When I turn the thermostat down to kick the A/C on all it does is make a clicking noise. The outside fan runs and you can hear the inside unit also but no air is coming from the vents. There is a silver box wired to the inside unit and that is where the clicking is coming from. The stickers on the side of the silver box say coil controls and A/C controls with a whole bunch of numbers. I turned the thermostat off so it doesn't run and ruin something else, hopefully. Does anyone know what this might be? :confused:

Clicking sound and no air, might be fan motor or capacitor.
