peugeot 306 cooling fan wiring diagram The following article discuss the 1996 Peugeot 306 Cooling Fan Circuit and Wiring Diagram. Herein you will find also detail explanation of Peugeot 306 Cooling Fan basic principle. The engine cooling fan system is made up of the following parts: 2 fan motors, 3 relays, control unit and the coolant temperature thermistor (NTC). The 2 fan motors always run together and have 2 speeds available. At low speed the motors’ power circuit is switched in series and at high speed the circuit is changed over to parallel. A ballast resistor is therefore not required. The switching of the power circuit is done by the 3 relays which, are controlled by the control unit.

The power circuit starts at the battery, to the engine bay fuse box through fuse 33, to pin 3 at the "left fan relay", out at pin 5 of the relay to the left fan motor, from here to the "change over relay". The change over relay is at rest and provides a path between pin 3 and 4 to the right fan motor, the circuit is complete at pin 2 of the right fan motor when returning to earth.
