2008 Buick LaCrosse taillights don't illuminate. Driver information system states "Service Park lamps" when lights are on.
My front parking lamps and rear taillights won't illuminate. Both the front and back will blink when the turn signals are on and the brake lights work, but none stay lit. When lights come on with darkness, the DIC states "service park lamps". I put brand new bulbs in both front and back, and replaced the parking lamps relay in the fuse box with no luck. Any suggestions?
