I have a 2000 Max, the climate control lights have gone out. Does anyone know how I can replace them?

 

If it is like the 2002, and i think it is, the light mounts from the rear of the controls. It is kinda a bear to get the air vents out that are located above the radio, but the rest is pretty easy.
If you need details on getting the vents out try pro-fit-intl.com and look up your maxima pro fit install instructions for the removal.

 

Do you know where the bulbs can be purchased?

 

Sure dont, other than nissan. Never looked though. Auto parts stores might have em.
