Hi Folks,
First post here. Tried searching the forum but didn't come up with a solution. I have a 2007 C2S coupe and after boosting a completely dead battery the drivers door now has no power (including light, window switches, mirror control and memory seats) but does lock and unlock with the key fob. Window is in the fully down position. I checked the obvious fuses A1/2/3/4 and all are good. Am I to assume the door control module behind the door card is blown or is there anything else I can check before removal? I live a 10 hour drive and a 6 hour ferry ride from the nearest Porsche dealer so DIY it is.

Thanks in advance for any help you can offer.

Fully charge the battery then disconnect it for 10 minutes to reset all the modules and see if the functionality returns.

I forgot to mention that I tried this without success. After disconnecting and fully charging the battery for 24 hours, no change.

Ahhhh…..yeah. I guess so. Hope you get it figured out. That is a peculiar fault.

might want to check wires in door hinge

Finally getting back to the 911. Door hinge wires checked out fine and I used another code reader and nothing comes up. Someone mentioned there is a second panel with fuses in the passenger side footwell. Anyone know if this is true and if this could be the source of the problem before I start taking it apart?

Also, car is not showing any codes.

Thanks in advance for your replies,
Corey

No faults doesn't make any sense if the door control module isn't communicating at all or dead, especially with every other module looking for it. And did you happen to loosen the ground or secondary ground (smaller wire) attached to the battery? That smaller connection at the battery terminal is literally for the door control modules only.
