the lights on the rear air-heater-wiper switch was on untill I pulled off the pannel to see if I could replace a light bulb on the rear air switch then when I could not find the bulb on the switch I replaced the panne and now none of the lights come on, what gives on this stupid setup.

Hello, you might check the illum fuse in the fuse box, 10 amp fuse. Your talking about the instrument cluster lites? That fuse circuit goes hot with the lite switch.

Hello, I am having a problem with my 2002 Chevy Astro dash lighting. This is the HVAC controls and the rear a/c, heat, and rear wiper control. Also 2 buttons on the radio. all instrumentation lights are on just fine. I am including a pic of my controls and radio just to show my configuration.

Gray wire in the diagram is voltage, black is ground. Check the bulb, where applicable, circuity. The voltage wire can go hot with headlamp switch.

Thanks for your reply. So I am guessing that the Grey wires are made hot with the Headlamp switch and a proper fuse. So if I were to swap the headlamp switch with a known good one, this would rule out a defective Headlamp switch. The picture attached is the switch you are talking about right?
Thanks,

Mike.
