so i went out to my car today and my power window wouldn't roll down. it worked fine yesterday and then all of a sudden it doesn't go down today. wtf. it makes no sense. i tried 3 different switched and i also tried another window regulator and nothing. it will roll up but not down. i makes no sense to me.

 

ok nevermind i was dead set that it wasn't the switch but then i got mad and started to look through a hundred post and found the one that had the same problem as me. so all i did was just open the switch up and then clean out the contacts with a dremel polishing wheel and the little wing shaped copper things and then put it back together and now its fine.
