Here is a thread of people who had the same problem. This may work for some of you but I'm opting to change the bulbs themselves to elimate it from happening again in a while. http://www.elementownersclub.com/forums/showthread.php?t=22376&highlight=change+bulb
via an on board dash reading
You don't replace the lights in the dash board climate control. It is a singular control module. Once the lights in it burn out, that's it. You either replace it for a few hundred bucks or just live with it. A quick and cost effective way to get light in that area is to buy a little 12 volt light that you plug into the cigarette lighter with a flexible neck.
you can't replace the lights they are built in to the control head.you must replace the entire hvac control
The lights for the LCD climate control in a 1986 Nissan 300ZX are typically located behind the display panel. To access them, you'll need to remove the climate control panel from the dashboard. Once disassembled, you can replace the burnt-out bulbs or LEDs that illuminate the display. Always consult a service manual for specific instructions and safety precautions.

Depends on which lights. Pull off the climate control knobs and take out both screws. Give the dash a tug from the sides near the compartments and you can pull the whole thing out.
You can't just replace the lights you would have to replace the whole control cluster.
You need to replace the daytime running lights control module
You can replace the balls in the heater control panel on an XS ARA Picasso by removing the front cover of the heater control panel. The panel lights will then be visible.
if all buttons and lights went out on your climate control then either its not receiving proper power or ground, or the control panel assembly is faulty.
It controls the headlights, dash lights, tail lights and park lights. You don't repair it you replace it.
Check the fuses.
