S55 amg - power seat don’t work but heat/cool does work

So my power seats stopped working but heated/cool work fine. Fuse is not blown. I saw someone say something about unplugging the connect I’m assuming is under the seat and then plugging back in.

The car has pneumatic (PSE) pumps that go bad. Either that or there's a leak in one of the lines to the seats. Do any of the seats work?

Pumps are available. Lines are a science project.

Yeah but the dynamic and massaging features work fine. I’m thinking it might be the switch. All the other seats work fine.

OK, your original post wasn't clear. Everything "power" in the seat works except adjustment? If that's the case, then yes the door modules are known failures (for obvious reasons). Also available on ebay.

Not to hijack the thread but I'm having a similar issue. My power seats are working fine as far as adjustments go, however i have no Heating/cooling and no dynamic functions. I am getting lights on the door panel from both heated/cooled, but nothing working on the seat, both driver and passenger.

Just to confirm, these are totally separate from the HVAC system, correct? I also currently do not have heat/AC, and i believe that to be due to a bad blower motor (Which I've ordered)

What other options can be explored to resolving this issue? Possibly a bad vacuum pump module under the seat?

I have also double checked all of my fuses and everything checks out there.
