Everyone should own a DVM just for these problems Pete.
First, you have to determine if you have power in the circuit. Use DVM to test.
If you have power, then check the ground at the fan motor. Many times the problem is with a poor ground.
The other thing to check on the Fantastic Fans is the switch that activates the fan when the lid is opened. The little button on this switch sometimes sticks and needs a spray of silicone to free up.
As stated above, looking at a fuse many times will give you the wrong message. Test it with a DVM and this will tell you where to look next to solve your problem.
I sure like the White Lake area Pete. Are you doing any ice fishing this week?
