Hello people, its been a while since my last visit, any suggestions why the electric cooling fans on my 405 won't switch off, , , , I had to pull the fuse, it all started when the coolant light came on, the coolant level was correct, (with a cold engine), started the engine, coolant light went out after 5 mins,switched off the engine before it was warm, cooling fans came on and stayed on ,, any help appreciated Fitzy
1997 405??? Is that the right car? Or year?
Yes,, ? P. reg 1997 ....405 LX td estate, probably one of the last made, Fitzy
I'd check the switches on the radiator (assuming it is like earlier
405s, IIRC the thermostatic switch for the fans and the coolant level are both on the radiator - there could be a problem with these or a loom fault around there).Matt
Thanks Mat, I will try this area and report the outcome, Fitzy
Try disconnecting the Bitron unit for a few minutes, although when that goes wrong it usually means the fans don't work at all. But you never know! If you disconnect it with the fans running, they should stop. Then reconnect and hopefully they will stay stopped. It's located under the N/S headlight, not easy to get to, and you may need to remove the light unit. Otherwise as Matt said, check the relays, and senders on the fuel filter base.
Cheers mate, will give it a try at weekend, Thanks Fitzy
removed relays from under grille cleaned and refitted, fans all working correctly now, I haven't got a clue what it was, but its working ok now !! Thanks for the help people, Fitzy

This sounds like my problem. Where are the relays? If I stand in front of the car, there are three round connectors (?) on the right (N/S) a few inches behind the headlight. Are these the things?
