Hi Guys,
I have the same issue, nothing happens when I turn the heater knobs. The heater display on the screen is greyed out and doesn't change. The rear windscreen button lights up...
Just tried the reset, nothing happened...the buttons did not flash
Catman, how do I get to the connector under the glovebox? The heater was working...I just checked the photos in the original advert and I can see all the lights and icons on the screen lit up...the previous owner also confirmed that he never had a issue. Im hoping its a dodgy connection. Failing that there is a company in Leicester that repairs them for £90.
