On 7/20/07. I used my air conditioning. It was working OK but not strong. It has not been all that strong on very hot days since I bought the car at 75,000 mi in March '06, but worked OK with recirculated air.
I next tried to use it on 7/27/07. No cold air, not even cool. I had a mechanic look at it: clutch engaging, hi-low pressure test numbers OK (but mechanic suggests this does not say anything about HOW MUCH refrigerant is in system).
When I turn on AC, the box on lower right makes a hissing noise, a cross between "SSSSHHHH" and "SSSSSSS". When I turn it off, it briefly gets louder, then ceases, although you can still hear fan. This noise may have always been associated with AC, but since there was nothing wrong, I never noticed it.
I looked at linkage from manual slider to box at lower right (is this the blend door?). All linkage seems to be OK.
Mechanic (not dealer, but experienced factory-trained Honda mechanic) suggested trying a purge and recharge as first step - cost about $140.00.
Before I spend the money - is there anything else this could be? Is it not kind of sudden to go in 1 week from reasonably effective cooling to none at all? When there is still 80# pressure on the high side?
Could there be a sudden leak? How would you find it?
