Trailer 7-way Plug no longer working

sheamus said:

I don't seem to have any power on any of the pins on my 7 way RV plug on the truck. It is a 2015 p4x auto.

There is an interior fuse box, and two under the hood. On the fuse box under the hood, and furthest back, there is a 30A fuse marked TOW, but it looks to be fine. Are there any other fuses I should be checking?

I had this same issue and started to test all of the fuses. I honestly forgot which fuse (or maybe relay, I forgot) it was, but there was another one that seemed completely unrelated that was blown and it fixed the issue. Buy a cheap tester and test them all under the hood - only takes a few minutes.

It was under the hood though?

A fuse I can test with my multi-meter, not sure about a relay... Thank you.

Definitely under the hood - trying to think what it was labeled - maybe it was REV or something - sorry. Somewhere here I posted it, but that was many moons ago. Anyways, should only take a few minutes with your multi-meter.

My search skills are at level ninja this morning. Found the post from a few years ago: http://www.clubfrontier.org/forums/...tall-hitch-pics-27530/index3.html#post2458322

Woah nice. Going to pop away from desk and try this quickly. Thanks.

Let us know if that does the trick. Electrical issues are not my favourite to sort out.

So when I started digging, I realised there was a whole other board of fuses on in that large box at the back/under hood. That board actually had a few more smaller trailer fuses. I think I had only found the large 30A one. Turns out the F4 (tow trailer) fuse was blown. I stole the F2 RR Def fuse and put it in F4. I tried my trailer test plug and got nothing still. But I didn't have time to try anything else.

Won't have time tonight, but tomorrow I'll try unplugging the trailer plug from harness and see if I have power back there. It is possible trailer plug was not wired correctly.

Finally got around to testing. Shop had wired trailer up wrong. After I sorted that out, I tested and everything is fine. So I can confirm for me it was the f4 fuse. Thanks for all the help.
