Troubleshooting Trailer Running Light Fuse of Vehicle Blowing on 2010 Honda Pilot

Updated 07/13/2020 | Published 07/09/2020

Question:

So I have it traced to the 20 amp fuse blowing in the rear driver side fuse box. I replaced it and it blew again right away. 2010 Pilot, with a mitsuba unit, RK00-451. My running lights are not working so I am guessing I have a short somewhere? 1997 Coleman Santa Fe

Yes you definitely have a short on that circuit's wiring. If the fuse blows without a trailer connected the issue is on the vehicle side of the wiring, if the fuse blows when the trailer is connected then the issue is the wiring on the trailer. You'd need to go over the wiring looking for any cut or exposed wire and fix as needed.

I attached a help article on trailer wiring troubleshooting for more info for you to check out as well.
