[Hello!]

Hi! I am the owner of an 02 Celica GT-S six speed. I have done quite a few mods on this car and am a member over on newcelica.org

[power windows]

I recently aquired a 1990 celica gt,

great car with some minor hiccups, one of which is the passenger side window doesn't not roll up or down

Im not sure where the best place to start is.

any ideas ?

Thanks in advance

Is it a power window? If so check the solenoid. This will be the best place to start.

ive been looking around on these for alittle while but havent been able to find much for info, is it worth it on a gt to get one? is it going to make a difference?

These are very bad for your car, it underdrives all of the cars other systems and can lead to very bad consequences. I know on the gt-s it will wear out the oil pump and your engine will not get any oil. If you really want to get one, go with one that is lightweight only, not an underdrive.
