Hope you can help. My fan stopped working after the car was unused for a couple of weeks. I tried the reset procedure and it came up with the fault code Eb and the service message both flashing on/off. I replaced the fan (it was seized) and a new transistor control and it then worked. Unfortunately the heating was on all the time but the fan worked ok, all the controls appeared to work. The fault codes were still on so I tried the reset procedure again. This time the service didn't show and the fault code was then just b - steady display. None of the functions of the display now work all that is shown is the bare icons. No temperature, fan icon only but no control??Any ideas?
