cjm1971 - Sounds like there might of been some wires that got fried. There is probably some shorting going on causing you to blow the fuse each time it opens the circuit....You would need to go through and check the resistance of each wire pertaining to the problem. Very time consuming. As mentioned above I would get your truck to a qualified shop for repair. Before you do though, I would go through a file a formal complaint with the auto parts store management and corporate office. Get EVERYTHING in writing!! If it was just a fuse, no big deal but since you can't keep a fuse the problem is obviously a melted wire, etc...Good luck with that!!
