Heat is not coming from the lower vent
Hi guys,
I've a strange issue on my C63s and wondering if you have had such XP and what can be the possible solution.
When I distribute air to the lower vents from the control panel, air is not coming from them, but the central ones. What's more confusing is that central vents should not blow whatsoever in heat mode as I know.
I've tried to find a solution, but couldn't even find such issues. I guess it should be controlled by computer and there might be an issue with fuses?

UPDATE: Fixed, if someone have the same issue.
A1699060100 part is the HVAC Floor Mode Door Actuator, needed to be replaced.
EDIT: Also, if anyone decides to change HVAC module, it needs to be reset/adapted/programmed, otherwise it won't do normalisation and actuators won't work (HVAC module - A2059009230)
