Climate control issues front and back.
 
Hello so before i start my battery is good and close to new so its not the issue when you have low battery discharge it defaults to the defrost upper vents for safety.

Front issue:
I've tried everything and can't find anything or figure it out. When i hook it up to my Reihngold INPA scanner i scan see the flap positions but when i trigger them i don't hear anything. The fan blows no problem but i can't get it to change to the middle or lower vents. I've tried messing with the iDrive also.

3rd Row issue. The green light doesn't come on and the supply power fuse 93 at the rear is fine. I'm not sure if the unit is acting up and screwing up the bus line to the main HVAC (IHKA) unit.

i'm not sure if they both stopped at the same time as i don't use the 3rd row all the time.

Help please before it gets really hot!

Fyi, pulled the battery and let the car sit, (could have reset the IHKA also) and all is working again!
