Passenger window rolls down, not up— switch is good

[PlayingWithTBI]

It appears the switches in the left side are different than the switch in the right side - different polarity so, swapping them wouldn't work.

Looking at it further, the switches may be the same PN, just wired differently in their sockets. I remembered the door locks are like that too. Leave it up to GM to make them look different so it's easier draw the schematics.

Yep. I tried to put my drivers side lock switch on the passenger side & didn’t work. I was trying to figure out why my keyless entry wouldn’t unlock the passenger side. Bad switch.
