I have a 2011 Silverado and my trailer lights all work except for the right brake and turn signal. I have replaced the trailer lights and check all the wiring. It seem that I not getting the source from the truck for the right brake and turn signal. Does anyone have a suggestion.

 

to clarify: the lights on the truck work but your right trailer lights are inop? How did you check all the wiring? Where did you check for power to the light and how did you test for it...dvom, test light?


check for power at the 7pin connector. the cover is labelled for which pin to test.
if you have power there, check for power at the right bulb. If power is there, provide a redundant grd for the bulb.


does the trailer have Leds lights or bulbs?

 

Just the right turn signal and brake light do not work, the running light is fine. The lights are LED. I checked with a volt meter and I cannot find the power at the truck. Don't know where to go from there

 

Thanks for your input......I finally realized that it had blown a fuse under the hood.
