Problem: Toyota Sienna 1999 passenger side window won’t activate.
Driver side window works fine but passenger side window stopped working abruptly after removing door panel to work on exterior door handle. That was a few months ago - assumed reassembly was at fault, but let it go through winter. Neither window switch (driver side or passenger side) activates the passenger window.
Now it’s spring, windows should open, so removed door panel again: window switch connector was seated and locked into the harness, nothing visible to suggest problem on the connectors. Otherwise, nothing else looks amiss. Reconnected switch with door panel removed - no change.
With switch removed, a grounded test light shows 12 volts in the harness on the blue/yellow wire. There was nothing at any other harness contact.
Tried jumping between the blue/yellow and the other wires one by one. None activated the window. I don’t know how these work, and whether jumping this way, one by one, would power the window, but guessing all the connections must be complete for the window to move.
Since neither switch activates the window, I’m ruling out the switch. Since driver side window (and all other power items) work fine, ruling out fuse. Could be window motor, but the only apparent change was removing / replacing door panel. Prior to that, there was no sign that the motor was failing / laboring, etc. Passenger side door lock switch works. What am I missing?
