No adaptation is required. I strongly suggest you look again at the B82 component fault. ie double click on the fault code in DAS and go from there.

Do you have "star finder" software on your DAS system?

All fuses have been checked. Nothing can condenser as faulty cable or fuses. Rear blower working as normal and give ok value.

Front blower cannot control and the blower motor working and stop working itself. Speed control cannot change, AC compressors is not engage. B82 interior humidity sensor is not possible to find.

Anyone can help!
