I just got an 85 Rx-7 and the power windows are not working very well, the passenger side goes up about half way only and the driver side i have to go up and down for a while and it goes up really slowly

any suggestions on how i can fix this myself

 

I pulled off the door panels on the inside and sprayed some WD-40 on the drive gears and such....
Helped a bunch.

Silicon spray would be another good way to go

 

well it sounds like the passenger side came off the track. just pull the door panel and put it back on from the front. if it happens again, theres a screw which holds the track in place, and can be moved right to make it closer to the glass.
