I recently had all of the bulbs replaced (11) in my instrument cluster on my 2005 Saturn L300, by a Chevy dealer. It appears that the gauge cluster is missing some overhead lighting because while the gauges are backlit I can't read the indicator needles. I believe there are 2 overhead theater lights are not working. There are 2 slots at the top of the panel housing where it appears light passes through and lights the front of the gauges. The dealer tells me I'm crazy and that there is no theater or overhead lighting, only backlighting.
