Hello! I recently bought a 2010 Tahoe LTZ about a month ago. I swapped out all 4 bulbs in each tail light for LED bulbs, I swapped the front turn signal/running lights to LED bulbs and the DRLs to LED, as well as all interior lights, entry lighting (Under Mirror) and license plate bulbs. The lights flashed quickly after install, so I fixed that by installing resistors at each light (total of 4). Now I have a weird problem, and I'm not exactly sure when it started but I can't figure out what is going on.
When the head lights are on, or I am stepping on the brake, all the signals work perfect. However, if head lights are not on, and I'm not stepping on the brake, when I signal, it makes all 4 signal lights flash, both fronts and both rears. It looks like I have my emergency lights on. The Turn arrow in the mirror will only flash on the side I'm signalling, but the 4 corner lights will all flash.
In the rear, both the upper and lower red lights flash, as well as the small 194 bulb down in the bottom/side. When I step on the brakes, or have the head lights one, only the bottom bulb flashes in the rear (bottom 3157 bulb).
Also when all lights are flashing, the license plate bulbs flash with them. I can't figure out what's going on for the life of me, I swapped out to normal bulbs, or even no bulbs on one light, and it does the same thing, tried disconnecting the resistors, problem persists. Looking for any ideas. Had a buddy who works at a shop look at it last night and he thinks it might be something in the BCM or the turn signal switch. Any help is greatly appreciated!
PS I suck at explaining stuff, so let me know if that doesn't make sense!
