The crossword solution for the term 'DASH CONTROL' is 'DEFOG', which stands for 'defogger'. A defogger is a device that helps to reduce or eliminate fogging on the inside of a vehicle's windshield. It works by using a fan to blow warm air onto the windshield, which helps to evaporate the moisture that causes fogging.
