Passenger side window stopped working with either switch, but the driver side window is working, so that would rule out the fuse or the relay, right? I installed a new switch, first on the driver side with no response, and then on the passenger side, still no response. What else could it be? Do you need to have a working switch on each side for the passenger window to work?

Thank you folks.

Just fixed it. Took apart the bad aftermarket switch and fixed it. Both switches working and the window operated. Apparently they both have to be good and both installed.
