The sunroof quit working, usual Ford sunroof problem (Sunroof guide jaws). I replaced the same parts on my 2019 Super Duty, so I was familiar with the task. Anyhow, as I got into the replacement of the jaws, I realized that the cable that moves the jaws was broken from the bracket. So, I replaced the whole sunroof frame, swapped the air deflector, shade and motors and reinstalled the frame. I reconnected all the electrical plugs and put the headliner halfway back up. Before I finished installing the headliner, I wanted to verify that it worked, but it did not. I removed the motors from the frame and still could not get anything to move. I have tried initializing multiple times but that doesn't do anything. And yes, I have checked both fuses the one for the moonroof and for the moonroof logic (#23 and 27) even replaced with brand new fuses and still no action. Any help or Ideas would be great.

Did the old motors work? If so, there is a startup procedure that must be performed, I have included the sunroof motor replacement instructions as well in the diagrams below.

Power Roof Opening Panel Initialization
Initialization

image 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.

NOTE: The roof opening panel motor must be initialized when repairs are carried out on the roof opening panel system, including: any time the roof opening panel motor has been removed, the roof opening panel glass (fixed panoramic or front sliding) has been removed or adjusted, or if the roof opening panel frame has been removed.

NOTE: Carrying out the initialization will initialize both the roof opening panel glass motor and the shield (sunshade) motor.

Place the roof opening panel sliding glass and the shield in the closed position.
With the driver’s door closed, place the ignition switch ON and wait for the overhead console lights to turn off.
NOTE: Steps 3 - 4 must be performed within 3 seconds.

NOTE: Steps 3 - 5 are to set up the overhead console to accept roof opening panel switch inputs to be held for up to a maximum of 150 seconds. Normally, the overhead console will consider the switch stuck after 30 seconds and ignore those longer inputs from the switch.

Press the left map light switch once turning the lamp on.
Without pausing, press and release the right map light switch four times ending with the lamp off.
Without pausing, press and release the left map light switch once turning the lamp off.
NOTE: Step 7 must begin within 2 seconds of releasing the switch at the end of step 6.

Press and hold the sliding glass closed switch.
The sliding glass will stall at the hard stop (closed position) and then move to the vent position.
Then the shield will move to the fully open position.
Release the switch and immediately begin step 7.
Press and hold the sliding glass closed switch again.
The sliding glass will move to the fully open position and then return to the closed position.
Then the shield will move to the fully closed position.
Release the glass close switch and verify proper operation.
If the roof opening panel does not operate correctly, repeat the procedure.

Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.
