Dynamic Pump Fix
So my dynamic seat pump failed now if yours is not working I'll give you a few tips on how to fix it. I know a guy that works in a Mercedes dealer ship. He's a tech and I asked him. He gave me a motor that he had laying around and told me that it would work but I needed to take the whole pump apart which is fairly easy. Before you do this, if you hear your pump turn on then there's a piece inside that might be leaking which is easy to fix also. First thing to do is remove the clips on the plastic strip there are like 5 clips then pop each side out from the top. Then remove the plugs for the lamps on each side.
There are 2 tork screws. Remove them. There are also 2 clips on top of the left side carpet. There should be a gray pouch. Remove the 2 lines and the power plug. Sqeeze the box ( you should be able to pull it apart). Once you pull it apart there is a board on top. Unplug the board ( the motor and the board should come out together. There's a second board on the bottom screwed in by 3 screws. Look at the center of the board you should see a round piece. Check to see if the piece is seperated from the board. If the piece is loose snap it back in. I used some hot glue to seal it back up. If it is not leaking and the motor is bad, then the motor inside needs to be replaced. I will add pics later.
