In a 97-03, the bulbs are soldered into the circuit board of the heater controls. Remove the heater control assembly and disassemble it to the board. Desolder the bulbs and replace with new ones from either radio shack or corvetteradios.com. The bulbs are 12v but I don't know the wattage. CorvetteRadios has bulbs for the CD player as well which are similarly soldered into the circuit board on the face plate.
pull the front facia off the heater dials then you find a white box which is to operate the heater dials remove the front from there which is clipped on then there are your bulbs

The bulbs are actually soldered into the circuit board. The only way to change them is to dismantle the whole cluster and desolder then re-solder the bulbs.
To change the light bulb for the heater control on the 2006 Tahoe, you will either need to replace the entire climate control panel or remove and re-solder the bulbs. You can remove the bulbs by first removing the dashboard bezel and then the dash itself. Access the bulbs and pull them out of the control panel. Solder new bulbs into the panel.?æ
there is two rods that go through the housing from the top. turn them to unlock and pull up and out then the whole assembly comes out and you can change the bulbs.
Take your car to the dealer or body shop.
I had this problem about a year ago. Turned out to be all the bulbs were burnt out on mine. There's 3 (or 4) miniture bulbs that are accessed by removing the heater control.
