Thanks! I did have a mouse nest underneath the relay fuse box this past winter. I did look for a bare wire in and around the box, and found one, which I repaired, but didn't help. Once the wires leave either the accessory fuse box or the relay fuse box, how can I follow them? They sort of disappear into formidable looking megacables.
