Factory power window issue

Hoping some of you guys can help me sort an issue I'm having with my '69 Chevelle that was optioned with factory power windows.

All the windows used to work from the drivers door panel but now only the drivers door window works from the drivers door panel. However, the passenger door window and quarter windows all still work from their respective switches.

Would this be a faulty drivers door switch? If so can I just replace the piece in these pictures or is it usually the chrome switches themselves that go bad? Or there's the plastic electrical socket that the pins plug into?

Any input would be much appreciated, cheers.

Re: Factory power window issue

Have you inspected the plug and wiring behind the switch itself? The driver's control "center" is in parallel with the wiring controlling the other windows, so it's not unusual that each respective switch/window still works, but not from the "master control center". Typically the contacts inside burn from use and no longer work, but you'd think if anything, the driver's side switch would go first. That's why I'm suggesting taking a look at the wiring/connector.

Thanks for your reply Joe. I'll have a look at the connector, what would I be looking for, loose/disconnected wires and signs of burning?

Cheers

Yes, check for any signs of corrosion, heat, discoloring, loose connections etc. I don't have the colors off hand, but you could take a jumper wire and short from the "common" power connection to each "up" and "down" connection to see if the respective windows respond, if they do, you know there's something going on with the switch or how it mates to the connector and not with the wiring coming into the driver's door.
