Thank you, problem solved! Just left work for lunch and found a reflective window... Sure enough, mine are working now. It could have just been needing the new bulbs the whole time and replacing the fuse and relay were an unnecessary step? What a simple thing to not know about when troubleshooting, make sure it's in gear and not in "park"
Just left work for lunch and found a reflective window... Sure enough, mine are working now! It could have just been needing the new bulbs the whole time and replacing the fuse and relay were an unnecessary step? What a simple thing to not know about when troubleshooting, make sure it's in gear and not in "park" . I also read that the parking brake cannot be engaged, must be in gear and no parking brake for the DRL's to come on.
I'm having the same issue with my DRL's not working. Swapped out the bulbs, fuse, and relay and still couldn't get them to kick on. I just learned today from another forum member about the gear selector needing to be in "drive" for DRL's to turn on. I've been testing them while it's been in my driveway so it's been in "park". I'll have to go find a reflective window somewhere and see if they're on when in "drive". I've never had an issue with my taillights not working though (that I know of).
DRL's didn't have bulbs installed when I bought the truck used (2002 Sierra 1500 HD) and I'm starting to figure out why. Installed new LED bulbs and they didn't work. Tried the standard OEM replacement bulbs, nothing. Replaced the fuse, nothing. Replaced the relay, still nothing. Any thoughts of what could be wrong? Possibly the actual sockets themselves that hold the bulbs could be shot? If that's the case, it just seems odd that they'd both go out. They are a bit burned and/or discolored but from what I've read that's a common issue and doesn't necessarily mean they're "damaged". Thoughts?
