jimmyk Posted October 25, 2015 Report Share Posted October 25, 2015 What is the HVAC backlighting bulb number? Three bulbs light the square buttons. dhh3 1 Quote Link to comment Share on other sites More sharing options...
dhh3 Posted October 26, 2015 Report Share Posted October 26, 2015 I'm not sure what you mean by the square buttons, but if the 3 big round ones are like the Nitro they are small bulbs soldered onto the circuit board. Quote Link to comment Share on other sites More sharing options...
jkeaton Posted October 26, 2015 Report Share Posted October 26, 2015 Check superbrightLED's, they have a bulb chart for cross referencing dhh3 1 Quote Link to comment Share on other sites More sharing options...
jimmyk Posted October 26, 2015 Author Report Share Posted October 26, 2015 Square "mode" buttons that change the airflow from dash, floor, defrost, A/C, recirc, etc have tiny bulbs that back light the buttons. The three large round knobs that operate the fan speed and temperature are lit by square LEDs. I need the tiny bulbs that light the square puttons. I will check the dealer. Hopefully wont get the answer that I have to replace the entire control unit. dhh3 1 Quote Link to comment Share on other sites More sharing options...
dhh3 Posted October 26, 2015 Report Share Posted October 26, 2015 OK. Now I see. You have the old style dash. I have no square buttons! Quote Link to comment Share on other sites More sharing options...
