So I've replaced all the bulbs behind the buttons in my HVAC control unit with LEDs but have noticed that the amber light above the RR A/C Manual button no longer illuminates. The button works because the rear heat control works. I realise the bulb is soldered onto the circuit board but I'm not able to find what bulb I need to replace the burnt out one with. This is for a 2005 Pilot EXL in Canada. Any help appreciated!
