W203 HVAC control panel not going to sleep - current draw

Need help diagnosing battery drain on a '06 C55. I have searched the internet and have come across several posts related to the battery drain issue with different parts mentioned such as seat heaters and overhead console causing the drain. However I seem to have an issue that no one seems to mention... my HVAC control (in front of the gear selector) panel stays on at all times. Nothing else seems to stay on except for the panel. Any ideas?
