I have a 2008 Grand Prix and within the last few months I noticed my high beams would flicker for what seems like a millisecond. Two months ago I replaced the relay because my low beams went out completely and I thought that it fixed my high beams as well because I dont use them all that often , but I had an oil change done yesterday and they also did all sorts of checks on the car included. It seems like afterwards my high beams are flickering again. Not sure what happened but any idea how to fix it?
