The hose you showed going on the heater vacuum control valve doesn't go there it goes on the front of the valve in the middle of the round part of the valve.

I have a similar issue with that vac line not connect. My issue is I don't know where the other end connects as I don't have a line there at all that I can see.

This saved me lol

Thank you so much for your video. My AC in my truck just did the exact same thing and 96° F temperature. I stopped along side of the road and popped my hood and Sharon off my tube was broken off. I removed the rubber connector and pushed the broken out piece, and reconnected the two. Now my AC is blowing again through my vent. Thank you again.

dude saved my ass my turbo blew off my race band when i put it back on i guess i knocked that line off this video saved me so much time thank you thank you

my gray and green solid lines were severed, something rubbed on 'em

Thanks Kyle. I appreciate your share on this.

Anyone else have an issue when the EATC has no power? I've tried the automatic lights on and off trick and my climate control still won't turn on. I changed all fuses that was still good along with relays. I was praying this hose trick would be the one but I still have no climate control

Ha! Wife has been complaining for a few weeks that when she drives the truck (which is rarely) AC is stuck in defrost. I really didn't want to dig into the system, so KZbin here I come. The first couple vids were standard issues (pump, EGR, ...), but then I stumbled onto this one. When you got to the part about the hose being disconnected back by the oil fill, the lightbulb went on: I had recently replaced the glow plugs, which meant I'd taken the fender liner out, which is likely when this happened. Oila' - problem solved. THANKS!

Chased my tail foreverrrr on this exact problem. The hose had a melted spot on it. Thank you my guy!

Mine was the plunger behind the glove box, great video

This was the problem on my 05. Searched and searched. Thanks so much. Save me some money

Thanks for the video that spend zero dollars to fix the problem thanks again

Dude thank you so much! I’m sitting in 104dg heat and this was a huge help! Thanks again partner!

Just THANK YOU..SERIOUSLY THANK YOU

LEGEND

KZbin to the rescue again! Thanks for the video. Fl to hot to have your ac coming out defrost.

I’m happy this saved everyone time. Unfortunately I may need other mechanics to help out with the additional questions. My apologies to those of you that weren’t able to fix the problems.

Mine line was off too, but it still doesn't work. I can hear air/suction in the suction pump after I turn off the motor, so I don't think it's that. I think it's that thing attached to to side wall.

I’ve been trying to figure this out for weeks now, most helpful video ever man thanks

Thank you very much for posting this video. I replaced my entire a/c system about 7 years ago because of black death. It cost me $1200. My vents stopped blowing and I was thinking I was going to have to do a complete replacement again. I watched your video about the little vacuum hose and sure enough that was it. I put it back on and everything is working great. Thank you and KZbin.

Thank you! Problem solved. Good information given quickly. Thanks!

Thank you!! Keep up the great vids

A/C stopped blowing out vents when it was 90+ out. worked in the morning then just wouldn't go thru vents. checked the hose like you suggested and volia ! working now . THANK YOU !

I see that vacuum line connected to the front and to the back. Which is correct? I've been over mine new vacuum pump/ solenoid I capped off the vacuum lines to my hubs and my AC works but it's a weird situation... I put it in 4x4 it'll blow out the face vents for a couple of minutes then switches back to defrost I put it in two wheel drive it switches back to face vents I do that over and over any ideas

Thanks a bunch, the vacuum tube on mine must have been inadvertently knocked off when I was replacing my turbo solenoid, since they are right next to each other. Gotta love you tube. Thanks Kyle!!

This was exactly what happened to mine. Thanks for the video

Thank you! Looks like someone at the shop left the vacuum pump unplugged after some diagnostics on my truck and your video showed me exactly where to look so I didn't have to bring it back in!

Just stumbled along this video and for the death of me was having issues and with this video, found my 05 was not plugged in wish I found this before spending money on parts lol. THANK YOU.

Thank you for the multiple explanations and things to investigate

Think that solved my issues

Yep. Helped.

Yup, that's it, a broken line. Glad I found it before buying any parts. Thank you.

I do have question regarding the part close to your firewall. Where your vacuum line is plugged into is the vertical nipple towards the back, what’s in the front horizontal position? The vertical one on mine has nothing but the line going to the front horizontal nipple is broke. I rigged a small fuel line and it didn’t help.

What’s the part behind the glovebox called

Thanks Bro

I have a 2003 F250 5.4L 2V, Gas. My A/C would move to defrost under acceleration or heavy load (up hills). Issue was with the vacuum solenoid. There is no vacuum pump on a gas, no matter what the internet says! Part I used was Dorman 600-402 4WD Hub Locking Solenoid

Fantastic very easy fix thanks you absolutely saved me time.

That same vacuum line was disconnected in my truck too!

Thanks!!

Helped a lot man, appreciate it

Thank you!!!!!! Yes that line was off. I was ready to start spending money!!

Dude thank you so much a true king!! Had the same issue. Heck yeah man 🙌🏻

All u did was block that hose off , if this worked kool, I just don't see how .

Not where the vac line goes, u didnt fix shit

Thank you so much for this video I totally just fixed my own truck.

My vent quit blowing. I freaked out. Came to KZbin watched your video and it was as simple as the hose came off just like yours. Thanks for putting this on KZbin. It saved me a lot of work and money.

Thank you so much I did some turbo work and that’s what I left off

Thanks, the guys changing my oil knocked the line off. You saved me a lot of time and frustration. Thanks again!

Thank you!! I had a loose vacuum line!
