It is on the bottom side or it is the line holes on the front.
The engine temperature sensor is located next to where the upper radiator hose attaches to the engine. The computer uses that sensor to decide when to actuate the radiator fan relays and turn the fans on.The engine temperature sensor is located next to where the upper radiator hose attaches to the engine.

The engine computer uses the signal from the coolant temperature sensor to decide when to activate the radiator fan relay.
In a Vauxhall Signum, the sensor that activates the radiator fan is typically located on the engine's coolant temperature sensor or in the radiator itself. This sensor monitors the coolant temperature and signals the fan to turn on when the temperature exceeds a certain threshold. Ensure to check the vehicle's service manual for the exact location, as it can vary based on the engine type and model year.
Try replacing the radiator fuse relay
There is a sensor that detects temperature to turn the fan on in some vehicles, this sensor may need to be replaced.
It is the coolant temp sensor near the upper radiator hose.
that would be either fan switch or temperature sensor

there's no switch, it has a temperature sensor.
Test the relay and the temperature sensor.
This could be due to a bad temperature sensor, radiator cooling fan relay, or possibly even the radiator fan itself. Try tapping on the radiator fan to see if it starts to move while the vehicle is at normal operating temperature. If nothing then find temp sensor and unplug and jumper the electric connection with a paper clip to see if fan starts. If fan starts then replace the temp sensor. If fan does not start then suspect either bad fuse or bad relay.
