AC Compressor and Cooling Fan won't turn on (low temp limit)

I have a 2014 Smart ForTwo Pure and when I press the AC switch, it is not turning on the compressor nor cooling fan. This problem is not 100% of the time, but a large majority of the time. Just yesterday, the AC switch functioned while going to work, but after work wouldn't activate. Fuses 14 and 20 are good so I'm unsure if there's a weak connection somewhere or some other relay or wiring/switch that I should check. Any suggestions would be appreciated.

Funny you mention. The temp dropped quickly yesterday here from the 50's in the morning to the low 30's by end of day. Shouldn't the defrost still engage the compressor though, regardless of temp?
37 degrees was the ticket!

The temps got up to 40 degrees and sure enough the compressor/fan switched on! Thank you for the info.
