I was working in the yard all day today getting the weeks worth of fallen leaves up off the lawn. I also cut a few low hanging branches from some of the maple trees in the yard. I worked up a pretty good appetite so I decided to drive into town ( I live in a very rural area ) pick up something to eat and run a couple of errands.
When I got home I pulled in the garage as I always do, I usually leave the garage door open when I'm not going to be gone long. As I pulled my 99 K1500 all the way in I noticed that it was darker than usual in the garage. Took me a second but then I figured it out, the day time running lights weren't on. The green light on the dash was still lit but no DRL's. I turned the lights on and off several times, they work fine. I shut the truck off and restated it a couple of times but the DRL's stayed off. Mine is the early 99 that uses the low beams for the DRL and they aren't burnt out.
I guess they may come back on as mysteriously as they went out but I hope they stay off. I was going to look for the ignition sensor wire one of these days that turns them on but I guess that I don't have to now. Has this happened to anyone else? I sure hope it's not something on the way out. I can't imagine what though.
