Recommended Posts

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.

Hi Ibbey,

I’ve never seen this error before but doing a quick search on the internet suggests the error codes you have could be caused by an electrical issue with perhaps the wiring or bad connections, I can therefore only suggest you either look up the details and follow the suggestions to fix them or take the car to an auto electrician asking them to track down the fault.

hope hope that helps….
