TJay74, Understand that the led strips are my DRL's. They both illuminate with headlights on, they both illuminate when remote started and when fog lights are activated. They will not activate when truck is running in or out of gear, during this time there is no DRL green symbol illuminated in my instrument panel either. Only the bottom LED strip should be on for DRL or at least that is how my truck was.
Moto-Medic, the only work performed on the truck was the installation of the power tail gate lock. I thought about that but I did not damage any wiring, the locks functions fine, and I unplugged it and retested, no difference. I guess in theory I could have done something to a wire in that bundle under the door sill but I was extremely careful when moving them.I checked the manual for DRL operation and fuse locations. None of this helped as I could not find any fuse for DRL, just headlamps, park, tail etc. Which I saw in a few posts on here that the fuse was removed by GM. I did look in the fuse panel at many fuses for a blown one, but would almost have to pull them all to be 100% sure. I have tested all lights, blinkers, bed led's, various options and I cannot fine anything else not working. One other item to note is that I am not sure when this happened as I think I had gotten used to the green dash light and pay it no mind normally. I had also not used the truck regulary for the last few weeks making it even harder to pinpoint.It could have been this way for the past month. I was seeing them light when I remote start leaving work. Just glad at this point that I noticed it because I am finishing the HID conversion novel and wanted to order the DDM kit this week. Also the green DRL dash light lights upon startup as if all is fine with the system then goes out which is normal until you place it into drive. I cannot think of anything else to try at this point. Seems odd that they are the only lights not working, software glitch? failed relay?
