The part I replaced moved the seat backrest forwards and backwards.

"My one seat won't go down and im trying to figure out if this is why."

if you hit the switch and nothing happens at all, like mine did, i would think it's the motor or the switch itself. I think the one that moves the seat up and down is the motor right next to the one I replaced. "Actuator vertical seat adjuster rear" as described on realoem.com. part # 67 31 8 357 058. I assume it's a pretty similar installation process.



if it is the switch then it'd be the part I described earlier to mr. zottyzot

Of course I'm probably wrong again and it's something completely unrelated. I have the same answer to everything because this is really the only thing I've done to my car since I got it, so this is everything I know about the car. That and how to snap in moldings. but I don't think moldings are your problem.

There are two separate gear boxes for each of these components. Look at your Bentley section 520-4. You should be able to hear the motor on occasion to know it's the gear.

This was going to be a priority for me as the PO had the seat laid back in too cool of a spot for this old guy. I was fortunate to be able to put a little pressure on the seat back one day and get it to move while actuating the motor.

I still plan on doing the gear change though.

I'll be pulling the drivers seat out this afternoon. I'll post pics of what I find.

This is the guts of the gear box -
