Replaced auxiliary battery - now now climate control...
Gang... I think I had this issue about a decade ago on my E55... or maybe it was this E63... can't remember...
But I had to replace both of my batteries (car only gets driven about once a month now and still only has 55k on the clock)... after replacing the primary, everything was fine. After that, my aux died and replaced that (both with MB batteries mind you).... and now my climate control panel works but no air moves (no blower fan). I think on my E55 I actually had to get that replaced at one point.
I pulled my f12 fuse and let it sit for a bit to see if that reset anything. No dice. When I get a chance later I'll disconnect the primary and let it sit for a while to see if an ecu reset will do anything.
Just wondering if anyone else has encountered this. I couldn't find any relevant info other than a post from 2016 on an E350 (thats where I got the idea for the f12 fuse).
Sadly, I think after I resolve this I'm going to sell the beast because it just sits nowadays.
