Air conditioning/heating seems to work fine if operated manually (temperature low/high, fan max) , however as soon as "Auto" is pressed the fan stops running and there is no airflow. Clearly the basic cooling/heating components are working.

Any ideas?

After disconnecting the battery for a few minutes, the Climate Control seems to be working normally again. I went out today after the sun had warmed the car up and after a few minutes it was blowing cold at quite a rate.
