HVAC Controls vent selection knob light stopped working

[RedLightGreenArrow]

I have a 2004 Toyota Camry with manual climate control knobs. The last knob, the one where you select what vent/how the air is directed, will not light up, however, the defogger button, as well as the rest of the lights, light up fine.

Does anyone know how to go about fixing this? I wonder if it was a loose connection, etc.

try knocking betweet the temp and mode dials; if this doesnt work the bulb needs to be replaced..... a bulb will run u about $5 from the dealer or you can get LEDs like i did

My left and middle lights have been out for about two years now. It's like they have a mind of their own. Usually they don't work but they turned themselves on a couple of weeks ago.
I think it might be a connection problem. I'm just going to go with LEDs soon.
