If you pull the surround trim from the fan, you can likely find the wires that feed it. Look for where the wires are tied and make sure they are connected, most crimp connectors or wire nuts can be probed with a meter to check voltage.

You sir are surely getting a quality service!


Absolutely...I am fortunate to live and camp, with a Domestic Engineer!

To the OP...did you get your fan going?

There are a few parts that are suspect
First is there 12 volts to the fan assembly (Use a test light not a volt meter please) (Bright is good, Dim is not)

The 4 position switch (OFF LOW MED HIGH)
The Thermostat
The Lid Switch

You can bypass the lid switch and the T-Stat to test.

Not sure how the 4-pos is wired. so not sure how to bypass.
Home was where I park it. but alas the.
2005 Damon Intruder 377 Alas declared a total loss
after a semi "nicked" it. Still have the radios

The switch is just a plunger and you can try tugging on the plunger to see if the fan comes on. When the cover closes it pushes the plunger down which disables the power to the fan. The plunger switch tends to get corroded or stuck with gunk, especially when camped near the seashore. If it is the plunger, a little WD-40 will clean it up and solve the problems.
