The fuse would be the first place I would look for the problem.

Not at home now but I will pull the schematics and we'll start diagnostics.
Do you know how to use a voltmeter and ohmmeter because their use will be needed. A multimeter can do both.
How do you know the fuses are fine. Did you pull and test for continuity or measure voltage on each side when installed? Looking is not the way unless you see it blown.

Great, here is the schematic and connector views. Radio connector C1 has power feeding in on pin 10 and ground on pin 5.

Just make sure you are looking at Fuse 5 in the passenger foot well. Had one guy make that mistake and was looking in the engine box.
If you need to test from the fuse box connector to the radio I can post that connector also.
Let me know if I can provide anything else.
Should not be hard to find the issue, let me know what you find and we'll go from there.

2000 c5 convertible radio no power.
I hv a 2000 c5 convertible and I changed out the factory radio for an aftermarket one and tested it out it worked fine so I proceeded to finish up the install and tested it again, now it's not powering up so I connected factory radio back up and it now has no power as well. Are the schematics for the 99 the same for the 2000?

I know this is a 6 year old thread but Music707's problem is the same

2000 c5 convertible radio no power.
Yes it was the fuse thnx a lot I really appreciate the information. And so far I've updated the radio with backup camera and I was able to keep bose speaker system utilizing the pac wiring harness kit and added an additional amp and sub. Upgraded headlights and fog lights to leds (much brighter) and added a cold air intake and borla exhaust axle back but didn't run into any issues until I messed with the radio. Thnx again for the help
