Remove the inside door trim and see what has gone wrong.
you may have jumped the rollers (if it has rollers) out of the track and it has dropped to the bottom
Not sure if you have electric windows or not but.

Rear passenger side window just fell down and won't go back up. is this possible?

Yes its possible, the roller has come out of the track You would have to remove the arm rest and panel screws off and remove the cover with the door open unsnap the clips on the door and let the door hang down use a flashlight to see the roller that's off track pick the glass up and slid into the glass guides and move the window up till you get the roller into the track, have the key on in case you need to raise the window up or down to get it to go into the track, if the roller is broke you can buy one at a junk yard, if the roller is ok then the stop pin may have fallen out and you will have to use a roll pin to keep the roller from coming out of the track. Hope this helps.

Rolling down power window and it fell off track

Ok I can't see the car so I don't know how to tell you to fix it. It would be nice If I knew what you were working on, but if you go to the dealer and go to the parts desk and give them more information than you have me they could print you a picture of the door and glass and frame assembly and most likely won't charge you for it, Since you will have to buy rollers or other parts to fix it.

Left front window fell inside door, vw golf 2000 modal electric windows

Either the glass came off the rail, or the roller came off the rail. You'll have to take your door panel off and see what happened. It's usually an easy fix.

1994 Toyota 4Runner, Rear window goes down on one side but not the other and then won't go back up. The key and the console button both work but I heard some sort of metal component inside the tailgate...

Sounds like something just fell apart inside. Probably just a roller or something. If you can't do it yourself, it shouldn't cost too much. Just make sure you stand there and watch, so you don't get ripped off. In fact, if you take the cover off the inside of the tailgate, maybe you can fix it yourself.
