NO AC Please help

Ok I have searched and did everything I could find on these threads I have no air coming out the A/C and now my battery keeps draining . I have changed the FSU I also have changed the blower motor along with checking all fuses to make sure all are working. Just two days ago I changed the climate conrtrol module to the newer 2004/05 one. I don't know what else to do.

To clarify. Is your AC not blowing cold? Or is the blower not operating?

In regard to your battery going dead, was it doing this after you had swapped out the IHKA? (module)

Sorry took on the project over the last two days didn't think I would receive a response it had to do with the relay as soon as i replaced it kicked it however upon looking at the wires connected to the relay I noticed they were a bit melted but now everything is back and running after three months of no AC
