my 1998 peugeot 406 radiator fan comes on even when the car is not that hot and even after l turn the ignition off it comes on and staya on for a bit, flattening my battery! Is it a dodgy sensor? Would cut the wires to it but then will overheat soguess could fit a manual switch, do you think its a sensor, cheers, thanks

It sounds like the sensor is abit dodgy not to worry very cheap to fix do not put a manual switch in because if you forget to swicth in on one day BANG and it cost you alot more this part is very cheap go to your local scrap yard should cost about a fiver.

Hope this helps.
