2013 F-150 Trailer Lights Not Working: Fuse Issues?

I’ve also heard that the trailer lighting system can be sensitive to voltage. Have any of you experienced poor performance after changing batteries?

Yes! Sometimes, a weak battery can lead to inadequate power for the lights. It’s best to test the truck battery, too!

I wish it was just a battery issue! I’ve had to replace my entire wiring harness due to corrosion. Costly and frustrating!

Ouch! That’s rough. What did you do in the meantime when lights weren’t working?

I just used a flashlight tied to the back of the truck for night driving! Not safe at all, but it got the job done until I could get it fixed.

That’s one way to get creative! Just remember, safety first! Have you managed to get it fixed yet?

I had a similar issue with my 2013 F-150. It turned out to be a fuse problem. You might want to check your fuse box under the dash and in the engine compartment. Look for a fuse labeled for the trailer lights, usually a 15 or 20 amp.

It’s definitely worth double-checking! Also, make sure you have a fuse puller handy. It makes the job easier and safer than using pliers.

Don’t forget to turn off your ignition before working on the fuses! It’s a good safety practice to avoid any electrical shorts. You might need a multimeter to check if the fuse is blown.

Great point, craigruiz! I learned that the hard way – shorted out some wires when I forgot! Double-checking the fuses can save you a lot of headaches later.

In terms of tools, you’ll need a basic socket set and a multimeter. Also, bringing along some replacement fuses (15A and 20A) would be great just in case!

If you’ve replaced the fuses and they’re still not working, have you checked the connector plugs on the trailer side? Sometimes corrosion can cause issues too.

That’s a good point! I had that problem as well. Cleaning the connectors made a huge difference for me!

I’ve replaced fuses before, but I didn’t realize that the trailer light fuses were different types! Can you use any blade fuse, or are there specific ones for the trailer lights?

Good question, christina89! The trailer light circuit typically uses standard blade fuses, but always check your owner’s manual to confirm the rating!

I almost forgot – if you suspect the trailer light fuses might be fine, could it be an issue with the trailer itself? Maybe test with a different trailer if possible.

Honestly, all this talk of fuses makes me feel like I need a fuse for my brain. Maybe just get a mechanic to do the dirty work after all, haha!

Funny, ujackson! But seriously, if you’re not comfortable with it, there’s no shame in asking a professional! Safety first!
