Diagnosing climate control fan staying on while vehicle is off, and no AC

Hi, got this e46 with no AC issue.

Lines have Freon in them, compressor clutch engages, but no cold air. The air control on the top two vents are also turned to cold ..

Took the car to get detailed , then the fan just stayed on the entire time. Turned car off, waited for 16+ mins. Still on, had to remove blower fuse to keep it from draining or causing other problems.

Replaced the HVAC unit thinking it was water intrusion, same issue, slightly colder air, but not AC air, couldn’t tell since it was a cold night would have to check on a hot day

Would the fan staying on be the Final stage resistor , and the no AC being the Water (coolant) control valve? Or is there anything else I can check
