OK, let me back track a bit and explain. This summer my sunroof wouldnt open all the way, i would have to keep tapping the switch to inch it open, finally I had enough. I wanted to check the connection so i pulled down where the switch was and disconnected the switch and plugged it back in. then the sunroof worked, so i tried it each way and held it each way for a few seconds, its been fine since.

So I figured I would do the same thing when the seat got knocked out of Synch. So i pulled the three plugs out of the front of the seat and tried it over and over again, the stupid thing just would reset itself. But then i looked underneat in the back of the seat!!! There was 4 plugs there which i later determined to be the power plugs to the motors. I disconnected them and plugged them back in. What I think happens is when you unplug the motors, they forget where they are and need to be resynched. So i plugged them back in and did the full extent movements of the seat, holding the button a few seconds at each point. After the seat learned where it was, it remembered, and now the seat works great. Before I had unplugged the seat motors, they were remembering where they were at the wrong points, and there is no way to reset these points unless you disconnect the power to them. So Case Closed!!! Thanks for the input Gilly!
