I don't have a VIN so this is best guess based on the car listed on your profile info. S11 is listed at ignition switched power to cluster, S15 is listed as battery constant to cluster.
109 relay is switched (ground control) by the ECM and gets its power from the same circuit that provides battery power to ignition switch. Ironic but fuse for radio comes from same source.
BTW - Double DIN radio has no switched power, just battery and ground. It waits for CAN buss signal from Cluster to turn on.
ECM can command AC off and depending on exact year AC and/or cluster can command AC off. Also depending on exact year cluster or ECM can command fans on for engine cooling. I don't remember if the earlier cars like these do it, but newer cars the fan control module will command fans on if the module looses communication with ECM.

" fuse for radio comes from same source. "
Well my radio isn't powering up so maybe this is the culprit. Not sure if this is a fuse issue though? I probably need to pull open the ignition switch and see what kind of nasty corrosion is in there. I actually ordered a new one figuring it could be related to the relay109 issues. 3 weeks and counting waiting for it from idparts.
I believe my cluster is still good btw. When I got the dashlights working I used a flashlight to stare right into the mileage/clock and I could barely make out some numbers. I think they are just super dim from water damage on the LCD or whatever lights that up. I've seen that happen with other electronic devices. Not sure if that's something I can repair, prob not. I'm probably looking at getting a new cluster and having to go through all that fun immo coding stuff. But at least I know it's probably working.
