Usually, this problem is caused by misalignment of the various parts in the window regulator and/or guide track assemblies.
Another possibility, if the vehicle has electric windows is that some component in the electrical system is maladjusted, or defective.
if manual, window regulator. if electric, check fuses, window switch, window motor, window regulator.
You probably wont. Chances are, if your window doesn't go up and down right, you have a broken pulley in the window regulator assembly. This is common and requires the replacement of the window regulator.
A power window that does not "roll down" in a 1999 Toyota RAV4 is most likely the result of a faulty regulator. The regulator can be replaced by removing the door panel.
If its not working check the connections and if it is working but wont go up and down then the window regulator is broken and will need to be replaced.
The regulator has failed and needs replaced.
you need to replace the window regulator
The window regulator has failed. The new one from the dealer will come with a window motor also.
If it's a window that drops open or a manual/electric window that wont wind down or up, you need to replace your window regulator - about £25 second hand to replace.
I found having a repair manual specifically for your make/model/year a great start. I'm in the same boat and this is what I have found out and will be doing next weekend. First, I had the a screw placed in the regulator to keep the window up until I am able to replace the window regulator. The regulator comes complete with the motor, so what I will do is remove the current regulator have a friend holding up the window has I am doing this so I wont have to remove the window (to skip a step), then just attach the new regulator in the same place as the original.
there might be something mechanically wrong withe the window itself. ie the regulator arm is jamming or needs lubricating.
It is most likely a broken window regulator or bad electric motor. Don't know about the cost of the motor but the regulator will run $40-$70 + labor to install.
It sounds as if your window motor is either going out or the window regulator is binding somewhere. I have heard of people putting a good silicone spray along the window track and that sometimes helps. You will have to remove the interior door panel to get access to the window track. It is what the window slides up and down in. (the left and right side of the window.) Good luck.
