I have a 2003 EB 4x4, neither of my rear windows will come down. At first I thought it could be a bad "child safety switch" from the master window control. I removed the switch and found 12dcv at the "safety switch" I tried to bypass the "safety switch" by connecting the three wires in different ways. Found that two wires were hot and got burned. But still didnt solve the issue. Front windows work fine. I dont want to replace the master switches until I have put my thumb on the actual issue. i have not been able to locate any articles on both rear windows failing at the same time, which seems suspect to me and leads me to believe it is the master switching mechanism. Any thoughts on this is greatly appreciated.
