I was not sure where to post this, so I thought I would start here. I was hooking up my camper to the truck today, and my son said that my trailer lights looked "weird". I told him to stand behind the trailer and help me do a light check.
I unplugged the trailer from the truck, and then plugged it back in. All the running lights work perfectly.
I reached in the truck and put the brakes on. My son said both back brake lights brightened.
I put the right blinker on, and it worked good on the truck and trailer.
I put the left blinker on, and it only works on the truck. The back tail light on the trailer does not flash.
I then looked at my dash, and noticed that my information center said "Service Trailer Brake System" on it.
I have the GM integrated brake controller in my truck. So here is my question. Does this system warning mean something is wrong with the trailer brake system on the truck, or the trailer? And how do I go about figuring that out without having to spend money at a dealer?
Sorry if this is a simple thing to look at and fix. I am not real familiar with electrical systems. I just want to make sure I have brakes when I pull to the campground this weekend.
Thanks in advance.
