99 camry rear driver side window came off track.sounds like motor still working.how hard to repair or costly to have done.

yes they all share the same fuse. sounds like the window motor has failed.

I just did one on my Chrysler. May be quite different, but I'm suspicious that the track was creased or the fur damaged in some way when you had the original problem, or the track is not secured tightly to the door frame. The regulator keeps the glass pretty even but if the window binds on a crease, or whatever, I guess it could get jammed and slide out the crease instead of up the slot. Good luck. Those accursed things are frustrating work in hard-to-get-in spots!

The sunroof motor is located under the roof liner above the center of the rear seat. You will need to remove the headliner in order to access the motor and or track. Do you feel you're mechanically inclind to remove all electrical, sunvisors, side roof handles side trim etc. If not than repairing the motor or track maybe beyond your scope of work. If you are let us know and once done you can proceed to the next step.

No won't be fuse. My guess is there is something faulty with the main controller. You could probably verify this by trying the switch on right rear passenger door. If it works there then the problem is at the main controller in the driver door. Could be a loose wire or the switch itself is broken.

A car I owned the left rear window did that. I could pull it up by taking a hold of it while another person held the switch. They told me the problem was the track was made out of plastic and it had broken. They had to replace the track. Yes it was expensive to repair but is ok now.

the window motor basically the set up dat make it go up and down behind the door

What you have could be one or both of the following:
Dirty/sticky window tracks, or a window motor issue.
What I would do before you take it in: Get some 100% silicone spray, lower the window, and spray the lubricant down inside the door, on the rubber strip that the window travels in. Run the window up & down to get the lubricant worked in. See if that helps.
What is happening here is this: There is a thermister built into the drive motor, and when the motor gets a little too hot (working too hard, with dirty window rubbers), it opens, like a circuit breaker. When it cools off, the thermister contacts close, and the window works again. 2 things cause this: Dirty window run rubbers, or a motor that is beginning to fail.
Hope this helps. Feel free to comment back for more info...
Thanks for choosing FixYa.

I would not consider that issue normal. Camry window motors are quiet.

Sounds like worn out motors pulling lots of amps to do the job in all thee cases, especially if the other windows are okay.
You can, if you're patient and cool, ( or know somebody who is...) swap the left rear window motor with the driver window motor.
My left rear was factory-new because nobody ever rode back there.
You have to use a motor from the same side, and the driver motor has to go into the left rear door
because it keeps the window up.
Be patient, take your time, allot and allow a complete day to do it and when it's done write a check to yourself. You'd have to write it to somebody, right???
