I am having problems with my brake controller in my 2006 GMC. The green light turns on and the brakes work when I manually turn them on with the controller itself and the green light turns red indicating that it is working. When I use my brake pedal I can not get my trailer brakes to work and the light stays green. Any idea what this might be?

Which controller do you have? Check to see if your third brakelight is working. Might have blown a fuse.

Kinda hard to help when we don't know what controller you have

This fuse is in the left hand dashboard fuse panel.

Thanks for the replies. It ended up just being a loose connection.
