    1988 Power seat repair help requested

    I am the new owner of a 1988 Pearl White Allante. Its in great original shape, body/paint is near perfect as is the leather interior. However I have a couple bugs to work out.

    I can't get the driver's seat to move forward (its all the way back). This was a problem before I bought the car as the lower seat cover panel that houses the seat switches was already removed.

    I have the seat switches out to clean, but that's not the problem. I can jump the wires to move all the motors except the one that moves the seat forward. The motor for the forward-back motion appears to use the Lt Blue/Blk and Violet/Blk pair of wires. The wires have what looks like motor resistance between them. It sounds like it wants to run, but it just doesn't move. Can't tell yet if its jammed or a weak motor.

    I would appreciate help on how to get to the motor to test or remove it. Note the seat is all the way back, so I can't see how to remove the seat itself. Instructions for that would also be appreciated.

    It would also be helpful if there was a manual way to move that seat forward. Anyone know how?

    Thanks, Bill

    Can you raise the seat and get to the bolts holding the seat to the track rather than the track to the floor?

    Thanks, thats a good thought, but there doesn't seem to be enough clearance at the back. Additional ideas are greatly appreciated!

    The cables that go from the underseat motors to the seat track are much like speedometer cables. Years ago I got a long cable from a wreck and attached it to the seat track and to an electric drill. With a variable speed drill I was able to move the seat.

    Your allante has separate motors - switch the defective motor or swith
    to the one you don't need to use

    Sorry, haven't gotten back to working on this for a while.

    Carnut... Is the forward/back motor the center one of the 3 motors under the seat? That one has a cable that goes to each track. I may be able to remove those cables at the seat track. Believe it or not, the Factory Service Manual does not show which of the 3 motors is for which function.

    MachDemon... Its a classic Catch-22. I can't remove the seat to get to the motors unless I can move the seat forward to get to the seat mounting bolts in back.

    Yes, the motor with the cables going to each track is the forward/backward motor. It's usually easier to disconnect the cables at the motor.

    Thanks, I'll see if I can disconnect at the motor.

    I had the same problem. I bent back the sheet metal 'keepers' from each of the two speedo cables, and removed the cables from the two worms. I then used two square sockets (1/8"?) and a 1/4" ratchet and extentions to drive the worms and slowly move the seat forward enough to get a socket on the seat track bolts in the rear.
    BTW, the right-side worm turns CCW, while the left-side turns CW (or is it the other way?
