The single flash on the LED is telling you there is a “low air flow” condition.

If the fan doesn’t spin up the sail switch will not do anything. You need to read the service manual and test the fan blower motor first.. it has its own DC wire leads to it and when commanded ON via thermostat and air conditioner control module or gateway fan should spin up if 12 volts DC is present at leads to fan

Good,luck with your endeavors
