    I just developed a little (hopefully) electrical problem with my headlights and rear running lights. Hopefully, one of you folks have either had or maybe know what my problem is. I found out that my dim headlights do not work along with my rear running lights. When I hit the dimmer, it get high beams. My brake and turn signals work. I assumed it was probably my light switch so I replaced it. No fix. Then figured it was my dimmer switch which I replaced. No fix. I replaced the dash wiring harness about 6 or 7 years ago so it seems to be in pretty good shape. Does this sound like maybe a short somewhere or another electrical component giving me grief? I also completely rebuilt my steering column/turn signal switch and wiring a couple years ago. Any thoughts or advise would be greatly appreciated. On the bright side, I can still drive it during the day!
