Need some ideas to figure out a window problem on my 2000 D2. The problem is with the front passenger window.
It will not go up or down. Driver side ft works fine.

I have swapped the front window switches. Pass-side switch works the driver’s window, driver-side switch does nothing for the pass’s window.

From what I think I see on some diagrams, there is one fuse and relay(?) for the front windows and that the control of the front windows goes through a bcu.

Assuming the fuse and relay are good, and the driver ft window works with either switch, would that point towards a bad pass-side window motor? Or could you still lose control of one ft window and not the other with a bad bcu?

Thanks

Usually the motors don't go bad. I would think switch.

I've had 2 motors go bad, but with those it would at least try to go up.
Next thing would be to pull the connector off the motor and see if you are getting power to it.
Another thing to try is put the key in the run position without the truck running. Turn the dome light on and try your window. Do the lights dim? If so, at least the motor is trying and you may need a regulator and or motor.
