I have read questions and answers about the problems everyone has been having with windows not working, and have watched the videos of the same thing. I have checked everything I have read and watched and all of my wires are good, fuses good, have 12volts in plug, my soldering is good on the electrical board, but still no luck on windows working. They don't work from master switch or go down from individual doors. Can someone please help? My wife would like her jeep back. It's been sitting for a year and a half because I can't get windows to go back up. Thank you
