FIXED!

Through some more digging into the wiring diagram I found that all affected functions, including several things I didn't mention that were setting codes in the AAC module through SDS-DAS, ran on the Z3/1 splice, which gets power from relay K30 in the main fuse box. I opened it up and founf that the relay had come fully unplugged and was lying on its side, it's a wonder anything had worked at all at any point during this project. All functions are now normal.
