2009 Chevy Tahoe Driver's window switch problems

[Tahoe_SSV]

So, my Driver's window switch isn't working properly. It will roll down the 2 rear windows, but the 2 front windows...Nothing. The passenger switch works fine and if I put passenger switch on drivers side it will roll window down. I took switch apart and cleaned the switch housing, the pad, plungers and all the contacts. That didn't work. Any ideas?

If cleaning didn't work, replacing is the next option I'd pursue. Those Bosch switches are prone to moisture ingress and corrosion.

If you do replace it, try to keep it from getting wet - drive-thrus when raining, etc.

+1 to what @intheburbs said. Super easy to replace but you'll need a Tech 2 to program the new one to your truck.

He can also roll the dice and try to find a used switch from a a similarly equipped truck and it could plug and play without the programming. I was able to do this finding one on eBay.

My drivers side switch will operate all windows accept for driver window. If I put passengers switch on drivers side it will work. Do I have to replace the whole unit? They are ridiculously expensive. At least 100 bucks.

Are you sure it's not the regulator?

it works with another switch so that would be the switch

never had a door wire harness go bad, it's always been the switch/regulator/motor
