Hello, I own a citroen c5 2004 model. All about my car were ok but today when I turned off engine and switched off light....lights on air condition panel doesnt turned off!!! I tried to start again engine...lights...lock-unlock car but still ai condition panel its on!!! What possibly happend...and what I can do to shut it down...because I am on a trip and I cannot visit my service. Thank you in advance
