Driver seat controls

[CDNIcecube]

Hi again,

1999 Boxster base. 5-speed.

Question, the driver's seat back electrical lever works but the vertical lever does nothing. No electrical engine sound or anything. This is new to me Boxster so I have no idea if this is normal or not. Are all seat adjustments, except forward /backward, electrically adjustable? If so, Is this a common problem and easy fix?

Thanks!

Ps. The passenger seat does not have this lever at all, just a plastic cap. So I can't compare the seats controls.
