HELP - Tail Lights Grounding Issue
2020 F150 XLT:
Posted in another thread but looking for some more help here. I have no running lights, blinkers, brake lights or reverse lights working. No codes in FORscan, and I checked with a volt meter at the bulbs and I'm definitely getting power, so figure it has to be a grounding issue somewhere. I have no idea where to start looking for the faulty ground, so if anyone has any experience with this, or ideas for a temporary solution, it'd be much appreciated. I have installed a hitch receiver and 7 pin trailer harness for towing (6 months ago), so I originally thought this is where the issue was coming from, but since I'm getting power at the tail lights I don't think this is the case.
Any help is much appreciated.
