HVAC control unit vacuum
Hello everyone,
While my dash is off on my 71 442 I decided to check the vacuum controls on my duct system. All of the actuators hold a vacuum and operate normally. However, when I put vacuum onto the control unit from the source after the vacuum reservoir, it bleeds off within a couple seconds. Is this normal?
Thank you,
Steve
