I have a 2001 Chevy Express 3500 15 passenger van. A few months ago the power windows started going out, as in the would not work but if I opened the driver door just right it would work. Now they have stopped working, when I press the switch nothing. If I open one door the Interior Light control Module clicks under the dash(found what was clicking) If I open both doors the windows WORK normally but only if both front doors are open. Sounds like a short to ground or bad switch somewhere in one of the doors but not sure. Oh and if when I open one door I try the switch, the module clicks and the interior lights go out while I have the button pressed. Any help would be appreciated, Thanks.
