What's up guys? I'm having an issue with my 2020 transit ecoboost I did A diagnostic on my vehicle and rear turn singles aren't working and brake lights. The front tern signals work but are blinking rapidly and the diagnostic said to change out the rear lighting control module. B and i'm not too familiar with any of this can anyone help ? Thanks in advance

First thing to check is the bulbs. Make sure they're good.

Do you have a trailer hitch on there, Did you wire the lights yourself? Thats where the problems start.
The fault code might help.
