How to retrack drivers door / fix pop up headlights to go up & down again / also has wiring problems at night you gotta hit the dash to get lights to go back on when driving ? Other then that this

The problem is most likely in the window motor. There is a second relay in the door which controls the autodown feature. Whether the autodown relay is part of the switch pack I do not know. Your bill may show a description. Holding the windowswitch overrides it anyway.

You are right about most of the controls being in the door. The source power line does come from the fuse panel under the dash. Many of the Fords have the relays in the door. You have a couple of choices depending on how much $ to spend and what you want to learn.

A glass shop is experienced about disassembly and reassembly of the door. The motor is expensive for its size versus a Salvaged part. The drivers window is the most used on the car. I would consider a new regulator if the motor is replaced. It is a plastic part and now 6 years old on your car.

If you do this yourself you need to block the window in an up position so you can access all the parts. You need a 1/4 inch drive socket set and some wood to place under the glass. Be careful to remove all door panel screws including those hidden inside the trim plugs on the inside door handle. The regulator is additional work.

Good Luck

Your friend is correct, you have a short somewhere. I would strongly suggest taking the car in to be serviced.

while this occurs; do you hear clicking near your right foot area while sitting in the drivers seat? it may be heard very faint (you may have to remove the sound barrier panel under the dash first. Does this problem only happen with "Automatic" lights? Does it happen while in the parking lamps position? I wish to suggest the light switch itself, or the connector at that switch may be loose, or the negative supplying the switch could be loose. But more likely, you should check for a defective BCM, or loose connections to it, located between the lower left of the ash tray area and the accerator petal area (the relay inside on the circuit board may have a bad solder connection to it) ... or the relay inside is bad period.

You may need to remove your door panels (screws are by the door handle, arm rest, under door and side of door) and then peel back the weather film on each door to see what could be causing the issues.. rusted wires, loose connection, broken linkages, seized linkages. I'm not sure what to do with your car since each door seems to be having a different issue, but I would check the locking mechanisms..

Your door ajar switches are located inside the rear faces of each door along with the latches. Just liberally spray a petroleum based lubricant into the door latch areas of each door (one at a time) and open / close the door several times. Once lubricated, your door ajar light, interior lights, and autolocks should function properly.

Good luck.
