Rear passenger windor doesn't go up on 2002 Mercury Mountaineer

The rear passenger window will not go up. Previously I had to open the drivers door and press the button for the window to go up. Now this is not even working.

Sounds like it could still be a switch issue. The master switch may have failed on the drivers door.

The proper test - for you or a technician - is to remove the right rear door panel and check for power and ground at the motor. If there is power to the motor and it doesn't work - then you need a motor. If no power is getting to the motor, then obviously you have a switch or wiring issue somewhere. I suspect the switch issue based on your question.
Thanks I will have a technician check this out for me.
