Ok, Today I finally had the chance to work on the car. DRL lamps were working before I started. Pulled headlamps and throroughly cleaned grounds. I sanded frame area to clean bare metal, sanded both sides of the connection to a shinny copper color, and even used star washers on both sides of the connector to make sure I had a good contact when I torqued down the bolt. I had to check fluids so I had the car running and lights were on. As I was checking fluids (about 5 minutes later) the DRL's went off...just like that! I worked the light switch on the turn signal stalk, and even swapped out the DRL relay with a new one. No Change, lights were still off...and are right now. I should say that one thing I noticed is that it did get dark during the time I described above. Also just tried them now and still no headlamps...

ANY IDEAS of what to do next??
