Hooked a trailer up to my truck this weekend and now my dome lights and cargo lights won't come on when I open up the doors or roll the thumb switch all the way up. Checked fuses but no luck. Thinking might be a bad relay and I noticed most of the problems posted were the lights staying on not off. You can push the switch for the map lights and they do come on so its not the bulbs. 2006 F250 Super Duty Harley not sure if this matters but I have the smaller consol due to the moon roof. Please help

 

How do you replace the cargo light mine looks like it might be built in idk

 

Remove the 2 screws that hold the stop/cargo lamp aasembly in place.. All 3 bulbs are replaced from the backside..
