Hi all I’m sure this has been talked about before but my front passenger seat won’t go into the fully upright position I’ve tried the old go all the way down hold for 5 seconds then go there other way and hold for 5 more seconds that didn’t work, no obstructions, tried resetting memory of seat, removed battery, nothing seems to get it back fully upright like the drivers seat goes. So anyone had same issue and if the managed to sort it please let me in on the secret

Maybe pull down your back seats and slam them back into place( gotta push back in pretty hard on the older cars for it to latch properly) if they don't latch all the way sometimes it will limit the front seat movement

May need to be re-synced using Xentry (MB diagnostics) possibly due to low battery condition.

Funnily enough I tested battery today and it was only at 40% but won’t it effect drivers seat as well.

You will have to go for SD reset. I had the same issue with driver seat. I went for a SD diagnosis, they reset the memory and everything is perfect since then.

Hi, have you been able to fix this issue?

erich_aux

Had the same problem. I also had to take it in to a shop so they could perform a reset. Was only a couple hundred dollars.

You dont need to go to a shop to fix this. Just unplug the motor harness behind the seat then push the control forward for 10 seconds and that will fix the issue.

Which harness, there's a few of them ?

The one that is going to the motor. The motor is the vertical cylinder on the side area of the back seat. There is only one wire going to it just unhook that one. Use two small flat screw drivers to do the job. One is pushing out the retaining tag and one is pushing up the pin. DO NOT PULL FROM THE WIRES.

Worked like a charm, seatback goes way forward and back now. Can't thank you enough !! No to figure out why the Aircap doesn't go up, any ideas ?

shotgun_banjo

Not sure what you mean about Aircap.....

Cbb129

I have an E350 convertible, and the Aircap is a wind deflector at the top of the windshield that you can raise up and down to keep wind turbulence down at speed. Mine doesn't do anything when I press the button.

RE Aircap Check the fuses, but the control module is what usually goes on these A207. There is a thread on here somewhere that someone posted some of the details for replacing it. But it does mean the Aircap and top of the windshield area has to be disassembled. Module is $$$$ from MB and may not be available any more. You would have to check, IIRC that poster found a used module off Ebay or some other place.
Good luck with it and post up if you decide to replace. Pics and better write up would be nice.
Also it might be wporth looking into getting the module tested and repaired, if possible.
