W126 Seat Switch Compatibility Question...
I have a 1982 300SD, and need a passenger side seat control switch. Can I use the seat switch, from the newer W126 based cars? ( the one with the memory function, and 1&2). Of course, I neither expect, nor want the memory function to work.... Just the basic func. that comes with the 81-85 W126. Will the harness fit? Will the trim, etc, fit ???? Thank you in advance.

One of the seat switches in my car is the newer type and it works fine. What is wrong with your old switch?

The old one failed in moving the seat in one direction, and also for the back rest. I verified ( by powering the motors manually) that the motors and flex cables, etc, were all operational ( in other words, powering the right motor produced the correct action), so the problem was narrowed down to the switch... Removed the switch, and in trying to 'look inside', for potentially dirty contancts, etc, it fell apart, with little ball bearings and spring flying ALL OVER the place :-) So now I am switchless.
So you have the newer switch? Did you have to do anything to make it work? Does the trim fit? Thanks. |

I have the 1983 300SD and my switches are soldered in and
not a connector. Rotten luck. A later switch will be a connector, if you get it that way ask for them to cut some of the harness and then you can splice them together. I ended up pulling internal parts from a good switch and rebuilding mine. The little plastic arms broke and the knobs came off ours. To use memory function (which you say doesn't matter) you would need the seat motor assembly from the car with memory seats. To simply use the switches and not have memory functions should be okay. You will have to map out the wires, which I think has been done here before.

Take a look at this, it may help in the future. Range Rover and MB used the same switch http://www.rangerovers.net/repairdetails/seatcontrols.htm One of my doors had the soldered in switch and I bought a base kit that was easy to install so now both doors have plug in switches. I bought the kit from this place http://**************.com/
