I have a 1983 terry 30' trailer. A while ago when I first bought it the brake lights and turn signals did work, now I'm facing the problem where they do not work, but my running lights do work, any opinions on what could be causing this I replaced my fuses bad or not. Checked a few wires and clean trailer side 7 pin connector
You didn't say what the tow vehicle is. It's possible, you have more than one fuse box, and you may have replaced the fuses for the truck lights.
My F250 has two fuse boxes, one in cab and one under the hood. My trailering fuses are in the box under the hood, and there are separate fuses for brake / turn (left side, right side) and running lights.
I would suspect (in this order):
1. Burned out bulb
2. Corrosion in the bulb socket (you'll see this on step one)
3. Blown fuse (truck side)
4. Bad ground connection (trailer side)
5. Broken wire (trailer side)
6. Broken wire (truck side)
Most likely, you'll have it working before you get to step four. Please, let us know what you find.
