I finally had to pull the fuse out and cant carry a big trailer anymore. A while back i was having trouble with my trailer brake module that's built into my 05 f250. With no trailer attached it would light up that the brakes were being used and would flash trailer disconnected. It got to where every time i hit a bump it would come on. then it would come on every 5-10 seconds at random, so bad that I had to pull over find the fuse and pull it out. I need to get this fixed but don't know where to start or where to look. I don't want to take it to a stealership and cant afford the new module. Any ideas?
