Helllo, recently my CHMSL/BKUP fuse started blowing constantly in my 04 grand prix gtp comp g. Everytime i replace it, it blows as soon as the car is turned onto the on position. I hear a horrible buzzing sound coming through my car speakers for a few seconds and then it goes silent. Also, when the car is in the ACC position, it causes a buzzing in my stereo, although not nearly as bad as when its turned to the on position. I have an aftermarket cd player and the gmos-04 unit to make it work if that means anything, although it was working fine since i had that up until; recently. If anybody could give me there input on this problem it would be greatly appreciated. I only have three more 15 amp fuses left so i would like to solve the problem before i blow anymore :th_winking: Thanks.
