That kit sounds interesting. My 25A fuse for the AC can get warm on HIGH speed to I just run it on AUTO to the fan only goes up the speed 4 instead of speed 5. This seems to really help but the kit sounds slick but not too interested in crawling under the dash, but I would if need be. Question: My 25A has never blown but it gets, I wonder if the Porcelain Fuses are any good? I see Phils sell them but you have to get 20 for like $5 for all 20. Anybody use the 25A blue fuses in this slot, or is the External Kit the way to go?

Are there directions Ks? Glad you posted!
