Hello everyone,

I have a Lexus RX450h, coming up with Climate control system erra contract your dealer.

none of the buttons for heating, fan, ac, rear screen , door mirror heater not working.
All radio/ sat nav work perfectly everything in car works no issue.

I have tried a diagnostic to see any codes stored, it is showing code:


I already tried another HVACCM and tried another Radio to see if the heater button have any issue but nothing made any difference.
I wondered if anyone had this issue, please anyone can help.
