If they both do not come on when you turn on the A/C there could be several reasons. If you suspect the fan is bad, disconnect the plug in to the fan and run wires from your battery direct to
Simply put, there is a direct correlation between the air temperature and the rate the water will evaporate. Temperatures over 110 will lead to small water droplets evaporating in under a second. If the temperature is in the 80s, misting fans loose so much of their cooling ability they normally aren’t even used. pXeKq.
