Hello, this posting is applicable to 2003 EX model with climate control
but without NAVI.

I just listed number of items from my disappointment list related to climate
control /AC system.

1. Fan power control buttons.
These buttons located diagonally one above the other. They have down arrow
(decrease power) on the upper button and up arrow (increase power) on the
down button. I would assume that this should be the other way around.

2. Internal circulation with Auto ON.

I have noticed that in hot day internal circ light stays for quite long (can
be an hour) if I get in the car when it hot from outside sun and Auto is
ON. Then I found a way to get rid of the circ but keeping AUTO. I increase
room temp above normal, at certain point of temperature circ light goes off,
and then I decrease temp back to normal and circ light does not come up. I
see here either a flaw in the logic or defect in the temp sensor. Otherwise
I would expect circ coming up back again when I decrease below threshold
temp. And still, internal circulation longer than 10 minutes seems to be
abnormal.

3. In A/C ON or OFF mode, I assume that I have full control over the
individual controls of the system. But when I increase/decrease temperature
level I notice that fan speed changes too even if I didn't change fan
settings. My assumption that temp and fan should be totally independent in
this scenario.

4. General lack of information in the display and therefore lack of
control.

When AUTO is on, it's ok to have only temperature levels displayed, because
I realize that fan speed, temperature and modes are dynamically changed
depending on outside conditions and temp settings. But as I turn off AUTO, I
assume that these dynamic values are become fixed, but I have no idea what
they are. No fan or mode display at the moment as well as AC ON or OF
indication.

There is an indirect way to find it out though. As I change any of
mentioned settings, it brings these settings to the display and only after
that they stay. I assume these settings should be on display at any time
when AUTO is off. And this indirect way has another drawback. As you bring
value to the display you change it even if you want only to check it.

I would be interested in listening opinions and experience of others,

P.S. I wonder , if there is such a thing as firmware upgrade for car
computer similar to let say cell phone?
