The lid will not go up unless the fan switch is on and power going through, so that rules out the 3 position switch being bad.
The rain sensor will prevent the lid from raising if it is shorted, so the rain sensor is good.
There is a plunger switch that the lid pressed down to turn the fan off as the lid loses. That switch might need lubrication or it could be bad. Turn the power switch to off and/or remove the fuse. Raise the lid manually. Remove the screen. I can reach (long fingers) through the fan and check to see if the plunger is extended. If not extended with the lid open, that's the problem. If it is extended, the switch could be bad. Check for continuity with the plunger extended.
If it is not the plunger switch, remove the trim and the fan body shroud, looking for loose wires.
If not the above:
Fan motor could be bad.
Circuit board could be bad.
Thermostat could be bad.
In prior times I would have suggested calling Fantastic customer service. Last couple of times I did the people I talked to knew less than I did about their product.
