Help trailer brake lights and turn signals not working

I have an 06 silverado 2500 and all the lights on the vehicle are working. When I hook up my boat trailer the running lights work but not the turn signals or brake lights. I checked the fuses and they appear fine. The trailer wiring is all new and works fine when hooked to another truck. Any suggestions?

Those fuses can be tricky....I keep a pack of 20 amp fuses for this very issue. Make sure you are checking the right fuses.
If you are using an adaptor to change from the 7 pin plug to a 4 pin plug, check that out

The trailer fuses are located in the panel on the driver side end of the dash, they are different from the truck tai/brakel light fuses.

IMO I always start with the ground with anything electrical. A bad ground can cause so many weird problems.

Of course I forgot to say after checking the fuses like those above me said.

Is the trailer light connection on the back of the truck live from the factory or do you have to do something to activate it?

Yes all lights are alive from the factory.

The 12 volt power at the plug may not be hot on some vehicles, but that is usually caused by GM using a dummy fuse and not a real fuse.

I am having the same problem. My right brake/turnsignal on the trailer isn't working. The left is working just fine. I checked and replaced the fuse under the panel inside the driver side door and it still is not working. Any help would be a great appreciated. Sorry about hijacking the thread but it seems we are having a similar issue.

I'm not sure if I'm going to give you a correct answer here but I owned a 2004 Chevy 2500hd and there is another fuse block under the hood left side near the brake fluid there I used to blow those fuses alot but all it takes is a little moisture try using a little connector grease from an auto store. Hope this helps
