Hey i was just gunna go home tonight when i got in my truck and when i started it my locks made a noise like they were locking and when i tried to press the lock unlock button it didnt do anything, no noise, no unlocking what-so-ever. So i thought it was probably just a fuse and then once i got home the truck was still running while i looked through my manual for the fuse section when i noticed my stereo deck all of the sudden shut off, and so i shut off my truck and started it again and the deck did not turn on, and i am thinking this a fuse too. My question is how come these two fuses blew, and how come they blew basically at the same time?
