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.
