Drivers Side Tail Light Fuse Blows Again on Chrysler Town and Country with Curt Wiring Harness
Question:
2014 ChryslerTown and Country Mini van 2inch Curtis hitch and wiring harness. This is the second time in 3 months this has happened. The first time was this past spring. You replace the harness super fast. With out my small utility trailer hooked up, I suddenly I start blowing my left Driver side tail light fuse I know I might get stopped for this one day humph! Anyway you sent me a replacement as these were guaranteed for a year, I would be odd for the control box to be bad twice. So Im back to square one The only problem I can find is the ground screw was a little loose, Would this be a fault area ? Have you had any one else with this same problems on their Town and Country Vans

The chance of receiving two faulty converter boxes is very low and we have not had any recurring complaints on trailer wiring harnesses for the Chrysler Town and Country or Dodge Grand Caravan minivans. A blown tail light fuse could indicate that the converter box has shorted out allowing power to back feed onto the tail light circuit. The main causes that we find for faulty converter boxes are short circuits on the trailer, excessive power draw, and faulty installations.
Before installing another wiring harness, I recommend looking for a short circuit. This is usually a broken, frayed or pinched wire that may be coming in contact with the trailer frame or another circuit. Start at the trailer connector and follow the wires back to the tail lights and marker lights and pay attention to areas where the wire passes through something or has a splice. I would also inspect the trailer connector and splices for signs of corrosion.
I doubt excessive power draw is a problem your small utility trailer. This issue usually arises when trailers have too many tail lights and clearance lights. Also, a loose ground should not cause a fuse to blow. It would merely act like an open circuit rather than a short which would just cause the trailer lights to stop working properly.
If everything on the trailer checks out, I would look at the installation of the harness. Check the wires to make sure they were not routed in a way that they could rub against a sharp edge or be pinched. If the converter box was not secured and is hanging or moving freely, the internal connections could come loose as it moves around while you drive. They come with double-sided tape, but I like to zip tie it to a solid structure to make sure it cannot move.
