Can any of you electrical gurus take a crack at this question please? - 986 Forum - The Community for Porsche Boxster & Cayman Owners

I worked on the driver seat of my 986.2 (2004 Boxster) last week and learned a little about the connections and motor controls. The picture you show does not look like a motor control plug. The motor control plugs on my car can be accessed from the front of the seat and you can even unscrew the 2 torx screws holding the control module to the seat (see red arrow at top left). The power input is indicated by the central lower arrow, and the three motors are powered by the three connectors circled to the right. I assume you could unplug these motor cables and supply power directly to the motors by connecting + to either red or black (forward and reverse) and - to the neutral (white).

I think you will have better luck if you remove the control panel on the side of the seat and apply power at the rocker switch that controls the function there. The seat plug simply supplies power to the various switches, but the rocker switches complete the circuit and direct voltage and polarity to the motors.

Thanks to so many of you and others for offering generous advice and wisdom. I got the seat out! I'll start another thread about how so that those with this problem in the future will find it easier to find on a search. This work was on 987.1, not a 986, so I hope all of you and the forum moderators won't mind me posting it here on the 986forum. I figure there's enough similarities in the 986 and 987 that it'll be helpful to all. Thanks again everyone, what a relief.

By the way, the rear body control module, which sits in the same well as the immobilizer in a 986, is shot. However the seat memory module which is strapped the the underside of the drivers seat cushion, is untouched. That's great news in that is tells me that I do not have to replace the module as it's pristine and untouched. More importantly it tells me that the water in the car was even lower than I thought, it did't even reach the underside of the seats. Great news. :dance:
