I have a 2013 Escape 17B. When I try to 1) check the amount of water in my tanks, 2) turn on the water pump, or 3) turn on the furnace, a little red light comes on in the fuse box. If I touch the fuse next to the red light, Nos. 1, 2 or 3 work sometimes. Should I replace the fuse? What does the little red light mean? Thanks!
