Only the passenger side front window works, and only from the passenger door control. That leaves three windows, all operated by driver, that won’t work. Tried replacing entire armrest/control panel from junkyard. No go.
The good news, is it doesn’t work, as intermittent connections are the worst. So it is time to start tracing voltages to see where the connection is lost. I don’t know the car and model but the wiring through the chassis to the door is a weakness in many cars.
