Radiator fan not working - 1994 Dodge Caravan

How does a car radiator fan work?
The engine cooling fan is designed to move air through the radiator when the vehicleis at slower speeds or stopped. This air flow removes heat from the coolant created by the engine using the radiator as a conductor. An engine cooling fan is temperature controlled to only run when needed.26 Jan 2017

This details will help.

Thanks.

that has 2 sensors one ac and one cooling should b a sensor on shroud near cooling fan

The fans cool the radiator and the condenser. one fan is the radiator fan and the other is the a/c fan. The can and do operate independently of each other. The radiator fan will work anytime the engine is hot enough for the temp sensor to command it on. The a/c fan will come on when the a/c is on and the high pressure switch commands it on.

If the a/c is not working than it is possible for the radiator fan to work and the other fan not to work.

I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

Which fan is not working, A/C or Radiator? Check fuses, if good disconnect fan plug, direct wires from battery to fan to check fan, if fan does not work change. If fan works check water temp sensor for radiator. A/C fan only comes on when A/C is switch on. Like wise radiator fan only comes on when water reaches a certain temperature.
