Hi Harry ,if switch hard to push and other buttons do not come back out , interlock cams are worn . Not helping you at all. Never ever compressed air . Will blow up actuators. There is a thing called mity vac at Napa to test actuators etc .it makes and reads vacuum . I have not had failures at actuators although seals at rod movement at can exit, can dry out -- some silicon ignition grease on rod might help ( oil might hurt it). Get a mighty vac and 3 feet of hose if you want to test . Slight leak ok on rod side .----- If all are not working ( ? Your case?)first follow main vacuum feed hose off switch to engine
Manifold fitting . Often cracked burned cut or hurt during engine work . Fix that . Also check all hoses are on the actuators. A hose off will prevent vacuum . These are actually pretty good setups.. do not despair.! Instructions to remove switch in FSM. Send it white block we can put in new cams . Pull off vacuum plug straight back do not wiggle . Or pry very evenly . Wiggling breaks off tiny nylon tubes on back . Under 100 if unbroken nipples. Someone might have broken them and hid it by putting plug back on = cause of this . We can fix but a charge per nipple . More than 3 better to find new switch . Can help there too , we rebuild scrap ones ( bad cams , but good nipples) occasionally.

Hope this helps.. is it a ram k ?
