Check the trailer plug ground first. If in doubt. Ground in another location. Make sure the area is free of rust and the ground is tight.

The left tail light on my trailer doesnt work.the stop and turn signal works . is there a fuse for it? i have 2011 gmc sierra 1500


There is a tail lights fuse for the truck, but not for the trailer.
First, check that your left tail light on the truck is working, if not fix the problem (new bulb, bad contact, fuse).
Then the obvious suggestions regarding the trailer are: Check the tail light portion of the bulb to be sure it is not blown. If good (best to put in new one to be sure), then check the wiring from the front of the trailer all of the way to the non working bulb, including every connection and at any place it is secured to the trailer frame. If all is good with the trailer circuit and bulb, then check the truck's trailer connector, including any adapters. If by chance the truck is wired with a flat 4 wire harness the problem may be solved (but usually the blinkers are the problem). Modern trucks require a 5 wire harness which self adapts to the standard 4 wire trailer circuit. Check for dc power (12 volts) from the truck's female connector. One wire will be ground, others will be taillights (turn on headlights), brake lights (have someone press brake pedal), and blinkers (turn on switch and blinkers).

I need the wiring diagram on a 2004 GMC 7500 Diesel 26' Box Truck. The Tail Lights are not working but everything else is. There is also a beeping like as if the E-Brake is on. Any suggestions?


check the wires in both trailer connections
check that the beep is not from a reversing alarm that is mis-wired in the plug and trailer connection

I have a 2001 GMC 2500HD. It has a Hayes trailer brake controller installed in it. Even with nothing plugged into the trailer wiring socket, the parking light come on when I activate the brake controller....


It sounds as though you have either a frayed wire between the brake control circuit and tail/running light circuit of the truck side of the plug, or someone wired the truck side of the plug incorrectly.

Think about it. The parking brake lights come on when the controller is activated. More than likely the tail lights are also.

The tail lights are also going to come on when the headlights are on. This would cause the trailer brakes to be activated IF there is a short in the TRUCK side of the plug itself.

That's where I would personally start investigating, The truck side of the trailer plug.

Hope this helps.

2004 Chevy Express 1500 keeps blowing trailer light fuse


If you're only blowing the fuse while the trailer is plugged in, the problem is in the trailer/wiring. This takes into account that the truck has a factory installed 7 way receptacle. If that's not the case, the problem can be in the incorrectly wired truck and the trailer is ok.

On the truck, looking into the 7 way receptacle should be as follows.
Top left=Tail Lights
Top right=12v steady source/charge line
Left middle=Left turn/brake
Right middle=Right turn/brake
Left bottom=ground
Right bottom=brake controller output
Center=reverse lights if your trailer is equipped.

Your trailer plug should mirror this.

This is the standard.

Tail lights


You most likely have a bare wire under the truck at the rear where gravel stones can hit, that is shorting out on the frame or another wire. If you have an aftermarket trailer plug, that's the first place to look.

1993 GMC Sierra 4x4, no brake lights, no rear running lights


If you still have this problem maybe this will help. I had to replace the trailer plug on a 93 GMC Sierra K1500 and had a problem with the light's not working. Had to trace wires from trailer plug up to tail lights. The problem was a broken ground wire. It took longer to remove all the tape and replace it than fixing the problem.

Trailer tail lights


I have this same problem with my truck. The U haul guys and I tried and tested every scenario, leaving out hard wiring behind the plug (where the adapter goes). I haven't tried it as I don't ever pull anything, however it can't to too hard to do.
