2012 Grand Caravan. It has been modified with a 9" dropped floor for wheelchair use.

The drivers side sliding door is completely dead. Lock works but it will not power open or close (using handle or remote) and the power window will not work. I can still open and close it manually.

Looks like there is just one fuse for both doors (you can check me on this) and the passenger door works.

Any idea where to start looking?

Does anyone have a wiring diagram?

It may even be in the "extension" that the factory did to drop the floor.

Is there one power feed (or maybe one ground) for the entire door?

Door does not get used much as the wheelchair ramp is on the passenger side door.

Thanks .... Mike
