Integra GS 1991
The A/C has worked well for 14 years but this spring it decided to
retire. I don't agree and would like to have it run one more year.
Usually when I push the AC ON with the blower running, the r.p.m.
goes a bit down, an indication that the clutch as engaged and the
compressor is loading the engine.
Now there is no change if I press the A/C ( the green light on the AC
button comes ON) and the air temperature isn't cold.
I have checked the compressor belt and it looks OK and it is running
but I can't tell if the compressor is also running.
I have 2 questions :
1 Where is the fuse for the compressor's clutch, if there is one ?
2 How can I tell if the compressor is running ?

Thanks for the help

Vlad

<x-posted to rec.autos.makers.honda, so the gurus there will see this>

1) The A/C fuses are: 12, 17, 20, 21, and 24. All of these are in the fuse
box under the driver's kick panel.
2) There IS a clutch relay. If it fails, the clutch will not receive power.

Since most electrical problems in older cars result from bad wiring, bad
grounds, and bad relays, start here:

There are grounds all over the place, and they are common to many
components. If you are not experiencing problems with other electrical
accessories, your grounds are fine.

Also, have you checked your sight glass to make sure you've got sufficient
refrigerant? The sight glass is immediately outboard of the compressor.

Good luck.

Funny, my '91 Integra AC just died as well. I assumed it was out of
coolant. I fear if I fill it up (if they still allow that refrigerant
and it's not illegal &/or exorbitant) it won't last. Happened on my
'83 Accord as well after about the same amount of time. Let us know
what you find out and if you solve the problem. You are riding shotgun
for me....Cheers

A friend of mine, gave up after replacing the compressor 3 times. I
can't remember if it's an Accord or a Prelude.
If the problem is the compressor ... by by Integra.
The clutch is also giving bad vibes.
I can't complain. It has been very reliable. I may get another Acura

My Integra only has 80.000 miles.
I'll let you know what I find.

Regards

Vlad

Not illegal, but definitely exorbitant. IIRC R-12 is running around $50/lb
and your system will need a couple pounds if it is so low that the clutch
isn't engaging at all any more. You can also look into conversion to R-134a.

More's the shame that the manufacturing ban was based on bogus science. The
definitive study that determined stratospheric ozone depletion was caused
mainly by sunlight (the NASA/NOAA "POLARIS" mission in 1997
http://cloud1.arc.nasa.gov/polaris/polaris.ems.html) came too late to stop
the Montreal Protocol.

I converted an old car to R134-a a year or two ago, and the cost was
about $100 more than repair and refill of the R-12 system. I figured
that after the next time that something went kerflooey it lost its
coolant, I'd be ahead of the game. And I was. As I recall, the
receiver/dryer and the fill/bleed connectors were the only parts that
had to be replaced. Maybe some gaskets and seals. Then a flush and a
refill with compressor oil and R-135a. I didn't need to replace the
compressor but that may not be true in all cases. Currently, I think
R-135a is $3 or $4 per pound.

I can still remember having cars w/o a/c. Not gonna fix it! Besides, my
daughter takes this one to college in the Fall. Adversity is a great
learning tool. It's got the moonroof and all. There is the defog issue
however..My Integra has about 135K.
