2006 Titan LE with big tow. So here's how it all began. I bought the truck and had been towing my Skeeter with it. Everything worked fine until last fall. Fuse #32 blew so I replaced it thinking maybe it's just old. As soon as I replaced it the trailer running lights got dim and dimmer everytime I towed it. It blew fuses frequently so i figured there was a short somewhere. Found a slit cut open on running lamp wire with corrosion near the 7 pin connector. Repaired that and changed the fuse and have no running lights now. Ive checked the tow relays and they all click once i add power to them. Tried chasing wires with power probe but couldnt find any shorts or broken wires. Ive been searching all day and now im stuck.
