Everyone wants an answer but does not want to look........

I am planning to change the filters, regardless of the cause of the problem because I’m sure they could use the change. I just have a feeling that the underlying cause of the problem might not be the filters, since the issue seemed to show up suddenly. It is possible that I just didn’t notice a more or less gradual loss of flow, with not really needing heat until recently, but it just seemed like a sudden acute failure of some kind. I will definitely check the filters and anything else that is accessible from the wiper side of the system. For example, it will give me a chance to change the squeaky fan motor, or at least get some lube on the thing.

Bye the way, do you think the re-circulation switch bypasses the filters? It seems that it could, since the engineers may have figured you wouldn’t need to filter the air that is already in the car.
