The OEM battery in my 3.0si finally died today so I swapped in a new one. Afterwards almost everything works (other than needing to reset date/time), but the climate controls are pretty much non-functional. Fan can be switched on an ultra-low setting, but that's it. No A/C, no rear window defogger. The car runs fine and all the other electrical systems seem to work normally other than this one problem. I checked the obvious fuses and didn't find anything blown.

Is this the "transport mode" I've heard about? More to the point, how do I fix it? I'm many years and miles out of warrantee and would REALLY like to avoid a trip to the dealer.
