Got a 2007 chevrolet cobalt that had the AC stop working but car was still running! Took it to get AC checked and car has not run since. At a Chevrolet dealer now but they have no clue. They seem to guess its the complete fuse box

Hello,

There is a power distribution relay under the hood in the junction box. If that relay is faulty you could have issue like no start or no power.
Check that relay. Inspect it for corrosion or burnt pin.
You can also test the relay as well.
Here is a guide on how to test the relay:

Please let me know of any questions.

Thank you.
