I have the same issue. The problem does not repeat itself when I drop it off at the dealership so they are unable to troubleshoot it.
I have a 2007 Nissan Altima. The issue began in November 2012 (just before the five year warranty ended). I woke up early to go to work, it was cold outside and the heating or A/C would not turn on. There is absolutely no noise or air blowing out of it. I have tried turning the car off and on again but this only works occasionally. After several minutes (two to ten minutes), the A/C and heating unit will start blowing air.
It seemed to happen more often last week when the temperatures were as low as the mid twenties at night.
The dealership changed the blower motor, control head, and recharged the A/C in November 2012.
Now, the warranty is expired and the dealership can not troubleshoot it. I took the car in Friday night and it worked perfect all day Saturday. And of course it acted up for us Sunday morning! It is difficult to get it to the dealership when it is acting up.
Anyone else been able to troubleshoot this issue?
