2009 mb s550 ac/ heat blower not working at full power

I have a 2009 s550 when i turn on the heat or ac it blows heat but not fully, i put the blower on highest level 7, and it does not blow very much, in the rear it blows less, like almost nothing, sometimes i have full speed in the front but in the rear there's not much. can someone help me with this problem any help would be appreciated thanks I have an iCarsoft mercedes diagnostic and it gave me the code 951D A32n1 (Blower regulator) : LIN bus communication error, but i'm not sure about the accuracy on the
iCarsoft diagnostic.

I had a white 2009 before trading for my 2013, and it had the exact same problem. I had the blower motor replaced twice before I lost the car in a flood in New Orleans back in August. No issues with the 2013 so far. It sounds like a common problem.
