2009 Chevy Tahoe Driver's window switch problems

[89Suburban]

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.

My used one I bought a year ago was 90 bucks, I feel you. And I had to ship it in from Texas junkyard.

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

Passenger harness is bypassed from the previous owners that’s why my power door locks won’t work unless I hook the jumper wires into power again.
