Hey guys,

My dad and I took out, and replaced the heater core today, omfg, what a job that was..... taking out 80% of the dash. Anyway, while we were taking it apart, we noticed that some wires had been 'cut' not sure if it was a factory error, or not? Or mabey it wa supposed to be like that? Here are the pics:

The wires in the red circles are what I am inquiring about (sorry... the camera is a crappy kodak) But then furhter looking we foudn that the plug that goes into the plenum (heater box) has an extra hole for a 3rd wire, could this be fore the cut wire?
Here is that pic:

Wow...........

I knew they wee vaccum lines, but for some reasoin I just said wires. Gee, am I retarted? I mean, but why are they cut? was that done on purpose? Is it supposed to be like that?

A vaccumm diagram is called for! I don't know if Dr. Rebuild has them for the heat/ac system, but it might be worth a look-see. The fact. service manual is good, too, as well as the assembly manual.
I have repaired broken plastic vac. lines like these with short peices of rubber line, as well as heat-shrink tubbing(?). But....you have to know where it goes in the end!

If you look closely, you can see a color code on each one.  You can get small vacuum line to slip over the plastic tube, and connect the color codes together.  This will repair the damage.

The vacuum lines are what operates the blend and temp doors in the heating and A/C.  They come from the heater control in the center console, and use vacuum from the engine intake manifold.
