Hello! I have a 2006 LR3 HSE. I recently replaced the face and footwell heater blend stepper motor and now nothing works on the HVAC control panel except for fan speed. My iCarsoft tool shows a fault code B1A98-15 "Local interconnection network bus circuit 1" . Seems like something is disconnected somewhere. I checked relevant fuses which are good. Any tips on how to fix this?
