Roadtrek Seat Side Switch Function

[LaneG-iRV2]

Looking over my 06C210P (Roadtrek) i noticed that there are switches on the side of the seats. But they don't look like the switches mentioned in the Chevy Van owners manual.
Here is the Chevy Owners Manual picture.

And here is a photo of the switch on my seats.

When I toggle the one for the passenger seat I hear a motor running but there isn't anything moving. The one on the drivers side is dead, I don 't hear anything.

I'm sure that someone can help me out. I can't find anything about them in the Roadtrek owners manual either.

The one on the side is the seat back bolster adjustment.

If you had a factory power seat the control would be in the front between your legs. I converted our driver's seat to power and removed the rotator.

That is probably lumbar adjustment.
