么查啊？还有可能是什么问题？
搜到的建议：1. turn the key to on
2. get a dmm
3.black lead to ground
4.take the red lead and touch both metal tabs at the top of the fuse's
5.the blown one will read 12 on one side of the fuse and 0 on the other. the fuse can be blown without looking blown
木有万用电表啊，再者都换了新fuse也不管用啊。 |

For local store, try Fry's Electronics and Harbor Freight Tools if there is
store near you.
http://www.harborfreight.com/
Or you can get it at Sears for a bit higher price.
