I recently pulled my 2007 Western Star out of its regular servicing. (Just oil change etc...). The weather had been about minus 40, and had a chance to thaw out during the servicing.
Upon getting into my truck, I noticed that my diff lock light was on.
But it appears to disengage and engage when I need to. No signs of scrubbing on my tires - at least what I can make out.
Im thinking its a sensor. Or electrical. I checked my airlines, even dumped the air in my trailers to see if there was moisture. Nope. Nothing.
Im going to be dropping my trailers to see if I can get into a tire shop so they can lift the back end of my truck to make sure that they are disengaged.
Any other suggestions?

My guess would be moisture in the pressure switch that activates the light, refroze when you pulled it out of the shop... Or the switch had ice in it and thawed, damaging the switch.
I'd recommend moving to southern Florida until the truck defrosts.
