On my cluster, the LED lights under the switches are wired to the switch itself; that is to say there is no corresponding circuit to the blower to control on/off of the LED. When the switch is on, the LED light goes on, even if the blower is not connected. In fact, I had a spare switch on my helm that did nothing but turn it's LED on/off.
This is consistant with my boat

I'm wondering if the switch/LED combination is not missing either the power or ground connection, thus preventing the LED from turning on with the switch. Note that this power and ground are entirely separate from the blower circuit.
Dumb question...is the ground a black and yellow wire that leads to the wire harness or am I way off here?

If you crawl under the helm with a flashlight and look at the back of the switches, you'll see how they are daisy chained. Look for wiring that is missing/different from it's neighbors. If the wiring all looks good, it's either a bad spade connector, or a bad switch, as you know the LED is ok.
I did not consider a bad switch

Checking for 12V of power from the power and ground supplies to the switch (again, not the wiring for the blower - you can ignore those two wires completely as the blower goes on/off), if you get 12V, you've got a bad switch, if you don't - switch to continuity tests among members of the each chain separately to test the respective connectors to isolate which is 'bad'. (Might not be a bad idea to disconnect the battery for this last test).
I checked the spade connector on the switch and it is "hot." So am I to assume a bad ground or a bad switch?
