Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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.
