Has anyone had problems with thier re-circulated air button flashing? I have an 07 Grand Vitara and recently when I put my defrost on my re-circulated air button flashes and eventually stops my defrost from working. I took it to the dealership yesterday and they are saying they can find nothing wrong. It seems to only do this after it has sat for a while. I live in Alaska so its cold up here. It usually stops flashing after the system has warmed up but its not supposed to be doing this. Any thoughts?

I realize this is an old thread.  FYI...this winter I experienced the same problem.  It only happened a couple of times, and seemed to correct itslef when the vehicle warmed up.
