so on my 98 corolla my power windows sometime takes forever to close. it will go down smoothly and i noticed it will stop short to being all the way down and when i try to bring it back up it will go up but slowly then stop. id have to wait a couple mins to like let it charge or something lol for it to go back up id have to pretty much like play with it just for the window to go back up. could this be the window regulator or the switch? i want to figure this out before i just start buying parts. can somebody help me please
