View Full Version : Rear Break/turn lights

Right rear brake/turn lights not working.
1. The front directional lights work
2. All of the running lights work except the right rear tail and small side running light
3. Trailer lights work including directional.
4. All bulbs are good.

I know it could be a ground but wouldn't know where to start. Is there a fuse for the right rear side of the RV and where would it be.

First clean the socket. Or maybe first take a 12V tester an see if the power is there. Then check the wires going to the socket and check that the ground is not corroded at the socket or at the light assembly. With all of the road grime that cakes on the underside, corrosion is common.

First check your light bulb. It probably has two filaments and one could be good and the other broken. If they look good take it off and use a tester and see if you have power. Get somebody to press on the brake pedal while you test on the rear with the tester, then turn your running lights and test, and the same with the turn signals.
There are fuses for the tail lights, but if it had blown, you would not have lights on either side.
