** CHEVY ASTRO VAN VACUUM LEAK/ No AIR COMING OUT OF VENTS/ I'LL SHOW YOU HOW TO FIND IT

- Video explains where the culprit is to get your A/C back up and running and how to fix it Cheap!
If your goal is to get the ac to blow through the front vents and you don't care about a functioning defrost mode simply plug the end of the hose shown here at 2:20 with some duct tape.
This hose attaches to the controls for the defrost / front vent selector and when the hose is open to the environment defrost mode is selected but when the hose is shut and a vacuum can form the front vents are selected. It's not a proper fix but it was quick and easy and got the ac blowing out the front vents of my 96 gmc safari quick and easy, which is important when it's 95 degrees out and you only get a day off from work every few weeks. My plan is to properly do the job in the fall when it's cooler out and not miserable working on your vehicle in the street. So appreciate the video you helped me to get my ac working again!
Thank u for the info!...:-)
Perfect! Worked a treat. Can confirm that if the vac hose has broken off back in the engine, behind the AC pump, then take the engine cover off. It's easy and makes access a breeze
Great info.. thanks for the tip..
Just did mine thanks to you pointing it out here! Mine broke off in the coupling and had to pull it all the way out and attach the hose. Just glad I didnt go through the cabin! Thanks again
Awesome! Glad I could help... :-)
Nice video, I had this same thing happen but I removed motor cover in side the van. What a pain in the, I like your way better after removing that air box you have no issue getting to that intake where it's hooked up. Seems alit easier. Thank you
Awesome.. You're welcome... :-)
Great video I did this on my 2003 before fixed it..with new hoses then the one that goes down around on right side broke again. So I'm gonna have take the cover off to replace the entire hose. You are right that does fix the front vents I have a rear AC also it keeps it really cold but nice to have the front ones working too.
Yes it's nice when they all work..... :-) Thanks....
Thanks! Got me back in cold air until I can replace my line. Seems like after 15 years, that plastic spot just cracks
Great! You're welcome and glad you got it working again..
I was getting ready to buy a Heat A/C control unit before I saw this. It was exactly what my problem was. Thank you. God Bless youtube! :)
That's awesome! SO glad I could help someone.... 😀
Very well only take me 2 minutes to fixing my problem good video
Delio Perdomo Excellent!
You're a saint man. Had no heat in front or rear, follow your vid and now everything works 👍
That's excellent! Glad I was able to help.. 😀
Thanks
Vents Worked before engine work
Now blower runs great
But
Just no air through vents
Did something break loose?
Replace your ac heater blower resistor
That was the fix for my 03. Thanks!
You're welcome! So glad I could help... 😊
Thank you I still have one of those old Astro vans 1995
They're good vans... 😊
Cheap plastic hosing. Did the fix. Works great. Thanks!!!
Excellent! You're welcome..
I subscribed to this guy just because he's got so much cool. 👍
TYSM for the sub! 😊
I knew I had some decrepit vacuum lines. I did the same “where the hell does that go!”. I found two. But I’m gonna look under air intake system. Those hoses and tube are really pretty chincy.
I know... Good luck.. 😀
Thanks for sharing this information. I had to pull the engine cover off to connect the line since all the hose crumbled. The vents now work correctly. The vacuum ball crumbled a while back. Do you have any videos on the hose routing to and from the vacuum ball? Now today the a/c stopped working.
Ken Sanders unfortunately I dont.....
When the rubber breaks, all kinds of trouble can occur.
True..
my vents shut off anytime I am heavy on throttle. When I ease off the throttle and just Cruise, then the vents start working again. any ideas?
Yea, I think there's a vacuum canister that's loosing vacuum. Either a cracked line or the canister itself is bad. I'm not sure where it's at on the Astro, but you should be able to google that. I've got a ford that does the same thing.. i've been meaning to fix it for like 3 years now... arrrgh
The vacuum canister should be on the other side of the rain flap on the passenger side wheel well. You'll need to remove the wheel and there's a retainer clip that you need to remove to get on the other side of that rubber flap and it should be up in that area.
@@JLPicard440 thanks for input. I went and found that the vacuum canister had been bypassed completely, throttle vacuum went straight to the heater control. Installed new throttle vacuum vall as well as the one-way valve and still same symptoms, got to love it!!!
@@ADubTheGrizzy i have a 92 with that same problem...still cant figure it out...i was told there is a check valve somewhere that get stuck but i never found it..
@@workingshlub8861 I'm not sure on that one...😞
thank, you for you're helpful video👍.
You are welcome!
6:12 Legend has it. His wife still rides the bike 🚲 before she will board the truck 🛻
Thank u.
I had similar problem. No upper vent airflow. In my case it was the heat blender actuator.
Oh wow! That sounds like a good one to diagnose and fix.... I have a ford van right now that looses vent when under load... I'll have to fix it one day. It's been a pain every time you go up a hill the vents cut off... 😂
Sometimes it can also be the ac heater blower resistor
Yes I'm sure that's true... 😀
@@Dominoid86 replaced that 2 years ago so I knew it wasn’t that. But I checked it anyways. Also replaced heater core and opened the cover for blender doors.
Sweet fixed it in two seconds didnt know I knocked it off replacing the evaporator thanks!
Glad to help
thank, you for you're helpful video.
You are welcome!
I'm overhauling my Mom's Astro ac/heat system with everthing: compressor kit, condenser, evaporater, blower motor, heater core, and the vacuum lines, O-rings, and hopefully after that it's gonna work for summer and winter for years and years later. The heat can be dangerous in the later summer months of Texas.
Wow, that sounds like a lot of work! especially on a van... but yes your right about the heat.. i used to live in San Antonio,... and it does get hot there!
+Take a Bath Productions Yep but We've known a pretty decent mechanic for many years so I'm just buying all the stuff and drop it off at the shop, labor is only gonna be $300 so I'm just gonna watch and cross my fingers. By the way how many vacuum lines does the astro use?
paul mogendi honestly I couldn't say on that point.... sorry I don't have a better answer
Where it goes the hose that is going down, I have that one broke in my gmc van
OH wow.. very interesting.. 🙂
Thank you for this video. it fixed my van
That's excellent! Thanks for sharing.. 😀
i will look at mine when it gets warmer been really cold here to check it. mine has no air from any spots but hear the sound from changing the settings from the different vents just no air comes out. so i will check the hose and go from there.
Crossing my fingers for ya!
Thats it!!!!! thanks for the THAT valuable INFO!!!
You bet! You're welcome... 😀
Very good ❤❤❤❤❤❤
TYSM! I really appreciate it.. 😊
Thank you for the video.
I'm looking for the rear door rubber weather strip for my 2003 ASTRO but I can't find it anywhere, any idea where I can get it?
You're welcome... Have you tried local junkyard? Maybe rockauto.com? Sometimes eBay has some unusual parts like that too..
Steelerubber.com it’s expensive though
@@jfick3219 Yes, but if it's the right one, it'll be worth it! Thanks for the info..
@@JLPicard440 join the Astro safari repair groups on fb very friendly people.
@@jfick3219 Thanks for the tip!
Please add a link to the "1000 year" tubing supplier. I used to work at NASA and want to pass on this "super steel" product for the mars mission, lol.
Sounds like good stuff!
at the T one hose goes to the dash the other hose goes down. Down to where is the question?
I don't have access to that vehicle anymore.. ☹️
My cousin needs your videos lol hipees...
You can get rid of hippie's by playing. Death metal! Problem solved !
The origin of these hoses that come from the fire wall has two hoses. A bigger one and a smaller one. What does and we’re does the smaller hose go too
I don't know right off hand.
What size fuel / vacuum line did you use for this particular fix? Before I order new tubing i wanna make sure i get the proper size and i dont have a caliper handy
I don't remember TBH... Is there a sample that you can bring to a parts store? NAPA has lots of different size lines they sell by the foot..
I found and replaced the hose from the left rear side of motor (engine cover removed) to the check valve on the right front near ac compressor. However, the is a larger hose that is also bad. There are two hoses that run thru the firewall. Where does the larger hose go?Vacuum problems SUCK !!! Anyone?
Garry Jones I wish I knew this one... I don't have access to that van or I'd look for ya
fixed my issue. Thanks!
You're welcome! Great to hear.
Awesome video! Nice job
Thank you! And thanks for the great feedback..
Is this the same vac line that routes to the heater blower box? I have a similar problem, and I pulled that hose off and it was full of water or seemed like water, could have been coolant from the core? Haven't checked this line you show here yet. Anyway, any advice on that would be nice. Thanks!
I wish I could help you on this one... That van has been gone for quite some time, so I can't look and see where it goes.... sorry about that...
Thank you for this!
DJ BIS You're welcome 😁😁
Nothings easy with an Astro. I've had five.
Yep... I think vans in general are more difficult to work on... 😊
Perfect thanks for the video
My pleasure!
Awesome info sir thank you 🙏. 👊🏽 Trump 2020 Victoria,tx
Thanks Alfred... :-)
What do with all the idiots (on both sides) that run this country have to do with fixing your AC lol
I like the wife on the bike
Me too!...
The two tubs that has air flow I wanna know where they connect?
My a\c thru the vents is fine until I accelerate then the cold air goes up to the windshield.
Can you comment on this issue ?
Ron Bond I have the same thing going on with another vehicle... I believe it's the vacuum reservoir and check valve... I don't know where it is on a Astro... but I'm sure it's a nightmare... there may be a way to bypass it and relocate it to a better spot... try google that and see if there's any information on it... there is on my e250 with that problem... I just haven't had time to try and fix it yet
Anyone have a hard time replacing the spring?
Thank you!
You're welcome!
how do you get the fan wish out
How did you get it back I behind the compressor?
I'm not sure what u mean?
Sounds like you connecting rod knock
Not at all... probably just the way the sound recorded... 😀
thanks this help me alot
Excellent! Thanks
I replaced vacuum hose and still no air out of vents .what now
Jerry Zimmerman you've probably got a vacuum leak in another spot.... not much of a way for me to say without being there to see it
Anyone here know where I can find vacuum line/hoses replacements? The ones for my 2000 Chevy 454 engine AC system are crumbling away. I have been unable to find anyone who makes replacements. Any help would be greatly appreciated. Thanks!
I checked Amazon and they had a lot of stuff listed there in different sizes etc...
@@JLPicard440 Thanks! I didn't realize what those things were called and was looking for the wrong thing.
@@yvesgiraud7663 Awesome... hope you found what you're looking for.
Does this also affect the fan motor speed, high and low?
No it doesn’t
Take a Bath Productions I fixed it! New resister and vacuum lines! Thanks
Dodge floor mats in a GMC
It happens!
I got same problem
Hopefully this will fix it for you.
👍
Thank u!
chevy silverado 2006 4.3 v6?
I can't answer that, but it should be close to the same
there is an thick black hose broke where it go
i fixed it using a fuel line ... permanent fix
Excellent!😊😊
In order to see where the other end goes you need to go and take off the dog house
I don't remember doing that on this one..
Dodge ram floor matt
Yep... LOL... what can I say, I already had em when I got the van...
Take a Bath Productions I'm only messin with ya. I had to be that guy! Lol
