Hello all.

Hello everyone thanks for the add. Need help with my 2020 explorer I tow a bass boat and recently got a "trailer left turn lamp fault" notification. The dealships won't help and I can't find the fuse in the car manual that specific mentions trailer left turn lamp. I re did all the wiring. And only the right side works. Any ideas would be greatly appreciated. Thanks in advance.

Did you check the bulb and wiring on the trailer?

It’s detecting something from the trailer, it’s not the car.

Welcome to the Forum, John.
As mentioned above, it seems there is an issue with the trailer setup. That is likely why the dealership refused to assist.
Does the left brake light and running light work?
