Review: Saved me for a cheap price. And saved money by not having to get a mechanic. - Lifesaver for me. My car suddenly totally quit on me and left me stranded. Had it towed home until I could decide what to do. Saw another guy who had the same problem and he said this fixed his problem. My car would not start at all, no click, no nothing. Bought this fuse and installed it myself. Car started right up. Couldn't believe I fixed it my self for such a cheap part and didn't have to have it towed to the shop.
