Liber_A4_te Posted November 21, 2016 Share Posted November 21, 2016 Can some one help me solve my mystery? Purchased a 2008 Audio A and after 3 months my air con is blowing red hot on the passenger side only. What would cause this? Quote Link to comment Share on other sites More sharing options...
Trevor Posted November 22, 2016 Share Posted November 22, 2016 Hi Phil....welcome to the Forum It sounds like it could be a diverter valve on the passenger side not switching over to cold. Maybe try switching it over and back several times to see if the valve starts to move, if not then not sure if there is any way to check it without physically inspecting it. You may be able to control it through a diagnostic platform if it is within the programme settings. Let us know what you find with it Cheers Trevor Quote Link to comment Share on other sites More sharing options...
