Ahhhhh, I am assuming that your power windows have had a crap ??????
Ummmm I dunno of any places that can fix em, but if it helps, the EA-EL Power Window winders are all the same, and will fit each model.
You can get the whole power window winder assembly from wreckers for around $70-$100.
Ford Genuine sells em for round $200.
The EF/EL Winders are non servicable. (I.E. the motor is sealed, and riveted in to place.)
To replace the Winder will take you round 1/2 a day.
The hardest part is removing the Rivets, that hold the winder in place.
If it helps, there is a doco written on adding power windows to an EF/EL. As I said though, the Mechanism is exactly the same, its just the Switch gear, connectors, and Trims that differ between the models
