'15 GT tail light issue

[JackBauer]

so i have the taillight issue that plagues these cars where sometimes 1 of the strips does not want to work when turning the blinkers until i restart the car.

option 1 to fix is pay $100 some odds to the dealer to refresh the BCMB this supposedly has worked for some and not for others.

option 2 replace the BCMB hopefully from out of a newer car with the correct fix, these can be found on ebay for $40ish or so.

i want to go with option to but what i need to know is...is this a easy replace and be done, or does it need to be programmed? if it needs to be programmed can I do this with Forscan?

to add ive searched around the forums and some people have replaced theirs but they don't specify if they had to re-program it for their car.

Hello, Ik it’s been about a year, just replaced my tail lights thinking that was my issue but seems the new tail light still doesn’t work as it should. Did you found a solution? I was about to check all my wires to see if anything is damaged and since the new tail lights came with new harness then it’s for sure the harness coming from the car that is damaged or bcmb.

Mine was filled with water, check for moisture.

I have to check the harness coming from the car. The tail lights are brand new. I replaced them for the same reason.
