I've got a 2002 K3500 and have had lots of problems with my headlamps. it all started about 2 years ago, when I realized that my fog lamps didn't work anymore. I didn't think it was a big deal, because they weren't much use anyways. Then about 1 year ago, my left side daytime headlamp stopped working. Somewhere around this time, one of the leftside clearance lights on my fender (dually) gave up the ghost too. I can't help but notice that there are many Chev/GMC tucks running around with only one headlamp working during the daytime, so I'm wondering if this is a natural occurrence, and wonder if anyone has come across the problem and found the cure. Now just last week, the left side headlamp (low beam only)quit. The high beam still works, but people are flashing me when I put them on. I checked the fuses, everything is OK. I haven't checked the bulb since the night time headlamp stopped working, but when it was just the daytime lamp, the bulb was found to be OK. Anyone come across this issue, and do you know what the fix is? I have also moved around the relays in the fuse box, same results, so I don't think that the relay is the cause.
Any suggestions?
