Fault Detection: RADIATOR Electric Fan Circuit

We can detect faults in the radiator fan circuit quickly and easily.
First we must locate where the two relays that control the RADIATOR ELECTRIC FAN of the car are.
To do this, we look for the following phrases on the cover of the engine relay and fuse box: COOLING FAN HIGH, which corresponds to the high-speed relay of the radiator electric fan, COOLING FAN LOW, which corresponds to the low-speed relay of the engine radiator electric fan. .
In case the electric fan does not activate, we can loosen and remove the high-speed relay from the electric fan and with the help of a cable we make a jumper in the relay socket on the power terminals that correspond to the largest terminals.
If the fan is activated when this jumper is made then there may be damage to the relay.
The previous procedure must be repeated with the low speed relay of the electric fan.
DO NOT MISTAKE THE TERMINALS BECAUSE IF WE MAKE A SHORT IN THE TERMINALS THAT CORRESPOND TO THE COIL WE CAN DAMAGE THAT OUTPUT OF THE CAR COMPUTER.
