How To: Power window regulator replacement on 07+ Expedition

[cstanley44]

Hopefully this can help others fix the same issue themselves. Its not that hard. Took me about an hr, and that was while baby sitting my 5 year old as she played in and out of the truck. A couple months ago I put down the passenger window and heard this horrible crunching sound. And the window stopped. I could still here the motor. I put it up by hand but it would fall while driving. I played with the switch and managed to get it to go up and left it there till I could get the time to fix it. I got the new regulator from Autozone, approx $150, does not come with a new motor. I have the factory service manuals so I did my homework and attacked it yesterday. To remove the door panel Remove the screw cover by the door handle with a small screw driver/hook Remove the screw Remove the door handle cover, it just pops out. In the door pull, there are 2 screws down in there, pop the cover with a small hook, and remove the screws On the side of the door panel (rear edge above the latch assembly), there is a small round cover with a screw inside, remove that too. Remove the two screws on the bottom of the door panel. Pry out on the top point (where the small speaker is) to disengage the clip, then the door panel should lift straight up and then off the door. It hooks on. Don’t force anything. Gently work it and it will come off. Unplug the wiring for the tweeter, door locks and windows You’re now looking at the door with no panel Remove the speaker, disconnect the wiring Take your time and pry off the weather shield, pull by the glue, not the shield and it should stick back on Remove the door pull mount Remove the door handle Gently pry up where the top pin is engaged, and rotate the handle down and out Disconnect the cable Now is when you unbolt the glass from the regulator Go back to your door panel and remove the power window switch. There are 4 hooks holding it in. Disengage each hook while putting pressure on the switch to push it into the door panel. Once all 4 teeth are unhooked it will pop out. Hook up the power window switch. Key in Acc position. Lower the window about 6” so you can see both clamp bolts on the tracks. Loose the bolts (don’t remove) When the bolt is loose you can push on the bolt to work the clamp loose Once the window is free, push it up so its closed. I used some 2” painters tape to keep it closed. Now’s a good time to disconnect the battery. Remove the rest of the wiring including the power window motor and side air back sensor. Work on the bolts in this order Remove the yellow numbered bolts Loosen the red numbered bolts (Ford calls the red numbered bolts – hanger bolts They are able to come though a larger hole and slide into a slot to hold the regulator in place while you are installing the rest of the bolts.) The regulator should be loose now. I found it easiest to move it down into the door, then towards the rear. Then rotate the front of the regulator up and out. You now have an empty door Put the regulators side by side and move over any clips, the air bag sensor and the power window motor. Tracks are greasy so don’t make a mess or drop it. Connect the battery Test Re-Assembly Basically reverse all the instructions. Put the window switch back in the door panel Put the new regulator in the door and mount it on the hanger bolts Secure the remaining bolts Take the tape off the window, and let it down into the clamps Tighten the clamps Connect the wiring (power window and air bag) Put the door latch back on Install the weather shield Door pull mount Speaker Wiring And the door panel (don’t forget to put the power window switch back in first) This new regulator works much faster than before. I should have known something was wrong or about to break. I went ahead and took off the driver’s door panel too, as that window seemed to be slow. The regulator tracks were dry! I added some grease as best I could and sprayed some lube on the cable as I cycled the window a couple times (there’s a opening near the power window motor where you can see the cable moving) Now it too moves much faster! NOTE: If you’re doing the drivers door with the auto switch (or either passenger or drivers on a navigator) the manual mentions an initialization procedure. I guess so the motor knows what’s up and what’s down. I don’t know what this procedure is, I assume its something a dealer needs to do.

First off GREAT write-up

Second, here is my contribution to this thread.

Window Motor Initialization

NOTE: Initialization is required to learn both the full up and full down positions and the profile of the glass as it travels through the glass channel. Once initialized, obstacle detection is enabled. This procedure is only required for Navigator (LF and RF) or Expedition (LF only) window motors.

NOTE: The window motor must be reinitialized whenever: the motor is removed from window regulator drum housing, a new motor is installed, a new window regulator is installed, new window glass is installed, glass top run removal or installation is carried out or when carrying out any operation in which grease or lubricants are applied to the window system. All window components (window glass, window regulator, window motor and glass top run) must be installed and tightened to specification before carrying out this procedure. Refer to the De-Initialization Procedure prior to performing the window motor initialization (unless a new motor is being installed).

NOTE: A new (or de-initialized) LF/RF (Navigator) or LF (Expedition) window motor will not operate in one-touch up or one-touch down mode until initialized. If a new LF/RF window motor has been installed, proceed to the Window Motor Initialization procedure in this section.

NOTE: Excessive bounce-back (window reverses direction with no obstructions present) may indicate that a de-initialization procedure may need to be performed.

De-Initialization Procedure

1.Start with the ignition key in the RUN position and open one front door.
2.NOTE: Steps 2 and 3 must be performed within 8 seconds.

Turn the ignition key from OFF to RUN 5 times.
3.Press the window control switch to the one-touch DOWN position (second detent) and release.

Window Motor Initialization

WARNING: Keep objects and body parts clear of the glass panel when carrying out the initialization procedure. During the initialization procedure, the glass panel closes with high force and cannot detect objects in its path. Failure to follow this instruction may result in serious personal injury.

4.Start with the ignition key in the OFF position and with the LF/RF door open.
5.Turn the ignition key to the ON position.
6.Activate and hold the window control switch in the one-touch DOWN position (second detent) until the window glass stalls for 2 seconds at the bottom of its travel and release the switch.
7.NOTE: After performing this step, wait a minimum of 3 seconds before operating the window control switch or ignition switch.

Activate and hold the window control switch (with no interuptions) in the one-touch UP position (second detent) until the window glass stalls for 2 seconds into the glass top run and release the switch.
8.Verify correct operation of the window by carrying out the one-touch up and one-touch down features. If the window does not operate correctly, carefully repeat this procedure.
