Any one had the problem of blowing trailer towing fuses? I've tried three diferent trailers and three different harness and still blowing the right trailer fuse. This truck is less than 1 year old. The dealer says it has to be a problem with my trailer wireing, but three different trailers tells me it is a problem with the truck.

 

Went through one fuse but it was the trailer. so far no wiring problems even with the boat launch multiple times.

 

I tow several different trailers often and have not experienced any lighting problems, maybe check the harness on the trailer sometimes a pinched or bare wire can short out.

 

oops on edit...should learn to read, so you have tried several different trailers and the same thing happens....hmmm sounds like it might be with your truck wiring harness for your trailer.

I had a problem years back with my Super Duty blowing fuses so I took it to the place I bought my trailer from, the installer hooked up some gizzmo into the plug on the back of my truck to see if I had any kind of short in the wiring harness...i didn't but I did have corroded socket which he replaced and all was good after that.
