Hello Everyone,

I'm having an issue with the passenger seat on my new-to-me 2009 C63. The bolsters and lumbar adjustment buttons on the side are performing, but the seat will not move forward/backward. I checked the connectors and everything appears to be in good order, so I'm stumped. Any insights or instructions?

The control module on the door probably died.

Ok, going to take a shot at this one, there are 2 types of seats, the fully electric that has the controls on the door by the opening handle on the inside and the semi electric that should never have existed on a 75k car, but I digress.

If you have the semi electric, which I think you have, you have the 3 buttons on the side for bolster lumbar etc. You also have 2 buttons on the lower side of the seat that are height and tilt, then you have a manual wheel near the front to raise and lower the front of the seat and then you have a manual lever on the floor that you pull up and can run the seat back and forth manually.

My passenger seat stopped reclining last week. There's a control module under the seat that I think I messed up when installing my fire extinguisher. Try unplugging/replugging the control boxes under there. Same thing happened to my drivers seat the first week I had my car, and that fixed it.

Thanks for the quick reply. I have the fully electric with the controls on the door. :-(

Trying this right now. Stay tuned. I will let you all know what happened momentarily.

My buttons on the seat itself don't seem to do anything, I wonder if that's something to do with the harness? Hmm.

I plugged and replugged all the control boxes underneath the passenger seat. Unfortunately, it didn't fix the issue. Could it be a fuse? Or is that improbable? Thanks everyone for the replies and help.

Could certainly be a fuse, worth a check - there seems to also be a known problem with the relays that control the seats going sometimes and if you search around there are reports of wires under the seats sometimes getting pinched and causing the fuse to blow or relay to fail.

Thanks, Roadkillrob for the great advice. I will read this right now.

SO, I tried all the fuses and nada. Nothing blown. I'm stumped.

Not sure why people are averse to taking my advice, but I refer you to the second post in this thread, lol.

asaud7

I wasn't adverse to taking your advice. I need to figure out where to purchase a controller from. Any insight?

I just checked mine. All other functions work fine, and even incline/recline works, it just doesn't recline past a certain point. My issues are obviously different, forget it, sorry for the hijack (my battery is disconnected, and that should fix it... I think)

Edit: Nevermind, I'm stupid. I didn't realize that the seats won't recline if the rear seats are down. That control module thing still worked for me on the drivers side, but obviously this is something different. Search is your friend, duuuh.

No worries, I get it from my GF all the time...

Mine was replaced under warranty, but contact FCP Euro, they can try to source one for you. They are great guys.
