Electric fan wont run properly

[1QWIK6]

I noticed my car running hot. I found the fan is not turning on. If I hot wire the fan it works, but otherwise it won't turn on.

What is a common failure for this condition and how do I fix it?

are you bypassing the relays when you say hot wire the fans??

Yes

does the fan come on when you turn the a/c on ?

Did you check for volatge on your original wire to the fan before you hot wired it?
