2010 Honda CRV AC blowing hot air and it's not the fuse

Unfortunately, there aren't really any inexpensive checks (hoses aren't cheap either). First, see if your system is full of refrigerant. If it is, then it's likely an issue with the compressor itself or the clutch and coil of the compressor. This is a reasonably common issue with CRV's of that vintage. Sadly, it's not terribly cheap to fix if you have to pay for it. I'd advise, though, that Honda extended the warranty for the compressor clutch on this vehicle to 7 years or 100,000 miles whichever comes first. It wouldn't hurt to consult a dealership to see if coverage still applies for this part. If it's out of warranty, you could request goodwill consideration. Of course, you should have the system tested first to determine where the failure has occurred.
