Yep. When it happened to me de-icer spray did not unjam it. Tried a blow torch but didn't want to melt the plastic knobs. Warming up with a hair dryer solved it but as you say that's not really an option when you don't have access to AC power or a big inverter in the truck.I actually had this happen to me already this winter. I don't know what I would have done it I was on the road. I attempted to use Iceoff, a heat gun, and some prying with no quick remedy. I pulled into a heated garage and they came loose. Wish I had a better on the road solution.
