Sounds like a bad ground. I just read on here over the weekend about grounds being a common issue due to the unseen corrosion in the connectors. May try moving the wires on the chassis ground connectors and see if you can identify it.

I've got a ton of 12Volt eperience(In another lifetime , managed a Circuit City roadshop , first class MECP cert ) and GM's are notorious for ground problems , I've encountered this on many vehicles and it always seems to be under the dash somewhere .

I had a simliar problem with dimming headlights while operating the power windows on my '99 coupe. A couple weeks later, my battery took a dump on me. I would check the battery first. JMHO.

If it is the battery it is likely a bad connection on the battery. Would not expect that the car would start if it was going to have a noticable affect on the lights. If it seems to do it on the bumps instead of smooth ground, then I still suspect bad connections somewhere.
