Hi,
First post! I took delivery of a 2011 Viano last week. The kids were all excited and loved how it played a few little tune when they opened the rear sliding doors. Since then however, I've got no power to the sliding doors. The red light on the pillar doesn't light up and neither do the two buttons on either side of the dash switches. I've searched everywhere trying to find someone who's had a similar issue. Any ideas? I've checked all the fuses which all look good.
I'm in New Zealand and this is a Japanese import. It's only done 44k kms and is really tidy apart from this issue with the doors.
Any help would be greatly appreciated.
 
Have you checked the fuses? Fuse Block F35 27 & 28 both 30A? Here are the diagrams which appears to be for all Vianos including the Japanese market.

 
I guess that didn't work Chester'
I suggested the same on t'other side.

No lights on switches broadens the mystery as I only see supply from those 2 fuses. Next would be the SAM imo.
 
Think I'd take it to either Merc or a good indie with Star, the electric sliding door motors & set up are expensive. So I'd get the fuses checked 1st but if that doesn't work go to the Indie

Thanks for replying. Yep, that was one of the first things I' tried. It's a right head scratcher!

Thanks for responding. I'd read about the SAMs and was wondering if it could be that. There's an auto electrical place in town, I'll run it down there next week and see if they can find anything.

Thanks. I'll take it to the auto electrical place in town and post back here how it goes.
