Vacum Problem
I have no vacum to the dash control for my 2000 Astro Van. The AC works great but I cannot get the varies vent to work as desired. I cannot find where the vacum to the dash AC control originates from. This van is a nightmare to find anything even though I opened up the dash and engine compartment. I need help! Thank You.

Open the hood....remove the intake tube and aircleaner.
On the passenger side is a black plastic tube, running along the "Heater box" and crossing over to the intake manifold...The Heat from the exhaust manifolds wreak havoc , and they usually break apart halfway between the heater box and right side valve cover....Look carefully, you will find the break.....

The tube you are looking for is 1/8 inch hard plastic tubing. if I recall, it goes to a vacuum nipple on the passenger side of the intake chamber, just behind the throttle body.
If you are really brave, and you smoke.......Take the "VAC-PAK" off of the control panel, and blow smoke into it......Have an assistant watch under the hood. where the smoke comes out is where the leak is...
