Mustang running lights

[Popterrell]

I have a 2018 mustang and on the driver side amber in the front and the rear tail light doesn’t stay on but when I turn my signal on the both work. When I put my foot on the brake the tail ligh lights up. has anyone had this problem or know how to possibly fix it?

Sounds like you have a BCM issue.

What you are seeking is in Post # 25 of this thread for the taillight issue:

You can try disconnecting the battery and see if that has an affect on tripping the BCM to work.
