98 Bonneville that I just bought. When I put it in drive ALL of the lights come on as though it thinks it is night time, even in the bright sun. I understand that the DRLs should allow for the headlights to come on with reduced power, but the tail lights, instrument panel lights, etc all come on full strength as if it is dark. Any ideas? Thanks.

More then likely your daylight sensor on your dash is either really dirty or needs to be replaced. Make sure there is nothing sitting on the top of your dash covering it.

Cool - thanks that led me in the right direction. I thought it was the sensor in the middle of the dash but found out it is actually on the left side near the VIN plate. I now know what happened. While scraping off an old inspection sticker I hit it with my hand accidentally pushing it down the hole. At the time I thought it was just a plastic plug. Now I have to figure out a way to get it back out.
