So from my research........they should work.

I just installed them and nothing. I was not expecting the puddle lights to work, but the signals are inop.

So reaching out to the public for assistance.

Thanks in advance

I tried figuring this out myself months ago. Even sent my bcm to whiteautomedia to have it flashed for the features and still didnt work. I ended up taking it to an audio shop and having them wire it up for me. Signals work. Puddle lights only work when the door is open.

I have a buddy that's an electrical engineer and has work heavily with GM and SRT programs.

I'm going to see if a reflash would work or if I should looking in to getting an LTZ BCM and having the VIN reflashed to work

the blinker function would come from the door switch, check for the blinker signal at the door switch harness there are 2 of them that go to the mirror from the door switch one will have the blinker function and the other has the puddle lights, puddle lights will only function after dark and with the oem keyfob and with the approach lighting enabled in the dic.

Everything plugged in the drivers/passenger door switches as expected (1 black connector and 1 white connector)

Still no dice at the moment......... AS far as the entry lighting, never checked my DIC LOL

if you want to test the puddle lights during the day just throw something over the sun sensor on the dash like a shirt or a rag.
the signal for the blinker should be at the door switch plug, it's possible they may not be present from the bcm to the door switch in which case you could just run wires from the bcm to the mirror harness, or replace the harness from the bcm to the door switch from a non ppv junker

I check every option in the DIC......nothing for entry lighting. Guess I need to have a new BCM flashed with the VIN from my old LTZ OR make the trip to the dealer
