Heater/AC and PW control lights

'02 Sub has lost the lights on the fresh/rec and rear def and AC switches and the rear window switches on the driver's door. I can't find the bulbs. Are they replaceable?

did you check fuses...did this occur one by one or all out at one time..

Didn't check them since the front two switches for the front windows and the heater/AC knobs still have the lights working. Figure these lights would be on the same fuse.

again did these lights ALL go out at the same time ?

Dunno, it is the family car and my wife drives it most of the time. I will check the fuses. Should of already done that.

Fuse is good. It appears there is only 1 fuse for all the instrument and control lights

You'll have to pull the control unit out (or remove the door panel) and check the back to be sure, but I believe they use the small T1.5 bulbs with the flat bottom holders...look something like this but with a tiny regular filament bulb instead of the LED:

I'd suggest going ahead and replacing all of them with LEDs, you can even choose the color. Hope this helps!

Window/door lock unit does not appear to have any replaceable bulbs. There are none on the bottom side of the unit. There are some of those barbed hooks to disassemble the unit, but I can't get it apart. Looks like maybe the bottom comes off along with a circuit board. Something is holding it together, it maybe the contacts from the switches above that plug into the board?

I remember a 1995 Sierra I traded last August (Cash for Clunkers, ya know) had the type of bulbs described above on the headlight switch.
