So I plugged up my boat trailer to check the lights. Everything works except the right side blinker and brake light...Looked at all the bulbs on the truck, all are working properly...Decided the easiest next thing was to plug up the utility trailer... Same thing, no right blinker or brake light....Both right and left running lights and left blinker and brake are working....Where do I start ? ...

 

Check your fuses. I don't know about my 07 but my 02 had fuses under the hood that were very specific. A fuse for right brake/turn, one for left brake/turn, one for running lights. Start there.

 

These trucks do have the same thing Fuse #36 or #42 depending on which side is not working.

THANKS ! I'll check it out in a bit...That's got to be it !!!!

 

You're welcome!

 

The #36 fuse is blown....Of course, all I can find around here is 5 boxes of standard size fuses.... I know I've purchased multiple boxes of minis, I'm going to blame my adult kids on this....

 

Haha, little rascals! Glad you found the problem!

 

YESSS !!! That worked !!! THANKS !!!
