Programmer Removal & Installation: Removal

Disconnect battery cable, remove glove box (all models except Oldsmobile) and cold air duct (Chevrolet & Pontiac only). On Oldsmobile models, disconnect aspirator hose. On all models, disconnect electrical connector plug and vacuum harness from vacuum valve, loosen adjustment screw and disengage link assembly from programmer output shaft. Take out three mounting screws from programmer case, then pull programmer straight off blower housing (to avoid damage to resistor assembly on back of case) and lift programmer out. Remove cover for component replacement.
