Based on what you are saying I would look to see if there are any corroded or broken wires, and I would take a good look at the ground wires that are leading into each of your rear lites.
Sometimes a wire will look as though it is connected but in fact has corroded off inside of the connector.
If the trailer plug is an afterthought then I would carefully inspect each of the wires as some people use test lites that have to be poked through the insulation on the wire thus allowing condensation to get into the wire and corrode them.
At each point where two wires meet and where ever a wire go's into a connector or lite socket ( pigtail ) I would give the wire a little tug to see that it indeed is secure.
Also if you have a test lite then remove the lite bulbs and test to see if there is any power to the lite pigtail itself. I'm sure that you have physically checked each bulb itself. if notthis is rare but it does happen on occasions, a bulb will burn out and the filament in the bulb will drop down and across to the other filament on the bulb causing the lite to short out that particular circuit and this will only happen when that particular part of the circuit is powered. As I mentioned this is very rare I've only seen it happen twice in my career.
Good luck, and I hope that this info is helpfull.

2001 2500hd silverado no stop lights at trailer connection (7 pin) turn signals work fine and no problems with truck itself (fuses are ok and the brake pedal switch is operating ok


How have you tested this? If you are just looking for the stop or brake light, you need to test by pressing the break and probing the same pin as the turn signals as the vehicle does not have separate brake and turn signals. However, If the problem is that you have no signal for the electric brakes on your trailer. You must have a brake controller installed. If there is one installed probe the blue wire coming out the back end of it and press the brake to be sure there is brake output. It is possible for a controller to go bad, and not output anymore.

Check at the light socket in the rear, where your lights don't work. You need a test light or a voltage meter, and check to see that you have a groun there, power for your parking light, and power to the brake light. You should have power for the parking lights seeing that it works, and a ground. Just verify that your power for the brakes is getting to the bulb, or not. Just a good place to start.
And you are correct that if the third brake light works (top) your brake light switch is fine.

Tail lights not on no signals rear


If you have an aftermarket trailer plug on it, remove it, or unhook the wires. They are shorting out. If you don't have a trailer plug, then check the wires at the back of your truck. They must be pounded from stones,and are shorting out.

I have no power for right brake light in main trailer wiring harness. Right turn signal works fine


Brake lights are not seperated but are tied into the turn signal control. If the turn signal on that side doesn't work,but does on the other sidem chk connections on tail light assembly. No offence but check the bulb If all is fine then chkthe turn signsl control by working it. No power? was this ascertained by the bulb not lighting or by using a test light? Just a need to know question, no offence intended.
