Dead battery and dead horn

I went to start the Boxster and it had a dead battery. It had been sitting for about 2 weeks (maybe 3). I put on the charger and the battery took the charge and starts.

Today I decided to tackle the dead horn (went to the Renntech to see how). I checked the fuse, its OK. I played with the air bag and I hear a click click as I push/pull the air bag. If I pushed in the airbag.. click, then pull out the airbag.. click. This tells me that the bushing/springs are bad in the steering wheel. But the horn never sounds.

So I conclude that the air bag may have been stuck in, causing the horn relay to stay shut. This could be enough of a draw to run the battery down in a couple of weeks. I pulled the fuse and played with the air bag, no clicks.

So I think I elminated a battery draw, but I still have a dead horn. I'll disconnect the battery charger and check again in a couple of weeks. Next I need to find the horn, test it and get a T30 screw driver to remove the airbag.
