Hello,
I'm looking for the location of the fuses for the stop lights .
Thank-you for your help.
Regards.
I am looking for the stop light fuse in my 2019 3500 Mercedes sprinter. thank you.
2023 Sprinter 2500 relays are not in the right footwell. That is occupied by the jack tools. Sigh.
They are underneath the tool holder.
