Thanks for all. The responses, I have not repaired the. Light yet. Cleaned the plug on trailer and truck and still no worked. If the blinker works on the truck wouldn’t that eliminate the truck. I plan to use some emery paper as my next method to repair the light.
Many newer vehicles use relays and separate fuses to isolate the trailer connection from the vehicles turn signals..
So, it is possible to have the vehicles turn signals work but yet the trailers not if a fuse blows or relay fails.
Compounding things a bit more is recent vehicles have switched over to "smart modules" to handle the trailer lights, these modules are able to detect a load present and turn on or off the output.. These modules are a bit sensitive to shorted trailer wiring and can go into a protect mode and never come back.. The only nice thing about smart modules is they will notify you of a trailer light outage fault.
If you have the lights posted by another member, it may be possible that the glue/caulking is holding them in place. If so cut or remove the caulking and see if they come off..
If all else fails, check with a RV dealer service department to see if they will clue you in on how to remove.
