2009 VE Commodore Drivers Rear Power Window Not Working

[279Henry]

Hi just helping someone with their driver's rear door power window not working, we replaced the switch with no luck, window will open & close if operating from master switch up the front but not from the door itself. Door did have blockage in drain holes not sure for however long but seems to have a lot of water came out once unblocked just wondering if that may have contributed to the issue or maybe broken wire somewhere in door, any help will be appreciated. All other doors work from master switch or door itself, no problems there.

The moisture might indicate that there’s some corrosion or poor contacts in the plugs.
Disconnect the negative terminal of the battery.
Id be pulling the door loom connector and spraying some “CO Contact cleaner” in the plug. I’d also be doing your best to clean the contacts in the window motor plug. A piece of scotchbrite glued on a small skewer or similar might get in there enough. Spray out the plug with the same stuff. Make sure it’s dry and plug back in. Reconnect battery and test.

Also make sure the window lock button isn’t pressed on the master switch. That stops kids playing the classic game of “window goes up. Window goes down”
