The passenger seat is dying off slowly. First its the back/forward option, then back of up/down option, then recliner. So the only thing the seat is doing now is moving up and down in the front and the head rest.
I thought may be motors but the seat was so far back that the back bolts were covered. What a bitch it was to take the seat apart to move it manually forward so I could undo the back bolts. I am so chaffed I f*&%^£ did it though. :bannana:
Anyhow, here is how I singled out the problem.
Passenger seat:
1) Removed the motors and tested on the driver's SCM using driver's seat switch and they all work perfect. So motors are fine.
2) Tested driver's SCM on the passenger's seat using passenger's seat switch, no response at all…dead.
3) Tested passenger's SCM on the driver's side, using driver's seat switch, no response…all dead.
4) Fuses 1 and 38 are all in good condition.
5) No wires are chewed up.
Questions:
1) Do driver's and passenger's SCMs differ? i.e. they cannot be swapped to substitute?
2) All I hear is clicking in the passenger's SCM. Does it mean SCM is failing or is it worth checking the passenger seat switch?
3) Where can I (if I have to) buy reasonably priced SCM but not from Mercedes dealer? Serial: A 203 820 16 26
