Heyo,

My 2007 Acura was having intermittent AC issues, Read a low measure on L pressure valve and filled with up with an autozone AC refill bottle. After the refill the AC was not working whatsoever, the engine would sound as if the AC was begin turned on but would blow hot air. I took out the AC RELAY under the hood and parts shook inside upon pulling out as if the relay was already broken. I replaced Relay with another identical relay in the engine and restarted the engine and no fix was had. With the car on and the AC on it does not seem like the clutch is engaging whatsoever.
Question is, what would be next to check to try to isolate the break? and are their any other fuses which could have blown with the blown relay being in the car for a few weeks. tx

 

There’s a lot of info on this main A/C Clutch relay thread:
