In this video I have a look at an old school vacuum HVAC system on a 2003 Ford F-150. This one the customer originally complained about "No A/C." Come to find out, it is more of a problem with the mode operation than lack of A/C. -Enjoy

Nice video. I bet 9 out of 10 jalopy owners would leave it unrepaired.
$1,100 dealer charged to replace ours in July.
The extra wire on the panel is an on/off passenger airbag switch. I have it on my 2002 f-150.
Hey my vents blow Heat all the time when it's on hot and it blows cold all the time when it's on cold but when I drive is costly heat coming from all the vents even the floor vents and when I cut the heat on to try to defrost the window it's a smell of like antifreeze and it fog the window what do you think it could be
Mine only work on defrost and low and hugh
The Ford computer has dozens of adjustments—like turning off the dinger. You can even turn off the artificial engine sound.
Hi Eric. I have a f150 2006. I have a problem with my switches if I turn my seat heater on it turns my dashboard on instead, if I put the air on my feet it turns the air on on a different setting. What do you think is the problem?
I have an 07 grand prix gxp and my AC went out. Compressor wouldnt turn on. A mechanic told me it was my controls so i went to the salvage yard and replaced the controls and it worked, for a couple of days and now it doesn't work again. Any idea what i should try next?
I have an 03 F150 this was the first thing I fixed on my truck when I got it. You just need to replace a few O-rings, there are videos here on YouTube on how to do that. Could have had the whole job done in under an hour. Too many uneducated people just replace the HVAC head unit which is a complete waste of time and money.
I have the earthquake cordless 1/2” impact & 3/8” ratchet because Eric O. uses them, just sayin.. & so far after a couple months I’m very impressed, On another note I’ve had a earthquake 1” air powered extended anvil impact that’s been taking off big truck wheels for prob 9 yrs with no problem!!
Guy, I really like how you actually test for functioning before you make your conclusions. Old School Mechanics! Not tought in classes anymore. (40+ year master tech here, forced into retirement)
vacuum tubing and fittings are the most impossible things to keep around, they vanishing thin air non stop!!!
use a tee fitting, then you can have the gauge reading while the vacuum actuator is connected, way easier to tell if they're leaking or a linkage/damper is busted/stuck, unless you can hear the hissing. but that's kind of hard with small lines and big pots buried up in the dash
e-bay offers these units refurbished for $49.99 with three day delivery…check it out. Common problem in Crown Vic's
Give me back the three way fan switch and the two slide levers. They never broke.
loving nick starks suggestion
Lets see if we can fix it
Please turn off the door chime… Come on Mr O. . jk : )
So the controller just "sucks"!!
Shoot no field trip to the u pull for me ma'am said no (last time I brought 2 cars home)
Is this the place giving away used impacts?
Well that job sucks….and blows….
Great video Eric O
FordTechMakuloco has a video on how to fix this and it is really simple to do. Shoud check it out
These stupid fords. Them interior noises
Eric….Question In theory shouldn't I be able to diagnose this with a vacumn pump also?
Eric,
As always a great video and diagnosis. The minute I started watch I recalled that you had a similar situation a few years ago on a late model Crown Vic/Grand Marq and that my recollection was that you disassembled it and replaced the internal o-ring seals. If you do go salvage yard route please take us along. I see lots of those units on ebay for $100-$150.

God bless

And he writes, Check out YouTube channel, fordtechmakuloco. He has a video showing how to replace the O Rings on the control box from a ford 150. I’d like to see your take on tackling this repair.
Spending most of every day doing electrical repair, it is interesting to diagnose a vacuum driven system. Even so, fundamentals are the same! Tubing can have holes (short to ground), or get kinked or plugged (open). I wanna see you do a vacuum drop test, ha ha. By the way, those tubing connectors look a lot like the connectors used for garden irrigation sprinkler systems. Lots cheaper at the gardening section of the hardware store compared to automotive parts stores, and I know they work for windshield washer tubing connectors, too.
Hey Eric, this might help you with this, " Ford HVAC System Stuck on Defrost: EATC Control Head Repair " by " FordTechMakuloco " here on Youtube.
Can we get a link on where to get the napkin?
Did you end up replacing the o-rings or going to the junkyard and buying another controller?
Got my muck boots and rain jacket, let’s go pick some parts. I’ll bring the coffee.
Yo Eric you should got a little Pom-Pom and let the air blow on it😂😂
But wait there's more. Lol
Before i even watched i knew it was those stupid solenoid orings…done half a billion of em..
Im getting deja vu, didn't you do this with a Vic a while back? I wish I lived l close to you, I bring my Grand Marq and let you chase down electrical gremlins. If ya ever had to Panama City Beach, FL let me know! Yep, Fuck Pick-in-Pull…
Power probe, vacuum edition! LOL
Thanks Eric. Good to see you working with air for a change. Love the channel.
Nice Diagnostics! I saw your article in Dec 2018 Motor Age. It was about the 2007 Honda you changed the cam gear and timing belt. You did some testing with the Pico Scope to show where the problem was located. The "bad" gear looked and tested (with your digital calipers) good, but going with your gut instinct, it worked! GREAT ARTICLE. Didn't know they used the picture of you holding the gear at the beginning of the article also as "Figure 6!" Took a little looking, then low and behold there was the answer. Like you, I didn't see any thing bad with the Honda's cam gear, but you made the correct call. GOOD CALL! This video is cool. I had to to do one of these with one of our vehicles at work, PRAYED it would be the controller or the vacuum line, wound up being a bad diaphram . RATS! Replaced part, all's well with that vehicle.
FANTASTIC CONTENT AS ALWAYS. EVEN FOR HOW CRAMPED THAT FOOT WELL IS, ERIC STILL GIVES US SOME ELBOW ROOM. THANKS
The mystery connecter is for an automatic 4wd knob
WHAT WOULD PHAD DO?
My '89 Buick uses a similar system. Same vacuum accumulator, check valve. The mode door controller is called the "Programmer" and controls the blend door and
vacuum motors.
Many of those units are easily repairable. The rubber seals dry out.
Squirt a couple shots of silicone in it, freshen up the seals. Exercise it with your
mighty vac and Power Probe.
Good luck at the P&P.
Waiting on part 2. Anticipating the pick n pull.
It does that warm up and freeze crap in NY too? Had a blizzard in November, 50 degrees in December, and another blizzard is coming this weekend here in IL.
I would've just sold the truck.
Man, you're a great dude going out of your way to get parts for these cars/trucks that you work on, and for as cheap as possible.
