Engine is overheating because the cooling fan is not working

I know for a fact that the fuse, relays and the fan motor are good. When I turn on the air conditioner the drivers side fan comes on but the passenger side fan doesn't come on at any time.
When I hot wired the passengers side fan and it will work.
It must be some kind of sensor or similar part that's stopping the fan motor from working.
I need a wiring diagram of the electrical circuit of the fan motors for the passenger side and drivers side circuits.

Car is LTZ model
