Started up my 09 this morning and noticed the a/c didn't seem to be blowing. The fan was set on 2. 1 didn't work either, but 3 & 4 worked. I turned the dial to "Off" then 1, 2, and 3 stopped working and only 4 works now!

I was on my way in to work, so there wasn't much I could do to diagnose the problem while driving. I turned everything off a couple times at stop lights and tried all of the different climate control settings (which I didn't think would do anything anyway, but there was much else I could do while driving).

Anyone have any ideas?
