I got a call from a guy in Las Vegas, he could not control what direction the climate control air was going. It was going on the windshield no matter what selection he made on the control panel. This video shows a quick and easy fix for his problem.
This is likely the same on most mid '90 model Ford vehicles, maybe more. He had a Ford F350 but I found the same system in the F250. I would guess that the Ford Explorer, etc. has the same system. - Авто та транспорт
I have a 97 f250. This is exactly what I was looking for to help with my control panel issues. Good job
Thanks for watching
Just bought a 95 f350 and the ac works just blows out defroster, this is the information I was looking for. Thank you sir.
You are welcome
Robert. I watched your video, walked out to my 1992 Ford F250 XLT, found the detached vacuum hose, and fixed it in moments. God bless you sir!
+Ted Hartman Glad it helped. Thanks for watching.
Exactly what I needed to see. My vacuum system was all disconnected.
Ouch!
Thank you so much for your video, Robert. I have been breaking my head for a while trying to find out how to fix this issue on my 96 F-250 and you nailed it. God bless you!
Thanks for watching.
Thank you -- you are the only one to show photos this clear. Also, you were thinking out loud supposing what each line did - you nailed the correct colors and the operation.
Cool, thanks for sharing.
I spent hours under the dash trying to diagnose a servo issue, they all looked good but still had a diverter problem. I didn't realize there was one in the engine compartment until watching your video. I replaced that servo and now good as new! Thanks so much!
Kevin Tyrrel Good deal. Thanks for watching.
ok - I found your link, extremely helpful for the problem of defrost-only heat. I studied the vaccuum lines on my '02 F250, and found a disconnected fixture next to my battery - that I had to replace not long ago. Must have knocked it loose in the replacement. Even tho your video displayed an older model - you are right in thinking 'just study the lines' - and your piece showed me where to look and basically what to look for. I posted this link on the Ford Enthusiasts page on two strings dealing with this topic. THANK YOU, ROBERT!
+Jim Reeverts thanks for watching and sharing
Thank you Robert! Great job, very clear and informative. I enjoy your videos, all are informative. Thanks again
8 years later and your videos are still helping people thanks man!
Happy to help!
Awesome video Robert. You just taught me a little bit more about my vehicle that most mechanics don't know or have forgotten.
Ouch
Great video. I have a bad white vacuum line and you showed everything from beginning to end. Now I understand how the system works. GREAT JOB
Thanks for watching.
Hey bro! You are the BOMB! You helped me get my air-flow selector back online . . . Less than 1 minute into your video. Thanks and my best to you!
Thanks for watching.
My friend, you are a chocolate angel.....I have been beating my head against the wall and have watched everything I could. You just fixed my vents and my power brakes. They stopped working the same time. The vacuum system had a leak so I had no brake assist. I replaced every part and it is a $2 vacuum hose. I wish I had just mailed you the money I spent chasing your solution. Thank you my friend....J Sullivan, West Texas.
Me too. 😜
I had to sign in and like. You just saved me a whole lot of time. God Bless You!!
Thanks, and thanks for watching
My Wife bought me a 2000 Explorer for my birthday and there is a problem with the controller for air direction change. Thanks for sharing this info with me because it has me started on the right track !
Good deal, thank you for watching.
Very articulate and accurate. I've 40+ years in the business but neeted information on two item that you covered. 2 thumbs up. Great job
Thank you for watching.
Thank you! I am trouble shooting the AC on my 92 F250 truck and this will help me figure out some of what I need to check. Great instructions
you are welcome.
Good job on the video! I found out almost all i needed to know about my climate control and that servo by the blower motor.
+Mark Estrada thanks for watching.
I have watched at least a dozen videos regarding this and this by far is the best one thank you for your help
You are welcome.
Great video! Thanks for the step by step information. Found my leak and got it fixed.
Glad it helped!
So at 5:30 AM after watching the video I went out to my truck raised the lines and noticed that in taking out the glove bo and moving the temperature selector to see if it worked right ..it looked like the plastic part was busted and they had sort of wired it but as soon as IO pushed the line all the way over it seemed like the AC got much colder...granted it is 6 am but I feel like was the key and your video made it possible so THANK YOU I live in AZ all summer so no AC Sucks big time Thanks again!
You are welcome.
Awesome video. Really broke it down to basics for me.
+Brian Thomas thanks for watching.
Thanks for the video. Found my linkage to be disconnected, and I fixed it in 15 seconds after watching.
awesome
This was/is a very helpful video. Thank you so much for taking the time to make it.
You are welcome.
Very good video. Gave me some ideas where to look for my heater control problem. thanks
You are welcome.

awesome video getting ready to purchase a 94 f350 7.3 idi turbo diesel and the guy told me the ac vent selection knob like you described just recently stopped working, now i have an idea on what to do to fix it.
cheers
+Brock1 cool, thanks for watching.
The best way . Thank you brother I,ve fixed my car myself after watching that diy video 👍
Very good.
This video helped me out so much. I bought a 1992 F350 that a squirrel had lived in and gnawed through the white vacuum line under the hood and I was having trouble figuring out where it went. Very detailed video. Thanks.
Thank you for watching.
Good video. Didn't quite have what I'm looking for but atlesst I know how to get my controls out now. Thank you
you are welcome.
Mr. Robert. Heapings of God's blessings on you. I have been collecting these OBS Fords for a couple years, learning lots from youtube and teaching myself plenty, too. This is in the Top 10 for DIY help for this blue oval fan!! I have vacuum lines flopping around the servos in my engine bays and under the dashes of all my old trucks. I'm gonna invest in a bulk of appropriate interior-diameter hose (probably the more durable, thick, black hose for hydrualics) and mark all of the existing and replaced vacuum tubing with various colors of electrical tape and Sharpie lables. I'm psyched to get started, now - and especially to have performance (for EGR and smog system) and climate control restored in my fleet.

Good info and thank you. It was not the question I had but it was good to know info
Thanks for watching.
Yes, this info was excellent. I recently purchased a fully restored mustang gt and the motor was converted to carb. So of-course the harness was cut! This makes sense now. I need to create the
steve lawrence Maybe you can tap a port in the intake manifold.
Your video is so helpful. Very thorough!
Glad you think so!
Thank you for sharing your knowledge; you are a hopeful solution to my problem. Thanks again.!!!!
Patrick Biron Thank you for watching.
You are awesome my man! Just fixed my truck
Thanks for watching.
Great video and well explained!
Glad you liked it!
Thanks for the vid!
Followed Roberts video on heater control & found white vacuum line totally gone under hood on passenger side. Live in the bush in Alaska & minus 40 to minus 60 degree temp hard on rubber & plastic parts. Didn’t have access to parts place so improvised, as often happens in bush. Took a section of phone line& stripped internal phone wires out. The phone line worked& got good heater control. Was warm all the way to town,120 miles distant.
Very cool. Thanks for sharing.
Thanks. Mine just blows through the defrost so I definitely have one of those vacuum lines disconnected. Was working on the engine today and must have accidentally disconnected one and when I went out later the a/c wasn't coming out the vents. Just the defroster. 97 degrees today. Don't need defroster. Thanks buddy..
You're welcome!
White vacuum line to actuator under the hood on passenger side was totally dry rotted. I haven't seen any thing else yet but thanks a lot.
+Tempus Ingcognito thanks for sharing.
Good info going to check my vacuum lines getting very little heat from defrost and not very much air flow climate control seems to not go completely to hot knob feels springy like something holding it back
+Noel Garcia may have a stuck door.
Great video! No more sweaty ride
Good deal.
Well done. Helped a lot
cool
Nice job what I was looking for
Good deal.
Excellent video amigo, thx!
you are welcome.
Very help full thanks for the information
You are welcome
Thanks for a great video!
My pleasure!
thanks for your information, it was helpful
You're welcome
Great video mate..... Stay safe
Will do
I must say brilliant for going to a junk yard. Especially one where you can pull parts. That way you could show the details without the worry of oops, broken, and replacement.
+chris sorrells lol, it is a great place to practice. I was making the video for my brother out of town.
Perfect! Solved my problem. Bless you!
You are welcome
Simple statement, Thank you sir!!!
You are welcome.
Thank you it helped out alot Great video 👍👍 ⭐⭐⭐⭐⭐
You are welcome
Awesome video!
Thanks for watching.
well explained brother
Thanks for watching.
What a gem of a video
You are welcome.
Damn good video sir
96 explorer 5.0 vacuum not opening up face or floor vents, couldn't find vac relay under hood so it might be under dash like you showed thanks.
+michael crowe you are welcome.
Really helpful, thanks.
You are welcome
Great information. 🙏👍🏻
thanks for watching.
Man. That opened my mind.
Thanks for watching
YOU THE MAN ROBERT
Thanks for watching.
Wasn't what I was looking for but nice video and informative thank you.
I was wondering if you know of any solutions to replacing the climate control temperature adjustment cable on the back side of the unit. I am not sure how to get the old cable off the back side with out potentially breaking the plastic mount. It looks to pop off and I can destroy the old one without getting too upset but obviously do want to break the new replacement plastic mount putting the temperature adjustment cable back onto it. I have been looking online but haven't found a video on how to get the cable off and back on without losing my cool and just snapping the brittle plastic. The plastic vacuum connectors are broken so I am planning on replacing the entire unit with a newer one and that includes popping on and off that temperature adjustment cable. Any suggestions are greatly appreciated...thank you. 1994 Ford Bronco
My guess would be that the dash would need to be removed.
Awesome video, Great explination. Not quite what I needed though. I took apart the Selector switch and need to put out back together but need a break down of it. Any help is greatly appreciated!
I have no idea.
I figured it out, thanks for replying tho.
Good info. Thanks
You are welcome.
Very informational video. I think I have the same problem with my 98 expedition that I bought last night. I have both heat and A/C, but the A/C only comes out of the defrost, and the heat only comes out of the rear floor. Sound right? Thanks!
HomebrewDr M I don't know, it has been a while.
Good video thanks
You are welcome.
helped me fix my ac thanks
You are welcome
I know this is an old video but I was having issues with my AC stuck on defrost and sure enough I had no idea it was a vacuum controlled unit. so I followed the lines found the broken culprit and the main line was disconnected. I will like subscribe and share thank you
Thanks for your support.
I have a 1993 Bronco XLT. just put a new heater core. but it only blow out from the top. and won't blow from middle vents or floor vents
Bad linkage or vacuum.
Thank you! Thank you! Thank you!!!
stephen2039 Glad it helped.
Thanks a million 😊
you are welcome.
Good Video Robert. I have the same truck and was having trouble switching the temperature control knob (middle knob) from hot to cold and vice versa. It will eventually go, but I have to slowly walk it around a little at a time, otherwise it feels like it may break something. what can be done to free that up.
Probably a jammed blend door.
Did you figure this out? Not getting heat from mine.
Geat info !! can you explain how to change out a blend door in that same style truck .mine has the lever broke off the top of the blend door
lildoob72 I can try if you give the the vehicle specifics. My guess would be that the dash would have to come out, then the duct system.
its a 1993 f350 1 ton 4x4 with a/c
OK, I'll check Monday. Remind me if you don't hear from me by Wednesday.
Is there any video on how to remove or replace the temperature knob with the cabel instead of electric connector?
I have no idea.
Thank you sir
Welcome
Thanks buddy!
+Frank Woleslagle you are welcome.
Thank you
You're welcome
Wish the year was in the title. Nice vid though. Best Wishes/Blessings. Keith
+Keith Noneya Should be in the comments.
Sherlock home boy.. I like this video!
Awesome! Thanks for watching.
Thanks 🎉
You're welcome 😊
I need to create the vacuum somehow. Any suggestions?
steve lawrence They rent vacuum pumps at auto parts stores.
i have a 92 cadillac deville an have the same problem air only flow thru deforst
joel lewis Some diverter has stopped working or come loose.
Ok thanks I'll check
What does that last servomotor do that's in the engine bay in the passenger side do? Is it to close the damper to recirculate the interior air instead of allowing fresh air in? That's the only one that's missing it's vacuum line, everything inside my truck is hooked up but still only has air coming out of the defroster. Any ideas?
+Clint Garza no I don't.
You could hook up the vacuum line to see what happends...Just a thought.
...But it is the fresh air door.
Man i’m so confused i’ve looked everywhere online for hours and can’t find what i need, and i think i ordered the wrong parts after seeing this video. my switch for the MAX AC/VENT/FLOOR broke today when i went to switch it to ac, and it’s stuck on vent. all of my vents and what not worked perfectly before the switch broke. All i need to do is replace the switch, however it looks from the backside there’s two different switches on the right side.... so which one the hell do i need? is the switch even replaceable or do i have to get a whole unit with everything together? HELP! lol. if it’s the switch on the bottom with vacuum
lines attached to it then i ordered the correct one.
If you were able to order a switch, you'll probably be fine.
I've got a 2003 F-250 diesel 6.0. My problem hasn't been discussed anywhere.. My hvac blower stays on high even with the control panel in off position. When I turn off ignition it will stop!! Any ideas would be greatly appreciated..
bad relay.
@@RobertDIY
I knew that but my mule headed nephew disagrees ! Thank You Sir. Keep the videos coming. They are greatly
Appreciated. Happy Thanksgiving to you and yours!!
i have a 2003 ford excurision, when in a/c mode the air comes out of the defrost vents, the vac pump was changed, then when the cab goes above the set temp it returns to the defrost vents, i raise the temp and it returns to the dash vents,then lower the temp, i have to keep doing this until i reach the right temp, hope someone can help
I really have no idea unless you have an electronic controller that has gone bad.
I'll bet when they replaced the vacuum motor they plugged the lines in
backward.
Also on photos of your middle cold and hot and your head will work I have a 98 Ford explorer and that's what I did if that will have tried it
Interesting
Hey Robert, sorry to post off-topic, but do you have any information on Volvo 850 (1996 in particular) heaters being too hot? I live in a fairly warm place and have never used the heater since I bought it until recently, and it get so hot, even at fan level one, that it melts plastic. Car's temp is never goes above 182-185F, but I have no clue with what it could be. PM me if you don't want to reply here.
PM on it's way. I do have a Volvo heater system video.
Was is a diesel truck having same issues but our trucks dont make vaccum wording how its done
ok
How did you connect the white wire
I don't understand the question???
i forgot to say that it has a digital control head and a 6.0 diesel
Thanks ! I love the Internet ….
LOL
My climate control has no current at the connectors on my 97 Tbird
+William Jefferson ouch!
What could cause this? My led shows temperature, 12volts to the blower motor makes it comes on, if I supply power through the resistor, the switch controls the fan speed but if I hook it up regularly there's nothing. Is this a bad fuse problem??
William Jefferson not sure I understand but a bad resistor can cause the fan not to work
Those vacuum lines get brittle and break by the engine.
Interesting.
