That typically has the opposite effect. Is he turning it on defrost? That will kick on the ac compressor. Coolant is always flowing through the heater core no matter what position. All you change by moving the heater lever is a blend door behind the dash. If the ac is kicking on it cold be a bad fan clutch, partially clogged radiator, or numerous other cooling system problems
