need to check the wiring for any signs of damage. if nothing obvious get a test light or a multi meter and start checking the wires.


Wiring not the issue,just tried my other trailer same thing


then there is something wrong with the wiring on the vehicle. check the trailer connector see if you have signal to that point.

Best Answer

Right under the back of the truck by tailgate is where that pigtail ties into the electrical system of your truck. Between bumper and rear axle. Sometimes that connector can become loose.


Have signal at plug on tk left turn bright,rt turn weak. Signal rt turn&break on trailer work with test light but does not work when bulb installed ( new bulbs)


Make sure light assembly has a good ground to trailer. Also make sure white wire from trailer pig tail is grounded to the frame of the trailer. Either of these two issues will cause the kind of problem you are having.
