so all four of my windows ahvent been going down for the longest time now, and i jstu recently decided to get it fixed after we got a long streak of way hot weather, so heres the deal. all four of the windows are getting power to them, and i hooked a ground up to the switch in the drivers front door to replace the old one, and now my drivers door and the passanger rear door rolls down. but not the other two. so any ideas what it could be ? is there maybe a bad ground under the hood ? or could it be the master switch ? any help will be greatly appreciated.
oh and it has had some times where the underhood has been really muddy/dirty if that helps. and help once again greatly appreciated
