" wiring in the door-hinge-tube" Unlikely. Same wires for fore and aft (reversed polarity). But flex cable can work itself out of the socket to the point it only works in one direction.

Since the seat moves backward and not forward, I agree that it is most likely the switch, or in a worse case senario, wiring in the door-hinge-tube. Try contact spray (deoxit) in the switch and operate the switch ~20 times. If that doesn't work, you will either be checking wiring behind the door pannel or under the seat, or both.

The three under the seat are fore-aft, front up-down, and back up-down. You have one of two problems. If the motor runs but the seat doesn't move, the Teleflex cable that connects the motor and the gearbox has "stretched". Bu that, I mean that the end sleeves have walked off the casing making the casing too long for the flex cable inside such that it slips out of the socket at one end. You need to remove the seat to fix that. But, if you are lucky, it's the switch (e.g. motor doesn't actually run on forward). That's easily fixed in most cases by shooting contact cleaner into the switch without disassembling anything except removing the seat-shaped knobs on the switch (just pull). -----Original Message----- From: mercedes-boun...@okiebenz.com [mailto:mercedes-boun...@okiebenz.com] On Behalf Of John P. English Sent: Wednesday, January 25, 2012 5:25 PM To: Mercedes Discussion List Subject: [MBZ] ..Seat problem. The passenger seat on my 1985 300SD will move up, down, backward, but not forward. I am thinking that there is only one electric motor which powers the movements in all four directions. If this is so, then the possible causes of the problem would seem to be 1) a loose wire, 2)a bad switch, or 3) maybe a bad relay. What do you think the most probable cause is? > _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
