Recently had a dead battery in my '06 997S. After a jumpstart and running the engine for a while the battery seems to be charged again. However I discovered my Homelink settings were erased. When I try to reset or reprogram the Homelink I get no response or flash from the Homelink LED light. I'm guessing this must be a fuse issue as I noticed the "orientation light" is also not illuminating. Can someone please inform me which fuse controls this area? All "dome" or map lights work fine. Appreciate any help.

Just discovered both seat heaters are also non-functional now! Power seat adjustments still work.

Ideas?

Pull each fuse until you find one that is blown. There should be some kind of guide in the manual or on the car that will identify each fuse.

Thanks guys. Found the fuse sheet but no luck identifying the affected accessories so I pulled every single fuse for inspection. All were intact!

I unhooked the battery and fully charged it overnight thinking this might reset everything but no such luck. Still no Homelink, heated seats or orientation light.

I'm off to the dealer on Monday.

Go to your dealer 99% chance that a new wake up procedure can help.

I'm sure you already thought of this...Homelink in the 997 is the only instance of Homelink that I know of that has to have the ignition turned on to work.

Nope my Mercedes is the same way - maybe it is a German car thing.

Loren, you were correct!

Just picked up the car from the dealer. The "control unit lost coding" and required a "reprogram and redo vehicle handover". My battery and alternator were all OK.

Everything is back in working order. I've ordered the Chargo-O-Mat II battery chager to help prevent this in the future.

Thanks everyone for your suggestions.
