    Power Seat Motor Running But No Movement

    So my driver side seat motors all work in terms of running when power is applied from the switches. The front of the seat base tips up and down, the entire seat slides front to back, and the back reclines. However, the seat won't lift up or down. I hear the motor working but nothing changes in the seat position. Is the cable broken or is it gear driven? I haven't removed the seat yet but I'm curious if others have had the same issue. Looking through the parts diagrams it appears some of the cable guides are NLA which is not good. Any thoughts are appreciated...

    Don't keep messing with it! You will break the gears on the fore/aft movement. You have suffered a sheath shrinkage problem which pulls the cable out of the gearbox.

    He can get you squared away.

    Sent him an email. Nothing yet. Does he still work on seats? When was the last time you heard from him?

    PS: Received a very nice e-mail from Paul Brill today (1/29), giving me info on his product that will cure the lack of vertical movement in the seats. THANKS PAUL, and thanks also to Masbury for the suggestion.

    Did you ever find a solution to your up/down seat issue? I have the same problem.
