Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
The radio has power, with an alternative power source but no sound. Stock radio wire has no power. Looking on the front of the radio, you can change stations and make the volume go up and down, this is a stock stereo. The radio, the power amp (in the trunk), the rear window defroster and the heated mirrors are on the same power source from under the hood. The heated mirrors work but nothing else does. The radio fuse is good, but not getting power from fuse box under the hood. 30amp defroster breaker has continuity. Defroster relay has continuity. All other fuses in all fuse boxes have been tested and are good. Also the horn does not work, no fuse in any boxes labeled for horn. Thanks for your help!!!!!
There is a single wire from that 60 amp fuse to the feed the rear window and radio fuse bus bar in the fuse block.
