The rediator fan is not automatically switching on when the car heats up or when driving so it causes the engine to overheat.I`ve reasontly replaced the fan switch with a new fanswitch but its still not working.I`ve also changed the relays but still not automatically switching on when the car heats up. What could I do.

There are three relays, one is a fan control relay and low fan relay. Those are the two you should check on. Your control may not be allowing power to go to low relay all are underhood and should be marked.
