Ok, I've looked through several threads on here and I know quite a few people really detest DRL'*, although, I would really prefer to keep mine just as a safety feature. Mine have stopped working. The other day I noticed they weren't on after I had shifted into gear. Plus, my high beams don't flash when I unlock/lock my car. I went ahead and replaced the #30 relay for the DRL'* under the hood....nothing changed. Can someone please help me? I'm stumped! Would the parking brake switch have anything to do with it, by chance? The Twilight Sentinel?

Note: (All my lights at night come on automatically and work perfectly, no problem there.)
