I actually have a vacuum diagram for a 97 Chevy Astro. It should be about the same for the 2000 Astro Van. You can actually get it at the dealer. If you go to any Chevy Dealer and go to the Parts Department, they will usually print out any diagram that you need for free. I can send it to you if you give me your email address. So are you having problems with the air blowing out of the defrost?
I appreciate your help & enjoy this holiday weekend.

I wanted to say THANK ~YOU for the very valuable information you had sent me via email to my posting on a vacuum system problem with my 2005 Chevy Astro van yesterday. My boyfriend went up to the corner NAPA Auto Parts store this morning and spent $3.50 on some vacuum line hose. The job took just an hour to fix and now my ac runs perfect. Thank you for helping us save $200+ for such as simple repair. You're an angel. Please stay safe & enjoy the rest of your Labor Day weekend. 0:)

I feel like a bit of an eavesdropper, but I am having an identical problem with my 2001 Chevy Astro van (AC only blows thru defrost and "Max AC" setting blows same as normal "AC" setting). This is after being charged $1600.00 for a new AC system. No, I will never use that mechanic again, I swear.
Do you still have a diagram of the vacuum system? If so, could I beg you to send me a copy?
Thank you,

Very helpful and very appreciated!
I have a 2004 chevy astro with the same problem. The hvac is stuck on distributing air through the defrost. It changes the type of air output (max ac, ac, vent air) but won't move the flaps to change the output direction. If you could e-mail the solution to me that would be great... babcock.tony at gmail.com
Thanks in advance.
On 09/06/2010 I had posted a "trouble w/ my front ac vents on a 2005, Chevy Astro van not allowing the ac to flow out" question. The gentleman that assisted me told me abou a possible HOSE problem! That hose problem was NOT a $200+ mechanic job but marely a $3.50 hose problem that took my boyfriend a a short 1 hour start to finish job. Please check your ac hoses....so simple and so obvious that it totally floored me! Best of luck.

Thanks so much.
Sorry i didn't respond earlier. I got the email notification about your post, but I forgot to get on the forum and message you. Just post an email address and I will email you the Vacuum Diagram and the instructions on how to fix the problem. This problem is a simple one and caused by the plastic vacuum lines breaking apart and so the AC unit doesn't have any vacuum (suction) to push the air through the vents and it just comes out of the defrost.
Just post your email address for me and I will email you the vacuum diagram and the information on how to fix the problem.
I just wanted to post my instructions for the vacuum line repair problem where the air blows out of the Defrost Vents only and not the front vents. It is an annoying problem, but certainly very cheap and easy to fix with a little work and some cheap parts. I also have the vacuum diagram, but I am not sure how to post it on the forum so if you need a copy, just post your email address and I will email you a copy of it.
I have the vacuum Diagram for a 97' Chevy Astro and from what I understand it should be the same for all the upper model astros and I think the GMC Safarri's as well (But I am not sure about the GMCs). If you are having the air come out from the defrost and not from the vents, you should check 3 critical areas. So I will try to explain it to you as best as I can. So if you are standing in front of the Astro and open the hood, you would look to your left hand side first. There is a big black box like thing all the way to the left (and that is the ac blower fan). Right beside that, there is a medium size silver canister that should have tubes coming out from it. That is the AC condenser and that is where you would recharge Freon to the car. Right next to the canister (on the right side, tucked in a little) you should find some sort of a t-connector with three vacuum hoses connected to it, Once should be going into the firewall (the wall of the car going into the vehicle, one should be going down towards the bottom of the car, and the other should be going to the right. Most likely, the one going to the right is the one that is broken. That one passes to the right by the alternator and other things on its way to the engine manifold where it connects in. That area is extremely hot (when the car is on) and that is why those vacuum lines tend to break down quickly (Thank Chevy for their stupid designs, LOL). It may take some bending and moving with your hand to get into those tight spaces to reach the other end of the vacuum hose. They sell replacement vacuum hose/tubing at Napa Auto Parts by the foot, and they have vacuum connector heads in multi-packs at Auto Zone. Basically, you will have to build your own new vacuum tube with a head on each end, one to connect into the t-connector and one to connect on the engine manifold. I would make the tube a bit longer so you can position it away from the hotter parts of the car and you can use plastic strapping ties to secure it so that it doesn't get caught in any gears belts, etc.
That should solve the problem. If it doesn't, I would check the second line from the t-connector going down to the bottom of the car. That line connects into the vacuum ball underneath the car. The vaccum ball is located underneath the car by the right front tire (in the same area as directly underneath the condenser. So you would have to get on the ground and slide underneath the car (Head first) and look with a flashlight underneath the front and you will find the vacuum ball. It is a round plastic ball thing and it should have a vacuum line connected to it. Check the line and also check the ball for any cracks, etc. If the line is bad, change the line and then if the ball is bad, you can get a new one from the dealer and I also think AutoZone has them (Check their website). The ball clips on with two clips/screws to the metal of the car and you would have to pull away the plastic flap of the wheel wall to see those two screws.
Please send me vacuum diagram for 2000 astro. Thanx

Replaced radiator, new radiator cap, new radiator fluid, replaced thermostat, replaced heater core, replaced water pump, mechanic checked all vaccumn lines and performed smoke test on vaccumn lines to check for leaks, replaced T where vaccumn hoses connect and a few other minor parts, but still the same problem. Mechanic says he doesn't know what else to do.
I getting tired of taking the van back & forth to the mechanic with no results. Currently 228,000 miles. Can anyone solve my problem?
God Bless,
