My 2001 Honda CRV is blowing cold air in the front seat, but in the middle of the summer in the back seat, it's not very cool. If the A/C Clutch isn't engaging, will the A/C still blow somewhat cold? I don't hear it clicking on (unable to visually see it). I'd have to recheck the refrigerant levels too.
No. It wont cool without the clutch engaged. That is how it pumps and therefore cools the refrigerant. (someone correct me if I'm wrong) -- If you can see the belt on your engine, you should be able to see the clutch. You can tell if its engaged by looking at the disk inside the A/C compressor pully. If it rotates, its engaged.
