My 1995 405 glx 1.9td (with aircon) has a fault whereby once the car is started both radiator fans are running.
I have spent much time trying to trace the fault and have checked the three fan relays which are OK.
The fans continue to run with the radiator temperature sensor unplugged (as well as both sensors in the thermostat housing). I have tried to trace all the wires connected to the three relays, little success due to peugeots numbers on the wires being difficult to find.
There is a relay coil control wire, on the nearside relay which is live and so activating the relay, I ca't find where this wire goes? The wiring diagrams in the haynes manual do not cover the control from the Bitron Aircon control unit.
Any help with this matter would be much appreciated. A full wiring diagram would be very useful.
