I thought it was said on here before that if this happens, you need to open it up and ensure the ribbon cable is properly inserted?
(Similar to the advice with missing segments in the instrument cluster displays i.e. pack the rear of the connector with something to ensure a good connection is made).
I'm having similar problems with the climate control on my 202.
Was planning on opening it up and checking the connections, but do you think it's not repairable?
