[QUOTE="machoheadgames, post: 440100, member: 18789"] This makes more sense. I wanted to suggest verifying the 4x4 was working yesterday. When you pull the 4 hole vacuum hose off of the vacuum switch (the 4 prong piece), do you feel suction from any of the 4 holes in the hose when you have the engine running? You should. If not, then you might not be hooked up to the intake manifold vacuum nipple properly. If you do have a problem with the switch, you can buy a new Mopar switch for about $70 which is better quality/reliability than parts store parts. [/QUOTE]
