AC fan doesn’t blow any air. Had to disconnect the blower plug connected to fan (?) because it kept draining the battery. Is the fuse, module or blower fan bad or what?
What is your question?
AC fan stop blowing and when I leave the the fan motor ( under hood ) connected it drains the battery so I disconnected it. So what could be the problem? Thanks for your response.
What makes this problem better or worse?
No AC and keeping the fan blower connection disconnected so battery won’t be drained.

Sounds like a draw in that circuit that must be resolved. It's impossible to know if it influences AC blower operation -- until you resolve the concern within the circuit that resolves something you know to be failing.
Circuit testing of the wiring and components within the area that is causing the draw should be approached and resolved first. No way to guess - gotta do the testing.
