I am Pete, and I'll be happy to assist with your question.

If the fan is working ok on slow speed, then the fan motor is functional and the fuse is good, so the problem must lie with the speed selection switch.
Try rocking the switch between the settings and see if that gets it working again. Sometimes grease can built up on the switch contacts over time and stop the switch from working correctly. Wiggling it around between the settings can help it make good contact again.
If that still does not work, then the switch will need to be replaced.
