- If vacuum servo does not move and hold, remove vacuum hoses from servo. Plug or cap one port on servo. Connect vacuum test pump to other port on servo. Apply a 10 in. Hg steady vacuum and confirm servo moves and holds.
- Switch vacuum test pump and plug to test other side of servo. If either side fails to move and hold position, replace servo.
- Disconnect vacuum hoses from load control solenoids. Connect test hose to port "A" and confirm air exits from port "C". Apply battery voltage to Black/White terminal of solenoid and ground Blue/Yellow terminal on A/C load control solenoid and Light Green/Red terminal of electrical load control solenoid. Blow into port "A" and confirm air exits from port "B". If not correct, replace solenoid(s).
