I have a 2016 Freightliner Cascade. The truck keeps blowing fuses ( blowing within seconds of putting) for the trailer running lights. I still have brake lights and 4 ways and clearance lights. Any ideals. I have done everything I can think of.

You have a short somewhere. You will have to find it & fix it.
Bakerman and Annwhite71 Thank this. -
if it doesn’t, then the short is likely to be on the trailer side somewhere.
Check anywhere light wires pass through o rings/ metal, where they make bends and etc... if you’ve gone through salted roads lately, I would look up around wherever the tire spray would be. Then inspect those wires, if not covered real well, they could be ate through and wire exposed. At this point the exposed wire could be touching metal grounding out and popping the fuse.Annwhite71 Thanks this. -
I would plug in to a different trailer and see if it still does it. If is doesn't, the problem is in your trailer.

yes try a different trailer. if it's specific to the trailer, open up the box on header of the trailer, chances are something rubbed through in there. Get a powerprobe and try supplying juice to the trailer manually on the correct pin, see if it pops the breaker on the powerprobe, open the box, try again, see if you can see or hear the short. Some trailers split the clearance lights so there's 2 sides that come together, then try and isolate which side it's on if it's not in the box. pray it's not hidden too bad. Chances are it's in the trailer.
