2014 F-250 trailer tail/parking lights used to work, now after taking it to the dealer for repair under warranty, I am being told that they only work when the tow/haul button is pressed with the ignition on. This doesn't make sense to me, the parking lights would only work on the truck then.... I think the dealer is feeding me a line...
The lights used to work, and they are tlling me that I am wrong....
