Trailer Fuses
If a trailer light is burned out, check if these fuses are blown up when you have replaced the light bulbs:
- Primary under-hood fuse box fuses 5, 7, and 24
- Interior driver’s side fuse box: fuse 10
- Interior passenger’s side fuse box: fuse 10
- If those fuses are OK, but the trailer lights are still not working, check the two 7.5 amp fuses in the trailer hitch wiring.
To access the 7.5 amp fuses:
- Open the tailgate and remove the cargo floor lid.
- Pull out the bottom of the tailgate rubber seal.
- Remove the rear trim panel by pulling up on the inside edge of the rear trim panel, and unhooking the four clips and tabs.
- After replacing fuses, and reinstall the rear trim panel in the reverse order of removal.
