B Hunter

I have this really messed up problem and its really started to frustrate me. A few nights ago, my headlights stopped working, so I did some research and found out that our cars like to melt harnesses. So i found the harness, saw it was a little burnt up and replaced it. The wires looked ok, but I didnt want to take any chances but guess what, didnt fix my problem, I still have no headlights. I checked all the fuses and everything seems ok. The thing that really has me puzzled is when my car is on and I have the headlights in the full on position, the lights dont work but when i hit the highbeams, they highbeams work BUT the indicator saying the highbeams are on doesnt come on. When I turn off the car and have the headlights on and the highbeams on and the parking brake off, the indicator comes on. To me this sounds like a DRL module problem causing my headaches but I could be wrong. Can anyone help me out?

Thanks
