Question about 1991 Peugeot 405
Hi I have a 90/91 405 gld saloon. The twin cooling fans have stoppped working. There are THREE relays for the fans. What does the Third relay do? and any suggestions as to how to get them working again?. I have powered the motors and they are fine. there seems to be no power to the plug on the switch that is built into the Radiator. Thanks John I have the same problem with a '93 405 except I cannot even locate the relevant relays and the Haynes manual is deliberately vague on all locations and wiring specs. The wiring supply from the radiator thermostat switch has 3 contacts and shorting any or all combinations produces nothing.
Hmm, perhaps it is time for a noisy solution.
Get a 30 amp relay and wire the fans via directly to the battery via that relay. Of course, disconnecting them from where that are wired into the vehicle now.
For the fan control to the relay, wire something that is (+) when the ignition is in the 'run' position.
This, of course, is the quick n dirty fix. While this will work, you have an always on, noisy solution, and it will take quite some time for your vehicle to warm up in the winter time.
Just an idea should you not be able to correct the factory wiring, of which I have no idea.
Best of luck,
