01 9400 power divider light not coming on

Pulling into a snowy parking lot today, I flipped my power divider switch (while coasting), but the light did not illuminate. Is the light just a visual confirmation that the switch has been flipped, or does it actually confirm the power divider is locked?

I didn't spin or anything and don't know whether it was actually working.


What are the trouble-shooting steps? Could this be related to the earlier flash code for a shorted auxiliary?

 

I hear air the typical air sounds when I flip the switch, but based on performance today I'm 99% sure the power divider itself is not engaging.

Any ideas @Heavyd ?

 

Update:
Power divider is engaging. There are no wires at all going to the power divider. Bulb is good. f4-a good.

New info:
None of the other lights in that vertical warning cluster, except ABS, are working. Dunno why ABS works and the others dont... Other lights include suspension dump, 5th wheel unlock, coolant temp, low fuel level, etc

 

There are, and for ####s & giggles I tested the switch & it (the electronic portion) is bad.

Thanks again.


Do the warning lights on that panel not light when you first turn the key on? I'm thinking ABS might be the only light that gets illuminated/tested at start-up...
