Fuse for trailer lights keeps blowing!

The fuse to my trailer lights keeps blowing. I was wondering if anyone else has had this problem. I have the Curt wiring harness.

If it is a factory harness, then the only load is the trailer lamps...having said that--there are--on the older ones--three relays that are "picked" by the vehicle lights that then switch the current to the trailer circuits. If something has gone wrong there--that would be the first place I'd look. Does thw fuse blow when a turn signal is used, the tail lamps, etc.?

I have the Curt harness. I just threw another fuse in and discovered that the passenger side trailer brake light stays on even if I don't have the brake pressed and the lights are off in the Jeep! 😳

My guess is the tail light converter has gone bad. I've replaced two of them in different vehicles they do weird things when they go.

Easy check is to bypass the converter and see if everything is normal.
