Hi my AC button and Rear defroster button stopped working and do not light up anymore. The fan works good, and all the fuses looked fine. Thanks for the help.
Thanks

Okay, this may be somewhat involved. Either a ground was lost or the headlight switch itself is bad. I doubt that both burned out at the same time. What you need to do is start by checking for power at each light socket. If there is power, then you have a ground issue or both bulbs are bad. If there is no power, then the headache starts. You need to trace the power supply back to see where power is lost. It can be a nightmare.
