How do you install a backrest motor?
The car is a '81 300SD
A while back I replaced the seat switch for my passenger seat since the back rest button was busted and the backrest wouldn't move. After replacement, I still have no backrest movement. There is no motor noise, so I assume the motor is shot. I sprayed all contacts with Deoxit. I took a look under the seat and it looks like three motors are encased in a black shell. When I go to the junkyard, what exactly is it that I need to pull? The part # I saw on the shell was 126 820 1042. Thanks

I had a similar problem with my 81 300SD except that the seat would move every way but front to back. I took the seat out, turned it upside down on a table and hooked up my battery charger to the motor. After exercising the motor for a while, it started moving front to back again. Not sure whether it was just rusty or what (had not worked for a few years) but it has now worked for about six months.
Maybe your motor is OK and you just have a rust spot that needs exercising. I thought about replacing the motor if necessary and never got that far. Those motors are awfully good; do not give up on it too soon. |

The backrest motor is up inside the back of the seatback. The three on the bottom are for the forward/back movement of the whole seat, and the up/down movement of the front/rear portions of the seat. The backrest recline motor is within the seatback, the headrest motor is also in there if applicable. You'll need to remove the back cover of the seat.

Thanks for the replies fellas.
pawosd, can I install that motor with the seat still in the car? Any tips on removing the back seat cover without destroying it? thanks

Is it possible to alter these seats, perhaps a set of tapered wedges on both sides, such that front/rear angle is increased so that rotation of the seat is slightly increased?
I reach the end of my travel when my body wants to be more horizontal. (no jokes required ) Thanks. |
