When my running lights are working on my trailer my turn signal lights and brake lights don't work but if running lights are off turn signal and brake lights work?

Why does your left side trailer blinkerbrake light not work on your Avalanche The right side trailer lights work fine as do all lights on the truck itself work fine. There's no 12v at the 7-prong.?

If the Avalanche came with the factory trailering package, the trailer lights are separately fused from the other truck lights. Check your fuse panel layout for a 10-amp fuse for left side and a separate fuse for right side turn signal/brake light on the trailer.

How to fix boat trailer lights Both blink while left turn signal is on Tail lights work ok when head lights are on and when right turn signal is on?

Check ground circuit Check bulbs they are duble filamented one may be burned out Seems to me there is a wire crossed at the harness. I think the vehicle left turn signal wire is hooked up to the trailer tail lights wire. Usually there are four wires at the trailer harness, yellow, green, white, and brown, The brown wire is usually the tail lights and side marker lights, the white wire is ground, the yellow and green go to the left and right signal lights.

Left turn & stop on the tow pack wires - yellow Right turn & stop on the tow pack wires - green Left turn & stop for vehicle lights - green with a orange stripe Right turn & stop for vehicle lights - orange with a blue stripe There is a secondary fuse panel under the hood that controls the tow pack wires only.
