this person's problem is solved, but for anyone else....
I had the same problem- window would go down but not up. the motor was working, I could hear it running good and strong. ok, now listen.. im not a mechanic. so I cant name parts and whatnot. car parts I cant identify are thingamabobs, doohickies, gadgets, and contraptions.
anyway, after I figured out how to take the window motor out, I plugged it back in and hit the switch. the metal gear on the motor that grabs the metal gear doohickie that is attached to the bottom part of the glass that makes the window go up... that metal gear on the motor was spinning so I couldn't understand why it wouldn't work.
so then I took the motor apart- and it was full of grease and plastic contraptions. (if you take your motor apart- pay super close attention where everything is- and watch for springs that may fly out of it!) among the heavy grease that was obviously chunks and bits of plastic from the gears. the plastic parts had worn on one another and became stripped. I tried several things to make it work again... I wont waste time with what DIDNT work...
here is how I fixed it:
I took all the round shaped plastic gear parts out of it, and the metal gear that you can see on the outside part of the motor. took them to the kitchen and scrubbed off all the grease til it was clean and dry. then.... I applied hot glue and glued them all together into one piece. I put the motor back together the way I found it (after I located the spring that flew out of it) and re-installed it in the door. SUCCESS! (after all day of trial and error).
(there is a gear in there shaped like a corkscrew which turns a round gear that you will need to remove in order to glue it to the other round gear. neither of those gears should be stripped or broken, but if they are, I guess youll have to get a new motor unless some kind of rebuild kit is available?)
now, if you replicate my repair job, when you take your motor apart and you see the round shaped gear parts that move the metal gear on the outside of the motor- you will notice that these plastic parts are designed to work like a ratchet so that if you continue to roll up or down the window beyond its limits- it will ratchet so the motor wont strain and nothing breaks. when you glue it- make sure it looks just like it did when you took it apart- with the round metal plate (that screws secure it to the rest of the motor housing) between the plastic gears and the metal gear. and don't use too much glue. don't let it ooze all over the place.
so if you replicate my repair, don't roll your window up or down too hard. I didn't want to risk finding out what would happen if I did... you shouldn't either. im just careful not to roll it up or down too much- and ive had no problems since.
good advice for a cheap/free repair.... IF the motor works
