Famous 2002 Honda Civic Check Engine Light No Power 2023. I had 3 mechanics look at it, the a/c worked fine for about 2 days, then back to blowing. It could be an issue with the bcm/micu, but it's probably something more simple.

Blown ignition switch fuse there’s a fuse in the battery compartment of your car which is called the ignition switch fuse. If you don’t notice any performance issues and check engine light is not flashing, tighten the gas cap and continue driving. This is a silly thing to go to the mechanic over, so make sure you check it first.
