Other problems/solutions to get the passenger window fixed? Module Mercedes Part # 129 820 24 26 needs diagnosing if it is not a relay? Best least expensive fix for this part? Going to unhook battery to reset module/sensor codes...have to also enter radio code...will this effect window operation? Can this be done without effecting other settings for engine performance? Are there additional window switches other than the center console ones? Where? Is there a window lock out or child safety setting switch? Where?
