Well I'm sick of none of the lights working in my HVAC control so I pulled it out today to check them and see if they need replacing. But it looks like all of the lights are still good, but they are small and really hard to tell so I need to use a battery to test them to see if thats the problem.
Is the HVAC set up so if one bulb burns out the rest won't work? Also my rear defrost button doesn't work either. Can I replace just that part or do I have to get a whole new piece?
