So up until recently my civic coupe has been a real champ and running awesome. Now, its on my driveway dead. I need some help and I am hoping this forum can give me some guidance or at least a direction to start with. Let me lay it out:

1. The AC lately has been having issues, it will blow cold and as your driving it just stops working and blows hot air. But its been intermittent so we've been unable to find the issue. My mechanic drained the freon and refilled it and looked for leaks but there are none. This has been going on for weeks now.
2. The battery seems to drop dead within a few days. So a few days ago I jumped it and it ran for a couple of days and now its died yet again. But in testing after a jump both the alternator and the battery go into the right range. So I know they are working but something is causing a drain.
3. The car has an aftermarket radio due to the original radio breaking a few years ago, so I know that if it was the radio, it would have happened a long time ago.

Any thoughts or help I'd very much appreciate. Or if you have any further questions I might be able to answer to help me get this working correctly, let me know.

Thank you in advance.

Electrical drain can be anywhere in the whole car, someone will need to scour through the wiring and find it... Sorry but no other way

Check the compressor clutch gap. Over time it becomes big enough to cause the compressor clutch to slip. This then overheats the compressor and it will shutoff to prevent damage. To fix, remove the compressor clutch and take out a washer, then reinstall.

You're going to need a multimeter. You then measure the current through every fuse until you find which one has a high draw. That narrows it down to a few things to go check.

Unless the radio is failing...
