: Passenger seat motor

08-12-10, 08:24 AM
I have a 76 coupe de ville, the passenger seat will not move back. The motor spins, I can see it, but I cant see any gears worn out. Will I have to remove the seat? Any tips would be appreciated, thanks.

The easiest thing to do is disconnect the electrical connections and then unbolt the seat riser from the floor pan and remove the entire seat. It would be next to impossible to unbolt the seat frame from the riser, there just isn't any room, especially on the transmission tunnel side. Just be sure to mark all your electrical connections, bolts, nuts, washers, etc. carefully and clearly so that everything goes back to where it came from using masking tape and a sharpie. Ex: unplug a connector and mark both ends "one", the next "two" and so on. Same with all hardware ("left track front bolt"). And then put everything loose in sealed baggies so as not to lose anything. Remove the seat from the riser. Put the riser on your workbench, hook it up to a twelve volt power source and see if you can spot where the problem lies. Once you have corrected the problem put the riser back in the car (without the seat) reconnect it and make sure all the functions work as they should (back and forth, up/down, tilt). Re-remove the riser, attach it to the seat and reinstall the entire seat assembly.

While you have the entire thing out make sure to inspect and clean everything. Make sure the electrical connections are clean and shiney, the wires have no nicks or abraisons and the insulation isn't cracked or brittle. Insure everything is properly lubricated, not over lubricated (which attracks dust and dirt) and make sure the motors are in good shape (windings, commuters, shafts, etc.) so that you do not need to redo this for another 34 years.
