I have a 97 Civic EX that recently had to have the battery
replaced. Since the battery was replaced, it has been
necessary to turn the AC on every time the engine is
started. Beforehand, the AC would retain its setting
between starts.

I know this isn't a big issue, but it would be nice if
I could figure out exactly why it's doing this. Also,
the thought crossed my mind that other electrical
components might be affected that I have not noticed
yet.

Does anyone have any ideas or pointers as to where I
could try to find information on this?

Thanks in advance.

the a/c switch & battery are unrelated issues. timing may be
coincident, but it's a fluke. and your a/c switch is a "soft" switch,
ie. the power needs to be active for it to stay on. once power is off,
it switches off & stays off until ignition restart, so the operation
your noticing as "wrong" is actually correct.

That is highly unusual. I did not actually drive the car much over
Christmas, and I just assumed the two were somehow related. I was
almost certain that the AC used to stay set. Now, I'm kind of worried
that my mind may be going, but thanks for the information.

It sounds like the software 'trick' that causes your driver's window to
go down all the way on a Pilot. If battery power is lost, it has to be
reprogrammed to do that trick. Apparently it's in the Owner's manual.
It's one of those "hold this button, turn on key, turn that knob" kind
of things. Same thing on the CR-V that makes the 'Recirc' come on when
DEfrost is selected . . the 'default' program can be defeated by a few
simple steps . . .

If it's not in your manual, try google.com to find if there's something
like a "civic-tinkerer.com" forum.

Thanks for the information. I'll take a look in the manual
and see what I can find.

If the air vents are set to defrost, the AC will automatically engage after
start-up.
