The fuse for my roof cab lights and pass side marker lights keeps blowing. For a while now once and a while when I would leave in the am I would have no lights, I would throw in a new fuse and I was good to go. Yesterday it took about 6 tries. Today it took one but now it blew again while driving which it has never done before. Also it seems to happen more the colder it gets. BTW I have Recon led cab and dually fender lights. Is there a relay someplace?

 

Sounds like you have a wire that is grounding out
