driver side aster window control panel

my drivers side window controls wont open the passengers rear window, but that window will work from its own control. where should i start testing the connection?

Likely the up/down switch on the driver's side controls for the affected window.

You can pry up the trim around the switch and pull the wiring up some to inspect it, though this is easier to do with the door panel removed. The issue could also be in the switch itself. Might be easier to just get a replacement switch from someone parting out on here, or even just the entire driver's side control panel.
