Cruise Control Servo: Testing and Inspection

1.

Disconnect vacuum hose from servo and apply approximately 14 inches of vacuum to servo using a suitable pump with an integral gauge.

2.

If servo loses more than 5 inches of vacuum in 1 minute, servo is defective. Connecting vacuum hoses can be checked using a similar test
procedure.
