Re: Vacuum Lines
do the vacuum lines run from the left side of the engine down by the radiator? i believe they may have something to do with the cruise control. i could be wrong but i think cody is talking about the blend door which opens and closes to allow heat into the cab (your temp knob controls it), and that is controlled by your accuator (the box sitting behind your glove box with 5 wires coming out of a connector) but i could be wrong so pictures would be nice.
