The daytime running lights go on, but when we pull the knob to turn on the headlights, they shut off. We have changed the bulbs, checked the fuses, replaced the relays, and bought a new switch and still have the same issue. It was suggested that it could be the turn signal switch that controls the brights. That theory seems to make sense because the cruise will not work (fuse good) so it's plausible that there could be more wrong in there. Any ideas from you all? It looks to be a job and a half to get in there to change that turn signal switch, so I really would like to rule everything else out before tearing into it. My son bought this car on Monday and the headlight issue was not disclosed which ticks me off a bit. But it won't pass inspection without working headlights and he is leaving for college next week. So I'm trying to get it fixed as quickly as I can.
