So I own a 2013 Cadillac CTS 4 3.0L and recently my radiator fan stopped working on idle? Why? Any ideas?

So basically as I drive it turns on however if it's parked or on a stop light for a while it turns off resulting in hot air while ac is on you can hear the click that usually turns it on but still nothing.

    "Hot air while the AC is on" has NOTHING to do with the radiator cooling fan. The electric fan that draws air through your car's radiator is controlled by a thermostatic switch. The radiator fan should ONLY come on when the engine coolant is above a certain temperature. It should NOT run when you are driving at normal speeds.

    If it's NOT working that way, take the car in and have the system checked by a REAL mechanic.

    After working on cars for 40+ years, it's my considered opinion that something is wrong with it and needs to be fixed.

    Why do you have a radiator in your car? It’s all about fireplaces in 2019
