Relay maybe .Doesn't look like a relay is involved for window . Looking at a wiring diagram an using a volt meter to test electrical circuit would be the way to find the problem . Do you know how to test automotive electrical circuits ? How to read a wiring diagram ?
Midgate Components
The midgate consists of the following components:
• Midgate window switch
• Midgate latch release switch
• Midgate window regulator
• Left midgate latch
• Right midgate latch
• Midgate latch relay
• Midgate 25-amp window regulator circuit breaker
• Midgate 15-amp latch relay circuit breaker

The midgate window is controlled by the following:

Reading a little more from service repair manual i do see a relay , it's part of the window motor assembly . Could possibly be the window regulator . You need to take midgate panel off an look inside . Test electric to the motor while in then .
Midgate Window Operation
When the midgate window switch is activated to Up, battery voltage is supplied to the coil of the midgate window up relay in the window motor, energizing the relay. When the window up relay is energized, the window is driven in the Up direction.
When the midgate window switch is activated to Down, battery voltage is supplied to the coil of the midgate window down relay in the window motor, energizing the relay. When the window down relay is energized, the window is driven in the Down direction.

Hello, before replacing the power window regulator, always check to see if the window motor or the regulator is the problem. Turn the ignition key ON and listen for the window motor,if the window motor can be heard when you move the switch and the window does not move, the regulator is definitely bad, and if the motor does not work, the motor is the problem.This is a common problem for the window regulators to go bad. The cable is probably fine but the plastic piece that the cable locks into i bet is broken. These are not replaceable you will have to replace the whole regulator. Beware of aftermarket ones they are not as good as OEM but they are very expensive at the dealer probably about 250.00 to 300.00 dollars.

Thanks

Your there, unscrew 10mm bolt's that hold window regulator, and two small bolts that hold window to regulator, used something to hold window up, while window regulator is out, most part places will sell this part, it's call a window regulator, there no repair for the cable, assembly will have to be replace.

To remove the window motor on this truck remove the door panel to access the window regulator and motor assembly. The regulator might be riveted in so you will have to knock out the rivets to remove it and replace them with bolts and nuts. Once you remove the rivets lower the regulator and window down to slide regulator out of the channel on the bottom of the window once removed from window push window back up and tape in position to pull regulator and motor out unbolt motor of regulator being careful not to let tension spring on regulator to release real fast it will mess it up. Replace motor and reinstall regulator assembly back in the door on the window and bolt into place. Put door back together.

wow, a lot of work to do.

If you search Google for Ford Focus Window Regulator replacement, you should find a great deal of information. The front doors are different from the rear (sedan, station wagon) doors. I've replaced the rear window regulator and it wasn't hard but the front window regulator is very different from the rear regulator.
