Where Are Trailer Light Fuses Located At on 2021 Ram 2500
Published 12/08/2022 >
Question:
Wondering what fuse I should check if my trailer brake/turn signal lights on the drivers side of my 2021 Ram 2500 are now working. It’s not the trailer because it’s happening on more than one of my trailers.

The trailer fuse locations for a 2021 Ram 2500 can be found either in your owner's manual or on the underside of the fuse box lid. I have attached them for you below as well.
