I tow a 5th wheel and the right rear turn signal and brake light are not functioning on the trailer. I used a light tester and found the prong that controls this function onmy trucks plug has no juice. Now, do I replace the entire plug or is there a fuse that controls this function? Any help would be appreciated.

 

mayers, I'm going to take a guess it's a fuse. Drew or someone else will be able to answer for sure, but I think i remember a thread earlier that mentioned there are fuses for all that. there might be a secondary location too......

 

There are fuses in your fuse box that control trailer light functions, I'n not sure about them being left or right specific though, check the fuses first, they are labeled well.

You might want to look at this TSB.

 

I'm lookingfor the specific fuse that controls this function. I'd like to start there. Thanks

 

That's the problem. As I understand it, there is no fuse. It is a problem with the Total Integrated Power Module (TIPM). Take it to the dealer.

 

yes there are fuses in your fuse box. There are fuses for left turn, right turn and trailer lights. I blown one once.
