NOTE:
A leak in the vacuum control circuit may occur during acceleration (slow leak), may exist at all times (large leak) or may exist only when specific functions are selected (indicating a leak in that portion of the circuit). The vacuum hoses used in the passenger compartment control circuit are constructed from PVC plastic material. The vacuum hoses used in the engine compartment are constructed of Hytrel®. Because of the materials used, never pinch off the vacuum hoses to locate a leak during diagnosis. A golf tee can be used as a plug when it is necessary to plug one end of the vacuum hose for leak test purposes.
