Where is located the sliding door AJAR switch on a Windstar 98?

I look all around in the sliding door, I can't find the switch. Nor in the service manual.

Because the dashboard indicate that a door is not closed, and the problem is the sliding door contact switch. Because when I open this door, it doesn't chime.

It's annoying, cause I was obligate to remove all the courtesy lamps in the van. If not, they don't turn off.

On my '99, it is the single switch at the rear of the door opening ... mounted in the body.

Thanks for your help. But it was not in the body in my 98.
I look in another Ford manual, it's in the door latch, inside the door.
