Hello, the other day i was brushing snow off my car and some of it landed on the master power switch where i control all my windows and mirrors on the driver side. I cleaned as much as i could off of the buttons and stuff, which today i go to roll down the windows and move my mirrors around and when i go to roll them down and up it isnt working. The only buttons that work are for the back passenger windows. Can someone tell me what might be wrong or what needs to be replaced? Thanks
