AC Questions......

I have a 92 Honda Accord (auto) with 155,000 on it. The AC Blew ICE
cold all the time. Yesterday for the first time this year it was 90
degrees and my AC stoped working all together. I get NOTHING but hot
air. The Compressor still sounds like it is activating though. What
is most likly the problem here? Could it be a just a simple fuse? I
checked under the hood in the fuse box and there are no AC fuses under
there. Under the Dash is a bunch of fuses but I belive the guy that
sold the car to me removed it and forgot to put it back. My Chiltons
manual blows, all it says in there is "don't touch it".I really need
to get this working and it seems the heat isn't gonna let up.

Thanks

It sounds to me like you lost all your Freon.....probably need to to
check the seals on the compressor and get it recharged.

 

If you can confirm that the compressor is running (easy to do, just watch
it while someone turns the a/c on and off) then yeah, I'd guess you lost
your charge. You should be able to check for bubbles in the refrigerant (I
think the site glass is at the union for the dryer/receiver, near the
windshield washer fluid reservoir)

Other possibilities: your compressor isn't working, even though it is
turning, your expansion valve is screwed up, your heater knob broke and you
are mixing in enough heat to defeat the AC.

What trim level/engine do you have?

How can you *see* this? On most A/C systems the pulley is turning all
the time, A/C on or off, and the parts after the A/C clutch are not
visible.

 

On every auto AC system I've ever seen, the clutch is the entire center of
the pulley and stops turning whenever the compressor is not running. Just
the outer ring turns with the belt. When it kicks in, suddenly it all
turns. Its really obvious if you are watching it.
