When we first got our Hi-Lo, we thought our refrigerator fan didn't work. Others here on HTF explained to us that this fan has a thermostat, and even when the switch is turned on, the fan won't run unless the thermostat kicks it in. Happily we discovered that our fan worked fine.
You may already know this, but it doesn't hurt to make sure. Since you have already checked the fuses, I tried to find a good wiring diagram for the fan circuit, so that you could test the circuit. The best one I found, and it’s not very good, is from Dometic. It's here in our library, here's the link...

I think your next step is to use an electrical tester and check each point of the fan circuit to see where the failure is.
