Toyota starlet drivers window stuck shut

[kevinarbury]

Hi there,

Just bought an old Toyota starlet and the drivers window is stuck shut. I've taken off the door card and the switch seems to work because I can hear the motor clicking and can feel the resistance on the moving parts trying to work. Any ideas?

Given the weather, the glass isn't frozen to the window seal is it?

No mate, it's warm where I am

There's a good chance of a tight mechanism or faulty motor

[kevinarbury]

if it's a stiff mechanism how do you free it up enough to start working other than oil as I've sprayed loads in there.
The motor is getting quite hot too with pushing the down button loads
Cheers,
Kev

You can try assisting it downwards with your hands each side of the window while someone operates the switch to the down position

[kevinarbury]

Yeah already tried that, unfortunately made no difference.
The motor was getting quite hot but that makes me think it's something other than the motor as it getting power....very strange!

Oil rots rubber, causing it to swell. If the glass is pinched between rubber seals this can make the problem worse. You can get silicone based rubber lubricant which is the stuff to use.

Bad do
You need to remove the motor from the mechanism and then try moving the window up and down, you will then know if it's tight, you can also possibly strip the motor down and see if it's burnt out, you will definitely be able to power the motor while it's away from the mechanism to see if it operates, the thing is even if it does operate you won't know if it's got enough torque and that's why it's a good idea to take a look inside the motor

The other option is to remove the motor and once you are happy with the mechanism refit the motor and operate it, if the mechanism is free and the motor wont operate it you will know that the motor is not working correctly

There is always the chance that water has got into the motor and it is siezed
