Hi, This has happened a number of times over the last couple of weeks on my 2004 307 sw. Today I drove 10 miles and when I stopped I noticed that the cooling fan was going at full speed when I have turned the ignition off. I thought it would stop after a few moments but it only stopped when it had worn the battery completely down! The car wasn't running hot (or cold). I have tried turning the climate control on and off. I also restarted the car and turned it off again but it kept going. I then had to jump start the car and drove 100 miles. When I arrived I switched the ignition off and the fan was not on. Could this be a corroded sensor? Where is the relevant sensor on this car? Should it stop if I unplug it during one of these episodes? Any help would be great. Thanks Lenny
