Auxiliary Fan (Compression Shroud) DIY [Air Conditioning]

[corNIC]

I just replaced the fan it's brand new and it even worked a few times right after I replaced it! I don't understand. The only thing that could have gone wrong is a noticed right after I replaced the fan that it got stuck on the fan cover and so it was 'on' but not able to spin but I noticed this problem within a minute or two so I highly doubt the fan itself is fried especially after it worked once after I fixed that. This is totally driving me insane as from what I have read everywhere there is nothing whatsoever to control the fan in between the wiring and itself. There is however a 3rd wire on the power connecter that was messed up on mine but I fixed that also. I just need to know what other component if any could cause this. My wife is about to kill me.
