I have a weird problem with my headlights when its cold outside during the winter. When I pull the lights switch to 'ON' they wont come on right away, usually it takes a few minutes of driving before they switch on. I tried flicking the high beams on but they wouldnt come on either. It only does this when its cold out too, during the summer/ warmer months they switch right on. Any thoughts? Bad switch, bad relay? 97 sport.
