The left blinker/brake/backup lights no longer work...
The running lights and right blinker/brake lights are good.
I've already checked the obvious:
Bulbs are good. (checked with a Meter)
Truck output is good.
I measured the continuity between ground and the left turn pin on the 7way connector and it shows OPEN.
Next, I measured the continuity where the cable harness is located under the dinette to the 7-way connector and it shows good.
Something has gone wrong between the dinette and the shower.
Gosh I hope they don't have to tear things up to fix it...
Has anyone else experienced this?
