Honda Car Forum

I am posing this question here, as well as at Odyclub, since it may
apply to more than Odysseys, and some Odyssey owners may not go there.

The A/X in my wife's 2001 Odyssey EX occasionally stops cooling. The
fan continues to blow, nothing else is noticably different - it is still
a drag on the motor, and so forth. But the air coming out of the vents
will get warmer, just as if I left the fan on and turned the compressor
off. Sometimes it will start blowing cool/cold air again quickly.
Sometimes it will not blow cold again for quite a while (forty-five
minutes yesterday on the Interstate). The Honda dealership will only
check it when I bring it to them. Since I have not been able to get it
to them *while* it was malfunctioning, they won't attempt to diagnose
it, much less resolve it.

Any ideas? I have done some searching, and although I have seen the A/C
as a topic in some discussions, I have not seen this kind of
intermittent cooling as a topic.

Thanks.

Maybe it's just icing up inside? Have you ever changed the cabin filter,
and are you using 'recirc' to reduce load / icing? If it's really humid
outside, and you fail to use 'recirc', you're trying to dehumidify the
great outdoors, which could ice the core very quickly. What does your
owner's manual say?

I had this exact problem with a 2000 Odyssey. Eventually it
was cured when Honda had a recall to replace some sort
of multiplexer device because of some other problem they
said. Anyway, it fixed the A/C problem also.

I have changed the cabin (dust & pollen) filter at 30K miles and at 60K
miles, as outlined in my manual. I haven't looked at it, and it may in
fact have become obscured in the 15K miles since then, although I doubt
it. I will look, though.

As for using recirc, it does come on from time to time, but is never set
manually. The system is set on 70 degrees fahrenheit, full auto. This
is designed to heat or cool as needed based on temperature at its
sensors. So far as I know, manual intervention is not required.
Although I haven't checked specifically for reference to this, I don't
believe the owner's manual addresses the problem. I feel certain that
it is not an ordinary occurrence. I will look for this as well, however.

Thanks, Curls.

Thanks, Dick; I'll keep this in mind. I think that my car *did*
participate in that recall, some time ago; it had something to do with a
dashboard power failure, as I recall.
