finally someone explained why it stops working and not just replace this and that

Thanks to you tube videos I fixed the worn piece of hose and my ac is working like new again. Thank you !!!!!!!!!

After weeks of trouble shooting to no avail, I did this today and, voila, my ac works better than perfect now.

Awesome video . Thanks for your help. Very descriptive

You just saved my life!! Thank you Sr. 👍🙏

I'm going to try this tonight on my expedition thanks for the video

Thank You just fixed my 09 E350 travel van!! You Rock!!

I'm going to give this a try, mine switching from front vents to defroster vents when I accelerate.

Just bought a low mileage 03 E350 w same problem. Maybe this will fix it...thanks for posting Mike!

Best vid so far on this good job

You are the man Mike! Vacuum canister, who would have thought. My 2002 looks a bit different but maybe I'll figure it out. Thx

Extremely helpful!!! Thank you.

Thank you for the video Now I know where the problem is highly appreciated

Amazing thank you thank you thank you every mechanic said it would be hours and it wasn’t worth it. This literally took an hour.

Very helpful... awesome thanks

Going to give this a try. Thank you

Thanks Mike 😊

Thank you so much

Gotta fix mine hopefully this works thanks

Now trying thanks a lot

Wow, you are a genius

Sure do miss the manual vent doors😂😂

Thank you

Thank You!!

Thanks Mike! This has me going in the right direction! 2004 E450/Winnebago. One question. Before I begin, the scenario of the A/C vents not operating under load was exactly as you say. Coming out thru the defrost upon accelerating. But now, it is a full time scenario. Idling or accelerating, the cool air is only coming out the defrost. It no longer comes out the A/C ducts at all. What do you suggest? Thank you very much!

For some reason the vacuum canister is special order in NE Florida at O'Reilly...I basically did what you did for the exception of reusing the grummet by expanding it to pass the new line. I pulled out the the grumet pushed a cablers fish through it that came out under the blower by the fender. I pulled the new line that way. Since the canister is special order and I wanted this done today, I used an inline check valve without the T connector. It actually works really well in NE Florida since it's pretty flat on all roads. I imagine if I were climbing hills it would be a different story. I will add the canister when it comes in. Thanks for the video, without it, I would not have known I needed the canister. I was originally fixing a vacuum leak on the original line.

Throttle open makes les Vacum to the littel lines.

I need to know if the metal shape snake u shape metal line to the right an after market where you put freon is connected to called

When my ac is off. Burst of warm air comes out the vent when pushing gas down real good

Hi mike compre una van ford serie -e 150 y tiene el problema que solo sale aire x el desempañador de vidrio y los que ban al piso pero en las ventilas de enfrente no sale que me puedes sugerir aser 🤔 estoy pensando aser lo del video

I have a Ford F 53 chassis on my RV and I’m having that same problem do you happen to know where the vacuum canister is on my RV it’s a class a Winabago thank you very much

How to fix on toyota vehicle? Any ideas?

How difficult is it to connect the new hose on the interior cabin-side (under the glovebox area)?

I did this repair and it's still doing the same thing. Any suggestions?

Hey Mike I Have a 2011 F150 and A/C works fine until I come to a stop and then I lose about 10° and temperature. My temperature driving is at 40° all day when I come to a traffic light or I sit in idle it’ll move up and lose about 10 to 20° and then drive again and go back to 40°. I know I have a problem with the recirculation door also not willing to function due to Ford better idea. I did find that it was broken and just positioned the ductwork in place. I had also replaced mode door actuator which I thought was bad but I don’t think so. All mode doors are functioning defrost vent floor properly. I noticed when I started up and I don’t turn any vent system on at all. Everything is shut down motor gets hot to operating temperature. I can feel blast of hot heat coming out the defrosting vent until I turned the AC on. can you help me out?

Hey Mike, interesting procedure. I’m wondering if you do anything to eliminate the existing vacuum reservoir? Thanks Mike N

Thank you so much, nice video and thanks for sharing. One thing is still not clear to me is that three way valve, where is it located? I went and checked my e450 but couldn't see it anywhere, or is hidden down with the pipe and it will come out with the old v pipe when you pull it out? Thanks

Mike thank you ... 2011 Econoline >>> I don't see the check valve ... It looks like the "red" vacuum line joins with a vacuum line that runs thru the fire wall as you indicated. However I don't see the check valve.. Where is it located ? thanks tony

Thank you sr. Your video really help to me

I can't find the part to order it. I'm at o'reilly @ the moment. Does anyone have a part number, or any advice as to where i can get the part?

How do you plumb into the small line under the dash (the line that you cut and left under the dash that leads to the controller manifold)? did you have to warm the line to get an adapter inside it, or did you do something more creative?

I had to replace from front AC B

Thank you for the video. I think that is where my problem is. However I do not see where the new line goes u der earth the dashboard. Could you send a picture?

Also, spend a few extra dollars and replace the check valve too.

Ik this is for a 2000s truck but i dont know where else to go to i have a 92 f150 4.9 and the problem is exactly this, i dont want to pay too much if its an easy and lasting fix and i want to do it at home,does anyone where i could start?

Hey do you know what size the new vacuum lines should be?

Mine stops blowing out of the normal vents and blows out of the windshield defrost. Could that be a different line?

How do you do this to a 2011 grand Marquis?

My AC switches to hot air in the vents on acceleration, to fix I shut it off for a minute and AC returns until I accelerate too much again. Different problem?

So you are leaving the old reservoir connected to the vacuum system and just adding a new reservoir?

Spent 40 bucks....broke my ass 2 hrs....still has same issue....just tie wrap the solonoid on top dash in the vent....closed position

My check valve only has 1 air inlet and 1 outlet.

Hey Mike, David here , hoping you can help me out , I have the same problem on a 2017 e450, I replaced nearly everything under the dash , including the vacumn canister and the check valve , i moved the vacumn canister inside the van, ive checked all the connections, they are all hooked up right, and it's still doing the same thing , and every video I've watched says the same thing, I replaced the vacumn canister and the check valve twice, what ami I missing ? 0:05

how do we get a hold of you is there an email?

Dude, THANK YOU! You the man!

this line that line. how confusing
