Possibly a relay switch. These are similar to fuses and are found in the fuse area only they are bigger and usually about 1 inch square. Unlike a fuse these are difficult to tell if defective. Need a tester or trial and error replacement. expensive to buy new about $20, cheaper at auto wreckers, only a few bucks each.
