yea i know what it is..what you gotta do is take apart the switch...it comes apart fairly easy. take out the master switch and try to remove the black part(the black switch button)..you have to clean the insides of the switch itself. if you can get to that then you will see the inside has like 2 metal lil pieces. one of them controls the window going up, and the other one going down. take a screw driver and scrape the crud off of it. make sure its scraped good so that it will make a connection when you hit the switch. see the reason it goes down and not up is that there is dirt in between keeping it from making the connection for going up. its kinda complicated.. so il try to get picz for ya. you dont really need to go buy the whole master switch. in most cases thats what is wrong and people end up throwing out the whole switch! it happend to me since when i bought the car it was already like that...so i was thinking to myself and gave it a try and sure enough thats what it was..just a lil dirt.
