Sure sounds like a blown fuse. Who did the trailer wiring? You?
Have you checked your Owner's Manual?
If I go directly to the Index in that Manual and look up "F", I find
"Fuses" at the bottom. I flip to the specified page and I'm directed to
another page which has the fuse box diagrams and the fuse descriptions.
By simple process of elimination, I determine that the ones marked for
"Small lights" are most likely to be associated with the taillamps. There
are several, so check those carefully.
If you do find a blown fuse, check for a botched wiring job.
Carefully read the section on fuses in the owners manual. Worst case if
nothing jumps out as being the obvious choice, check all lights related
If it blows again real quickly, whomever installed your trailer harness
probably messed things up. If replacing the fuse is good for now, make sure
they are still good when you hook up the trailer again.
Problem solved. I replaced the 7.5 amp "Small Lights (exterior)" fuse
and all is well. My problem was that I expected to see a fuse labeled
"Tail Light" or something more obvious than "Small Lights". Also
checked the trailer and found a crossed ground wire. Thanks all.
