Hello All,
Hopefully someone can help me here. I have a 2022 Silverado Trailboss Custom LTD (same as 2021) that I have upgraded the Headlamp assembly and Grille to the High Country Headlights and LT Trailboss Grill. I have purchased and installed the Gen5DIY Harness to control the lamps and the Hi/Lo headlights work properly, as do the turn signals and parking lamps, but the DRLs blink 3 times in sequence (Full LED area first, then mid and lower section and finally just the lower section) before shutting off completely. This happens every time I from Park to Drive, Park to Reverse, etc. Initially, I had thought the issue was with the harnesses, so I had swapped the harnesses (Gen5DIY was gracious enough to send out two new harnesses to swap with) but that did not correct the issue, I had also purchased (2) new sets of control modules and neither set corrected the issue. I finally left the car battery unplugged for 2+ hours in hopes of clearing the ECM/BCM (long shot) but that didnt work either. Currently at a loss as to why this is not working when there are plenty of others that have performed this mod with no issues. I have created a link to the video showing the issue. https://photos.app.goo.gl/nADAnqi4UPe1zJ1BA
I have scoured the web in search of possible solutions, but the common result for "blinking DRL" or anything close to that is likely someone looking at DRLs through a camera or aftermarkets that blink with a turn signal.
Prior to swapping out the headlight assemblies, I did have LED bulbs in the original halogen headlight housings. the bulbs were S-V.4 LEDs and then the GTR Ultra bulbs. Wondering if that could have done something to the BCM maybe?
Hoping someone has some insight as to what the issue could be. Thanks!
