Let's play a game - diagnose my E46 AC problem

E46 AC blows cold... most of the time.

Sometimes there are issues with fan speed. The auto mode just doesn't boost the fan as high as is needed, so I turn the thermostat from 70 down to low 60's... The fan kicks up and it gets nice and cool.

Yesterday the air being blown wasn't cold. I lost all cooling and it was blowing warm air. I had to ride the rest of the trip windows down.

This morning it's working perfectly again.
