In most cases when this occurs, it's down to the wiring being connected to the wrong spots on the 7 way trailer plug. You'll want to be sure you're using the 3 o'clock and 9 o'clock pins when looking at the back of the plug. I've attached a wiring diagram that shows this in better detail that I would ask you to confirm is how you have this wired.

If this is exactly how you have it wired please let me know and I will be happy to look into this further.
