    Vehicle: 2002 Buick Century Limited 3.1 V6 GAS

    While a detailed diagnostic procedure for all air conditioning systems would be impractical due to the many variations in construction and operation, there are three fundamental components of a total diagnosis:

    • Refrigerant systems must have an adequate, but not excessive charge.
    • Determination must be made whether the refrigerant system is governed by a cycling clutch compressor or by valves which control evaporator pressure.
    • The air distribution system (blower motor, switches, vacuum lines and air ducts) must be operational before checking the ...

    System Operation

    Anti-Lock Brake System (ABS)

    The ABS system will control hydraulic pressure in the individual wheel circuits to prevent any wheel from slipping. A separate hydraulic line and specific solenoid valves are provided for each wheel. The ABS can decrease, hold or increase hydraulic pressure to each wheel brake. However, it cannot increase hydraulic pressure above what the master cylinder is transmitting.

    Enhanced Traction System (ETS)

    The ETS limits wheel slip during acceleration when one or more of the drive wheels are accelerating too rapidly and the brake switch is off. T...
