Where are the Towing Light Fuses on a 2015 Jeep Grand Cherokee

Question

Question:

I have a 2015 Jeep Grand Cherokee with the factory tow paakcage installed. Recently I hooked it to a trailer that had damage to the wiring. After blowing a couple of fuses, replacing them all, I no longer get power to the lights turn signals and brakes work fine. Am I missing a relay somewhere or something other than a fuse?

I checked the owner's manual for your 2015 Jeep Grand Cherokee and found all of the locations you need to check that relate to the trailer lights. There are several so it is certainly possible that you missed a few but I don't see any relays. These fuses are all located in the power distribution center (PDC) or aka fuse block under the bonnet next to the engine. There may also be fuses in the interior fuse panel but I was not able to look the locations up for you.

F29 20 Amp Blue – Trailer Tow Parking Lights
F30 30 Amp Pink – Trailer Tow Receptacle
F53 – 20 Amp Yellow Trailer Tow – Left Turn/Stop Lights
F81 – 20 Amp Yellow Trailer Tow Right Turn/Stop Lights

Please let me know if you need further assistance.

@MarcusS Hello Marcus. I am sorry to hear there are issues with your right blinker. It might help to use something like the Hook Probe Circuit Tester # PTW2993 to help finding where the issue is. Good idea to check the trailer so you can rule that out if you find it is in good working order. Let me know how it goes.

@KateF hello I’m trying to figure out what wire is my reverse wire for my trailer plug in I’m trying to add pot lights to my reverse lights with the trailer wiring instead of using my tail lights. If you can help me that would be great thank you.

@MarcusS I attached a help article where you will be able to see how the 7 ways are normally wired. There isn't a real standard when it comes to trailer wiring, what I do is just match function to function buy using something like the Hook Probe Circuit Tester # PTW2993 to test the function of the wire going into the 7 way. Don't ever try to match the colors, there isn't a real standard for wire colors either. Maybe one day they will come up with a standard to all this, take all the guess work out.
