nite 0 Report post Posted June 10, 2022 Hi all, as of this week my Aircon Button doesn't appear to be working. All other buttons light up and change the climate control as expected but the "Snow Flake" button doesn't light up or change anything on the display. Checked all the fuses and everything looks good. Has anyone run into this issue before? Is it possible that the button is broken and I need to replace the unit? Quote Share this post Link to post Share on other sites

NZ00Z3 189 Report post Posted June 10, 2022 (edited) Have a read of the attached file. Does the electric radiator fan run for 20 seconds when you turn the engine on? That is the DME doing a fan check. If it does not run, then the power controller on the fan has failed. New fan needed. The DME will register the fan failure and not engage the AC compressor clutch. INPA is a goot scanner to check for IHKA problems: https://www.e46fanatics.com/threads/how-to-install-bmw-standard-tools.1274003/ 8 Climate Control.pdf Edited June 10, 2022 by NZ00Z3 Quote Share this post Link to post Share on other sites
