Hello! I am new to the site bu I have used it multiple times for myself and friends during various installs, but I recently ran across a problem that has me stumped. I own an 05 Monte Carlo LS 3.4. The radio quit working a few months back but due to my short drive to work I havent worried about it. Well I am getting tired of not having a radio so I began troubleshooting. I have power coming in to the remote wire at the factory amp, the ground is also in good working order. Then it came time to test the factory power, and nothing! I took a jumper wire and jumped it from my aftermarkewt amplifier in the trunk for my subs and Voila! it worked. This tells me that somehow or another the wire went bad or the fuse blew. When the radio originally ent out it would go in and out for almost a month sometimes it would be really scratchy and then shut off and then come back on. The door chime would some like it was in a bucket of water! I dont know what to do short of hacking up my factory wiring harness and running a wire into my distribution block. Does anyoneknow the location of the fuse so I can check there first? Second does ayone have an idea of the routeing of this wire for the factory amplifier? Thanks for your help in advance.

Does anyone have a source for a wiring diagram to point me in the right direction? Any help and I'd be greatful
The fuse is in the fusebox on the passenger side dash. The factory wires run down the passenger side of the car. There is a factory splice in the wire harness just behind the front seat and the splice converts a single wire into the two that feed the factory amp. I just fixed one of these that corroded and failed. Hope this helps.
Dustimizer is correct. These cars are known for the wiring at the passenger rear door sill plate to corode. Make sure that you cut out all the black copper wire and splice in new wire of the same gauge or lower.

That makes perfect sense, the rubber weatherstripping under the wiper cowl fell off and was letting water flood my pass floorboard and then it would roll to the backseat. I remember the first time it happened, my rear floormat was floating!
