The Problem
My car engine has been over heating. I found that one of my fuses was missing completely so i replaced it and the fan worked!
Unfortunately the problem has returned less than a month later and when i checked the fuse it was fine.
The only thing i can think is that it was pot luck that the fan started working again.
I've trawled the internet for hours and people keep talking about a 'radiator fan switch'.
I have no idea what this looks like and would appreciate someone telling me where it is :)
This is my last hope before I have to pay a garage to inspect it!!!!

Might be wrong but I think the temperature sensor is on the end of the engine block. Looking from the front of the car on the right hand side - below the head.Either a 19mm or 21mm spanner to remove . If not , on some cars it's on thermostat housing .

This seems to confirm location of switch,
" Peugeot 307 cooling fan problem.
The fan is activated by a thermo switch screwed into the cylinder block’s water jacket. "
Simple and cheap 2 min job to replace switch .Just remember to change when engine cold or you might get scalded with water .Disconnect wiring / plug , unscrew and fit new switch .
Hope this helps you .

you may have a fault with your fan resistor.does the fan come on when you switch the airconditioning on?
