When I purchased 6 months ago I changed out the headlamps with new stock lamps. Everything worked well for a long time. Lately, however I've been having issues with the head lights. At first they would come one then moments after starting a drive they'd go out, but I still had DRL. A few days later, they would come on but my highbeams wouldn't stay on. Now I have neither headlights or DRL. I changed the fuse and there was no change. I put a recycled DRL module in and got my DRL back but still no highs or lows. Dash lights are unaffected. I'm told it could be either the module or the switch. I pulled the dash apart (in order to put a new stereo in) and all the wiring looks good. There is nothing exposed, fried or otherwise damaged. Any other suggestions before I hand over $200 for such a small part?
