SOURCE: 2000 Silverado daytime running lights don't work. bulbs new.

Not saying that you don't know this but the daytime lights are turned off in park.
If that is not your problem, a friend of mine uses the amber bulbs, they last longer.

I just had the same problem on my '04 Silverado. All it was was corrosion in the socket/bulb. Put some dialectic grease on both the bulbs and worked them in and out a couple of times and now they work fine. Was weird that they both went out suddenly and together but I guess they are made exactly the same.

SOURCE: dome lights won't turn off

Been having a problem with the dome lights on a 99 chevy blazer. Still can't figure out what the problem is. There is a dome light overide button located under the dimmer wheel. When I push the overide button in the dome light goes off, but when I open any of the doors the dome light will not come on. When the overide button is out the dome light stays on all the time and will not turn off even though every door is closed. I checked all the pushbuttons and everything tests good. Has anyone had this problem and know how to fix it?

SOURCE: 02 SS Monte Carlo , dash lights have quit working,

this only occured when the ambient light sensor turned on the headlights when it got to dark. if that is happening then check the headlight switch, the one that also dims the interior lights. mine had a burnt connector and fried the circuit board. replaced it and it works good. check for lose wires and connectors in there as well which likely caused the short.
