A/C compressor doesn't work

My old a/c compressor didn't work, clutch wouldn't engage and air wouldn't blow out of the vents, so I replaced the a/c compressor yesterday.

Air now blows out of my vents, however the clutch doesn't engage.

I have no idea where to begin diagnosing the issue.

Any help is greatly appreciated.

Found the solution, the fuse for slot #37 was missing. Replaced it and now the clutch works perfectly fine
