Hi Jean,
There's definitely some testing that you can do to narrow down what the issue is and get it fixed. We'll just need more info here on your setup to figure out what troubleshooting steps you should take. What type of brakes does the trailer have? Have you tried this truck out with any other trailers to confirm it's the truck that's the issue and not an issue with the trailer? Does the trailer have LED or incandescent lights?
