The problem is that the fan is not working on "high". It works fine on the other speeds.

There is a seperate power supply to the blower relay that provides power for high speed. It will be either an orange or red wire, red I think. This should have power at all time, and the relay switches this directly to the blower. The high speed position on the blower switch turns on the relay.
