You need to check Voltage + & Ground - at the Window Motor "2" wiresThe Circuit will be "Reversal Rest At Ground"Switch held in UP:One wire will have Voltage +One wire will have Ground -Switch held in DOWN:The wire that had Voltage + is now Ground -The wire that had Ground - is now Voltage +.
Use of a VOM is needed to testThe way it works:Ignition OnSwitch held in Up positionOne wire will have 12 Volts +One wire will have Ground -
Switch held in Down positionThe wire that had 12 Volts + is now Ground -The wire that was Ground - is now 12 Volts +
