Hi I have a scenic with climate control and the fan has started to work intermittantly. I have followed these excellent posts and removed the surround panels but my wiring appears different- there is a unit at the top with two green plugs which i suspect feed the control module but i am unsure- if this is the heater contol unit then is it easily replaced or fixed?
I too have just found the electronic version of the fan control you describe.
I also happened upon this site where you can have either control repaired.
It seems the dash clocks may need to be pulled forward for better access.
I hope this info is helpful guys.
