So i have been experiencing my power windows only work on the drivers and passenger side going up and down. The rear(s) only goes down. So far ive uninstalled both rear door panels to remove the switch and test it with a test light. Here some results. With the test light ready we tested the rear switch(s) going down, They both have power & ground. Now when we tested them going up, we only had power, no ground. Next on my list is to remove the master switch and test that aswell. So I get power and ground on the front 2 going up, but on the rear i only get power no ground going up, any idea's??? Im going out today to remove the door jamb boot on the drivers side and try to tug on some wires to see if i can find any broken ones. Thanks Guys & Gals.
