If you haven't already, try replacing the AC blower relay located below the glove box on the passenger side. My 07 SE loves to melt and corrode them every few years and the control module stops working/blowing air. Or for a quick fix, remove the relay and wire brush or sand clean the corrosion off the contacts and pop it back in. I started doing this after my 3rd module a few years ago and it keeps on ticking. Worth a shot and costs zero dollars.
