Seeing that the ground wire "looks connected" isn't good enough.

The clicking indicates a good relay if anything.

If you attach a new wire from the ground stud of the fan motor to clean
bare metal of the body you can test whether the existing ground is doing
its job. It probably isn't. I like to permanently add a new ground wire
from the motor and screwed to the body instead of relying on the weak
spade connection of the stock ground wire.
