Take and twist each fuse in its place. They can build up oxide that will break the connection.

What Motorhead said! ^ They do oxidize at the point of contacts and eliminate a good circuit. I take mine out about once a year and clean up the contacts on the fuse holder prongs as well as the ends of the fuses with emory cloth then I reinstall them and shoot the entire fuse box with silicon spray lubricant. The silicon lubricant dries, does not conduct electricity, and displaces water/moisture ... kind of like WD40 does. Works great and eliminates this problem. Keeps it all nice and clean too!

Replace fuse #12.

Clean the brass contacts prior to installing the new fuse.

YEP YEP!
I checked the fuses agian, and wiggled them and it worked for around 3 blocks, then it stoped working agian, so i changed the fuse, when i pulled the fuse out the metal was stuck to the contacts, and riped apart... so i cleaned the the contact best i could of the side of the road, and put in a new fuse. all is well now!

thanks
Nik
