Ford moonroof problems

2018 Ford Expedition Max XLT 3.5L (T) 10-spd (10R80)
Moonroof And Shade Inop

Replaced moonroof frame and both motors all OEM. (Both motors were working before replacement, there was a broken part in the track)

Simple installation but nothing works now. Seems like no power to either motor. The manual briefly mentions that both motors communicate via the K-bus, and if there’s something wrong the roof will not work.

suggestions are appreciated.

I would check the fuse that provides power, and see if it is good, check your connections, make sure that all connections are properly seated.

That’s how i found out it wasn’t working. First thing the process requires is to close the shade and I couldn’t close it.

Service Info for that job is vague. I believe that the shade and panel need to be installed in the closed positions to allow the initialization to begin. It looks as if the process will not even begin until the system sees the beginning points. Since both motors have anti pinch capability the start point is important.
