Check your fuses, check connectors on both switches for corrosion or wear, try replacing one of the switches.

Passenger side power window on my 03 mountaineer will go down but not up. After a few times turning the key on and off it will eventually go up

I would say the key thing has nothing to do with the window going back up . If it were a power problem , it would affect all windows . They all get B+ voltage from the accessory delay relay , located in the central junction box,under dash panel, LH side .Which switch are you using , driver or the switch at that door . or does it make a difference ? Do you know how to do electrical testing . I would say it's a switch or motor problem for that window . Automotive Electric Window and Switch Troubleshooting Repair Guide

Driver seats mountaineer stop working, passenger power seats work

The next time the seat is inoperable pull the switch out and test it for a voltage signal that should be present when the button in question is operated. The switch is the most common issue that I have seen, but hold on replacing it until the switch is tested.

2002 mercury mountaineer on e window not working

All the windows are on the same fuse, if the other windows are working fine, it's not a fuse issue. I susppect the motor or the window regulator.
With your ear close to the door panel, press the window switch up and down, if you hear the motor and grinding noises then the window regulator needs to be replaced, if you don't hear anything then the motor is bad OR no power is getting to the motor. either way you will have to take the door panel off and to fix.

My 1999 mercury mountaineer driver side window went down and will not come back up all the other window work

I'd look at the window regulator.
If you can hear the motor turning then you're gonna need a regulator.

If you throw the switch with the dome light on and the light gets real dim...then ya might have a bad window motor.

These usually come as a complete assembly both motor and window regulator.
They run about $60 on Ebay

Hope this helps...
