Shutter Valve Actuators

WARNING: This page is about a different car, the 1995 Mazda Millenia. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect vacuum hose from shutter valve actuators No. 1 and 2. See Fig 1 . Connect vacuum pump to actuator. Apply vacuum to each actuator separately and verify shutter valve rod retracts. Ensure both shutter valves move freely. Replace actuator as necessary.
