OK, you brainiac's..

Got a problem with my trailer lights. The whole left side of lights are dead. I haven't checked anything yet. I'm asking where to start and what to look for.

Find where the sides split. Most likely the connecter

Gewber

Or a bulb burned out on that side.

You calling me a gewber? That's worst than the kettle calling the skillet black.

Look under your hood on your truck.....there is a big black box that should say main load center or someting like that.....take the lid off of it and there are a lot of fuses in there look and you will see trailer lights, left side and right side......this is what I would check first. The fuse panel inside your truck cab has fuses for the truck lights only.

Just a side note, on my old 07 GMC 2500 and my new 2010 F150 the trailers light fuses are in the inside fuse box on the passenger side. Had to hunt them down on both

Morris, Take the Thingamabob off and check the dooflotchy. If it's loose, I bet that the lights not working is cause by the whatchamacallit not getting a connection. Hope that helped

Holis on your model truck I think your trailer fuses are under the hood. After you check that, start at your brake light and go forward to the connector to see if you have a bad spot or even a broke wire. I had a brake light ouy and it looked like something off the road jumped up and broke the wire right at the light.

Loose wire
