Hi, the AC of my ML350 suddenly has stopped blowing, air despite the control lights working (see picture).
Relevant error codes seem to be B112F-87 and U0164-87.
I believe that I checked all the standard fuses, but happy to retest if you can point to specific ones.
Can someone help with troubleshooting steps? I can't find anything specific to my symptom for this car model W166.
B112F-87 is for the blower regulator has a malfunction.
The first step will be to look at the blower under the dashboard, and check the wiring is properly connected. Check the power and grounds at the connector to verify that the AC control is commanding the blower.
