My rear running lights don't work but the brake and turn signal lights do I have a trailer wiring harness and the same thing happens with the trailer lights as well-no running lights but everything else does including reverse lights and emergency 4 ways -head lights are fine

Something is being missed,start with checking the fuse for the brake lights. Then check the brake light switch for power in and out(when depressed).Your ground is intact so no power. If still nothing, remove the lamp in question and test the contacts. good luck. Don't forget to depress brake pedal while probing contacts.

SOURCE: 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.

The directional switch is bad. The wiring has a short it seems in your case
