Heater Fan Not Working On C5 2007 Model

[MichaelDavis]

As per title my fan wasn't working - plugged in my mechanics Snap on code reader and found heater relay stuck open - reset code and heater fan now working. My question is where is the heater relay so I can replace it - all I can find on the internet is reference to heater resistor on earlier model C5?

just look  down at your clutch pedal. you see the piece of plastic trim to the left of the clutch pedal  well its behind that. chances are it will be 2 green muiti plugs with thick and thin wires attached to them

Great thanks I will find that.

I haven't done anything with heater resistor - but I have fitted a brand new slightly more amperage battery and heater has been fine. I had a computer hooked up to my car recently and no faults were found which is the first time in 3 years I have ever had no codes!!! So maybe anyone having faults show up should try a new slightly more powerful battery - my old battery was tested and I was told it was fine but clearly it wasn't.
