Rear comfort seat not working?!?!?

What's up guys?!? It's been some time:-)) it's a good thing cause the car been good till now:-(((( so I couldn't find anything on this??? Ok my right side rear seat stopped working. The fan and heat also??? The seat doesn't move at all? But that same switch works for the front seat still?? So I don't think it's the switch?? For the guys with rear comfort seats, there a button on the armrest that you hit to control the front right seat so that the rear passager can move the front seat to there likely. Any idea???

On driver's door there's a button that locks out the rear windows in the back. It also locks out ALL electrics in the rear including the seats. It's to stop kids messing about with them.

Make sure the the little green light isn't 'on' on drivers door and try your seats again. ;-)

Ok. Sounds like it could be a faulty 'seat module'.

It's just a direct replacement and no coding needed.

To test it you could swap the rear left and right seat modules over to see if the fault transfers over too.

I think it's in the trunk of the car?? I found one on EBAY, just to see what it looks like. And it's too big to fit under the seats.. I'll open up the panels in my trunk to see if I can find them???

Look at the sticky "Found an interesting E65 Tech Doc". The location of all the modules is given on page 35-37 of the pdf document in post #1.

There are so many modules...

All fuses are good. I checked the one in trunk and glove box. So there one module on each side?

thx for the pictures helped a lot. but the seat switches can't be swaped!!!!! different pin out. there's another module in the armrest that all of the switches goes into in the rear. I'm thinking that module is bad cause what are the chances of two switches goes bad in the same side. the left seat control and the air switch and heater switch are not working at all on the left.
