Welcome to JA

 

If you have a 5 wire brake system, check your grounds, white wire on trailer

and check the blue wire (brake solenoid)

 

if you apply 12V to blue wire, and you here a clicking, you know it works

 

if you have a 4 wire system and a surge brake, it sounds like you brakes are bad or the surge actuator is going out
