ok first my radio and clock goes out, then my idle begins to flucuate. then as i was driving my speedo needle begins to fall up and down as i do 60 on the fwy. now my alarm will not arm itself, and my side turn signals do not work? my 7.5 amp fuse keeps blowing everytime i try to replace the back up radio fuse.. anyone kno whats wrong, i belive my original problem of my idle fluctuating is electrical because now everything else isnt working as well... please help!!!
