Hi,
It may have been happening for a while but I noticed that my 'air con blower' was continuing to run after I switch off the system (Pressing the fan button) or even when taking the key out of the ignition? The only way I can stop it is to pull the fuse behind the glovebox.
If I replace the fuse the following day the system 'behaves itself' for a day, sometimes two and then the fan runs on again. Back to pulling the fuse.

I have replaced the resistor pack at the bottom of the blower motor behind the glovebox, no difference. I have searched the internet for the location of a blower 'relay', there is loads of diagrams and they are the same as my owners manual that show 'relay 7' as a possibility in the engine bay fuse board but it isn't there (no connections to plug one in) in my version.

I am lost as to what to do next, has anyone had this / sorted it please?
Many thanks.
