Fuse under the hood for towing lights?

We pull a 6'x12' concession trailer with our 2003 Chevy Express 1500. The tow lights (exterior, brake, turn signals) are not working on the trailer. We have replaced the whole wiring set-up between the van and the trailer and have replace fuses in the trailer. Does the van have a fuse box under the hood that is for towing?

SOURCE: LEFT TRAILER TURN SIGNAL DOES NOT WORK

I'd get a 12vdc test light if you don't have one already & start from plug, and keep probing back from there. It may be as simple as a bad connection under truck where joined into harness.

SOURCE: brake and turn signal lights stopped working on my 1996 Ford E150

You might have cut a wire or it could have broken or disconnected. Try tracing the wiring where you hooked up the trailer you may find one broken or disconnected.

SOURCE: Fuse for trailer right turn signal and brake blows intermittently

abad ground on that tail light unit could affect current load when turn and stop are used simultaneously. Although one side only is affected make sure of good grnd between trailer and tow vehicle. focust on the tail light unit in question. Replace the bulb. though rare, bulbs have been known to be the problem. If the bulb is breaking filiments ck the filiment orientation. filiments last longer in vertical orientation, where horizontal permits vibration to break the heated filiment when brake is applied.. good luck and let me know if This helped or not.

SOURCE: I have A 2000 Chevy 3500 Express Van and the brake

Hi,

When you said that you checked the brake switch, did you check it live? Meaning verified live power to the switch, press switch, and then power came out the other terminal?

If so, also verify zero power on brake press, at the offending brake light bulb terminal. You must verify the test light each time you move it...leave running lights on...

After verifying that there is no power coming, after the brake is pressed, note the wire color and find it where it comes to the steering column and test there... This would eliminate wires and connections between front and the rear of the vehicle, unlikely, but needs to be tested.

After verifying no power at that terminal, then yes the t/s switch is certainly suspece. This may be the time to get a mechanic to verify and replace the switch, there are locks, tilt mechanisms, air bags, column bearings, etc involved. Failures risk loss of vehicle control (locking or binding for example.)..

Hope this gets you going in the right direction.

SOURCE: LEFT TRAILER TURN SIGNAL DOES NOT WORK

I have seen once before that the fuse box was bad on a 2003 Dodge 3500. I had power in and nothing out. We had to replace the box. Not cheap! Hope it is simple like a loose connection though. I think I had to pull the inner fender on the drivers side to access the bottom of the fuse box. Pain in the ****, but...

Brake light dont work. 2006 chevy truck, 4.8L 2wd


Some of these had two fuses for brake lights. One for the top/center stop lamp and another for the rear left and right brake lights. Usually one said "stop" and the other said "brake" and one was in the underhood panel while the other was in the dash fuse panel. It's not uncommon to blow a brake light fuse [LR and RR] if you tow a trailer but some of these had seperate fuses for the trailer lights also. If you have a test light check both sides of the two fuses for power [ignition key on] while stepping on the brakes. It should at lest narrow your search a bit.

I have a 2008 Ford F 150 with factory installed trailer wiring. I bought a trailer plug tester. It shows the tail light function to be dead. Brake lights, turn signals all work. Any ideas?


The trailer tow adapter parking lamps is fuse #10 in the cab fuse panel. There is also a trailer tow parking lamp relay that powers them, which could have a problem as well.
Start with the fuse, and maybe check both the 7 pin and the 4 pin for the parking lamps, could be a corroded pin on one of them causing the tester to not see the power on the pin.

I HAVE NO VOLTAGE AT THE TRAILER CONNECTION


There are a few fuses for the trailer tow adapter.

1st, is the odd location on the 97-98, engine mini fuse panel has a 20 A fuse for the stop / turn lamps. Have seen it covered in tape from the factory on some 97 MY trucks.
This is on page 142 in the owners manual.
If you see one, you can download a PDF version from Ford at :

https://www.fleet.ford.com/maintenance/owners_manuals/default.asp

The others :
1. Power Distribution Panel / engine compartment fuse panel
Fuse #1 - Trailer tow back-up and tail lamps
Fuse #16 - Trailer tow battery charge and stop/turn lamps
Fuse #28 - Trailer tow electronic brake

2. Instrument Panel Fuses ( cab fuse panel by hood release )
#23 - trailer tow battery charge relay

I found the problem. Talking with a technician from the controller company, we determined that it was a fuse problem. I found that the fuse to the CHMSL was blown.

No power to tail light on trailer- 2004 Dodge durango factory tow


If this is a factory light harness for the trailer hookup on your Caravan. Look under the hood for a fuse box. Many 2000+ vehicles have this with separate fuses just for the trailer lights.

I only have taillights coming out of the trailer plug


so, the trailer has no brake lights, or turn signals, just tail lights? Everything (all lights) on truck work ok? What do you have for trailer wiring hook up 4, 5, 6, or 7 way? There is no fuse, the lights all work off the tow vehicle lights, so if the tow vehicle lights all work properly, it's probably a wiring problem, such as bad grounds, loose connections, etc. Get a volt meter and check voltage at truck plug to see if power is getting that far. If truck plug in is ok, wiring problem is the trailer. Make sure all grounds are tight and rust free, that's a common problem.

2009 chevy expres trailer wiring harness


Ask dealer if it has a towing package on it. If it does, you usually just pop fuse in under hood for electric brakes, and harness to adapt into is usually near or at rear bumper. Even if it doesn't have brake wire, you should still be able to install adapter at rear,for lights etc. which is available from dealer or auto supply places, then you may have to run electric brakes separate.
