So my seat height adjustment on the power seats for my 2004 996 C4S just decided to quit working. When I press the button to move the rear of the seat up or down I can hear the motor running but nothing moves. Clearly the button works, and clearly the motor isn’t blown, but any guidance as to what do to to troubleshoot this would be helpful. Thanks!

Haven't had the problem on the Porsche BUT if like most European seats...the square drive cable broke. Sometimes can be shortened and pushed back in.
