Yo so my truck is being weird. I have a 2015 Ford f150 king ranch and with the king ranch you get box lightning and mirror lights and my box lights turn on randomly after 8 mins and they pulse and I don't want to drain my battery out can I fix this? Thank you.

 

Have you checked the switch located inside the box? Sounds like it needs to be replaced. Either that or the interior switch.

 

where is the switch located inside the box? Thanks

 

Below the light on the drivers side.
I'm not really thrilled with the masking job LINE-X did on the switch.

Those early switches were not well made. I had to replace mine. The replacement had a much better feel to it and I'm guessing they changed the design. They are fairly inexpensive and easy to change. The same switch is used on many other SUV vehicles with power tailgates. Motorcraft SW-7544 (FL3Z-9C888-B).
