I have just moved my parents into a new place, and my dad is maybe giving up driving. He has a 2010 town & country lx with hvac controls above. (we have a 2010 grand caravan sxt). When I drive his van, the hvac choices (bi level, defrost, etc) do not light up, and is difficult to make a choice at night. Our grand caravan sxt has them illuminated (we also have heated seat buttons on the bottom of the unit). Can anyone confirm that the hvac choices should be illuminated at night on the hvac controls pictured above?
