Since I bought my "07 Camry, when I push the recirc button to prevent
outside air from flowing into the cabin, it will go off after awhile
and outside air starts to come through. I took it in while it was
under warranty but the first time they told me they didn't have anyone
at the Toyota agency that day who could work on electronics. I took
it back again and they couldn't figure out the source of the problem.
It's an intermittent problem so I understand the difficulty for them
to track it down, but since they couldn't figure it out, I was
surprised they didn't offer to replace the unit since the car was
under warranty. My own fault for not pushing it. I just took the car
in to have a couple recall items fixed and asked that they try again,
but they couldn't identify the source of the problem. Instead, they
recommend I go on a road test with them. But the problem may not
occur for 25, or 50 or who knows how many miles. And even if it did,
what would that tell them? I think they just need confirmation it
really does occur. I can understand that they may not just simply
trust my word so I'm wondering if anyone else out there has the same
problem. Perhaps it goes on far more often than anyone knows,
although if that was the case I would assume they would have had the
answer and a solution in my case.

How are the vents directed while you're waiting to see if recirculate
changes its setting? Any chance you're cycling the control through the
defrost position? I'm asking because in my 04 Tacoma, recirculate is
DEactivated when I switch to defrost. I can REactivate it once the control
is on defrost, but the default is for the car to DEactivate that feature
because it's a good idea.

The workings of the Recirc function is one that confuses the hell out of me.
I have an 08 Avalon and for a while thought that the Recirc system had a
mind of it's own. One of the things that I finally figured out (at least in
my car) was that it is tied to the outside air temp and the temp setting of
the heating/AC system. Try this experiment--vary the heat temperature
setting and watch the Recirc light--at some point it will go from Off to On
and visa versa as you move the setting up and down.
Let us know how it works out.

I rarely use the defrost setting since I live in Southern California.
However, there are those cold days when I do. As I recall, it's not
always a partciularly cold day that this occurs, but I can't be
certain. Maybe I start out on a cold morning and leave it in the
defrost position. However, that's rare. I usually run it for only a
minute or two with the heat turned up to the max just to defrost the
windows and turn it back to having the vents flowing from the floor or
floor/dash. But I'll keep this in mind and I'll be more aware in the
future what the settings are at the time this occurs or even what the
settings may have been earlier in that particular drive. I'll also
try leaving it in the defrost mode next time I drive to see what
happens.
Thanks.

I wasn't aware the temp control alone would affect the recirc setting.
I'll give that a try. I do adjust the control at times, but the
problem occurs even after I haven't touched any part of the A/C for
awhile. But I'll try the experiment in case I have the temp control
right at point where it might be close the trigger point as you
mention. If that's the case, maybe it's simply the vibration or a
bump in the road that sets it off.
Thanks.
