After four months no problems with my Cargo Trailer hooked up I started having light issues. I had to redo the trailer side connections and only got some working. As a bypass I bought a set of magnet lights because I need to get the trailer to recoat my hot air balloon this week.
I plugged the lights in and I get no flasher function on the lights but OK on the truck. The flashers were fine before the problems with the trailer. Is there a particular fuse I should look for? Should I just go drop another $30 on the factory plugin harness? Will that fix it?
There is at least 2, maybe 3 fuses that can be blown. Sorry, I don't have the factory manual handy. I went thru this issue myself with a 11 pro4x. I found the problem in the bottom fuse box. Just going on memory here, look at the diagrams in each fuse box, and check the fuses.
