Check these fuses that are shown in the pic. This can be a module that has gone bad as well as the control. You'll need to see if the blower motor in rear is getting power which is what's wrong, there may be a relay near it so check that. That may be in the right fuse block on ip. If your a/c works ok in front then you are getting it in reare only the air is not being blown around is the problem.

Shoot forgot about battery drain. Unplug your abs unit anssee if that stops the battery drain. If it does it needs to either be replaced or rebuilt. There is a transistor that goes bad and causes that. Your brakes will still work, just no abs.
