2009 Honda CRV AC stopped cooling, even with replaced relay

I have a 2004 with the same problem so I unplugged the fuse for 30 seconds, started the truck waited for a minuet and started the AC and it worked fine.

It happened on my 2005 also. I pulled the 10 Amp HVAC fuse under the hood for a few seconds and the system works again. Thanks for the tip!

Took several attempts, but I started the engine, took the HVAC/ECAS fuse out for 10 to 15 seconds and then reinstalled. Everything went back to normal. This may have started from trying to start the engine with an almost dead battery and not the actual battery replacement. I'm not really sure. It may also be a good idea to turn off the HVAC unit and or pulling the fuse before disconnecting the battery for any reason. Thanks for the input folks!
