Dynamic Seat Pump
Guys and gals I have a small problem with my car. Just recently, the mult-contour seat, dynamic seat and the pulse for the 2 front seats stopped working. I searched online and I thought great my pump went out. In any case, I was going to order the pump until last night I decided to sit at the rear seats. I adjusted the lumbar and to my surprise, I could hear the pump working and the rear seat lumbar bladder was filling with air.
Is this a sign of a bad pump? I don't think it's the lines but if it was, what are the chances of the driver and passenger lines getting disconnected or broken at the same time? I get the flashing lights on pulse for both driver and passenger seats. Bummer, at least the soft close function still works since from what I understand it is also powered by the same pump?
I tried disconnecting the pump and plugging it back in and the pulse button would stay on without blinking but the bladders will not fill air at all. After a few tries, the pulse will start blinking again. Sigh...any insight would be greatly appreciated.
On the other hand, I hope to see some S AMG's next sat on Laguna Seca! Thank you in advance again

It's a line somewhere in the system. I had the same issue and it ended up being a line at the pump that had popped off. It looked like it was connected but it wasn't. Pump is on the driver's side in the trunk, behind the side panel.
