You could have a switch malfunction (try raising it with each side's switch - one at a time) but most likely it's a wiring problem. Very common. Remove the door panel, see what you find (possible shorted wire) and go from there.

The fuel filter is under the car; located just ahead of the gas tank toward the passenger side. It's a canister type. Release the gas cap (pressure) before changing or you'll get sprayed with gas.

The PCV is located at the very back of the intake, not readily visible. Use a strong light to locate it - it's in the center of the engine - or just go by 'feel'. Do it on a cold engine. The PCV should be removed as a unit: valve, grommet and screen. Go to a Ford or Mercury dealer and ask for the 5.0 PCV replacement kit (about $10.) A bit of a PITA to change but worth it.
