Well, let's continue on.
You said fuse 11 controls A/C memory. And it's been holding.
Any ideas on the radio (Sirius) station memory settings?
Sirius says it's Dodge.
Dodge says it's Sirius.
I changed out the radio and it still happens.
Oh yeah. Remember? I threw all my tools away!

 

Looks like fuse M12 in TIPM is constant power feed for the Radio. It's 30 amp fuse though, which strikes me as serious overkill if it's just a memory thing......
