Wow - 2016 F350 started acting up on a long 5-day camping trip - found this, tried it, just ran through the desert north of Vegas and barely had to have the fan on - 105 degrees outside, 70 on the temp inside... thank you!
So helpful! Its funny how every other video on this topic references taking the entire dash out and the month long, tedious process it entails to do such a thing. Just cut out a hole, spray water, tape it back up, done. Thanks so much for the common sense, that just doesn't seem too common.
i used a larger 1/8" thick HDPE black panel and added light silicone on edges of hole screwed the HDPE panel on and now i have a sealed hole and can be removed for future clean outs....which i had took pics for reference
I'll be doing that shortly... currently my blower feels like an asthmatic gerbil breathing it's last breath and I think 10 years of border collie fuzz has done a number on the evap coils.
I’ve got the same truck and wondering if this is my problem. The air is still cool but when the blower is on high or medium it sounds like it’s struggling, kinda like it’s off balance. Lower speeds it cools but not desirable using it only on lower speeds. I replaced a burned out blower 2 yrs ago (NOT FUN) and it was fine until about a year ago. I definitely do not want to go to a dealer since they almost want me to finance a new truck just for repairs 😂
we have air valve with foot long metal tube bent 90degress at end and mashes almost flat we use to blow air filters and radiators before we wash .... So dirt doesnt cake up
@leewhisenant4459 pressure is impacted by airflow. The gouges and pressures will tell you where your air flow issue is. Condenser/ evaporator based off high and low side pressures. Gauges tell a big story if you know what they are telling you
My truck started acting up today, no air volume. Came across this video and figured it was worth a shot, so I cut the hole and rinsed with water. Blows better than it did in years! Thank you so much man, you saved me a bunch of headaches!
@@tylergrabin5288 I know for a fact the 2015 F550 super duty work series bucket trucks does NOT have a cabin filter nor a housing to hold one. If you have the round air vents, not the square ones it has no cabin filter. Its almost like the work trucks are using the 2010 interior before they started using cabin filters in 2011. The blower motor pick up under the dash straight sucks the dirt off the floorboard pushing it into the evaporator. I can tell this guy is dealing with a work series super duty because of the glove box design and how far the evaporator is to the right side that is were the newer design has the cabin filter just under the airbag between the blower and the evaporator air box.
@tetsuonabiki my 2019 f250 has an air cabin filter. I've changed several times ans it never helped my air flow issue. Debating whether or not the coils are clogged but don't wanna cut it if it's not dirty.
@@tylergrabin5288 of course your 2019 has a cabin filter they didn't have them in the generation pre 2010. 2011 and on was a new generation with cabin filters. But the work trucks made after 2011 they were putting the old style interior from before 2010 with no cabin filter. I'm starting to believe you can't read or have poor comprehension or just didn't read anything I typed in my previous post. So I'm not responding anymore to this silliness. God Bless and Godspeed, my friend.
Ha! You just made me look like a pro at work. This fixed our AC problem. I even went as far as cutting a plastic piece from a bucket and fastening it with short self tappers so it can be easily cleaned next time! Thanks for this video, man! 🍻
@@Alee6.7 your HVAC box has a drain. It should drain forward and come out by the passenger front tire. There is a drain tube that comes out there. Unless that drain is clogged, it will drain itself.
we have a pet that sits down there on the floorboard. There was 3/4 inch of hair n crud and had to pull out $3.800. with all new parts. it was hard pack like felt
As long as your drain tube isn't plugged, the water will drain out of the airbox. The evaporator produces water when your AC is working, anyway and it has to drain somewhere.
Hey man, like the video. So I have a 2009 F150, but the evaporator box and everything looks exactly like this behind the glove box. I'm having the same problem..airflow just isn't very strong. Once you cut the hole in the box, what is the gap between the evaporator and the box?..just want to make sure I don't run the saw blade too deep. Also, and this may be a dumb question, but it appears that it's totally fine to run the water in there and it just drains out no problem?
For the Super Duty, there was at least a couple of inches between the plastic and evap... Just be extremely careful with whatever tool you use. The oscillating tool that I used worked perfectly. Also, yes as long as your airbox drain is open, putting water in there is not a problem. If the drain is clogged, you might flood your floorboard area or fill up the vents passages with water.
Thanks for sharing brother. It sure is miserable when your ac goes out when it's close to 100 degrees. It's been one of the hottest summers I've been through.
I had my system profesionally cleaned.. It was expensive. The evaporator side was truely clogged like a thick rug. I wish I could filter the dirt before it reaches there.
evaporator plugged up...it's inside truck. condenser is in front of motor. i did that on the condenser under hood of truck on my 96 f250. peeled back cover, took to car wash and blew it out..then took metal tape and pieced it back together.. worked well..thanks for your efforts
Your evaporator case was under the hood against the firewall on the passenger side right? All I had to do on my 07 f750 was to remove the blower resistor assembly and rinse and blow out the evaporator coil. No cutting was needed.
From all the research I've done recently, cabin air filters were not added until 2017 - although there seem to be some dealer-installed options. My 2016 does NOT have an air filter - take a look at a few of the videos for replacing a cabin air filter on the 2017+ trucks and you'll immediately see the difference in the older models.
the dirt is all on the opposite side. The blower motor blows from the other side. So....... you don't want to blow any dirt thru the evaporator, but blow it back out the way it entered.
No, the water goes out of the drain inside the evaporator housing. If that drain is plugged, then it will fill up the box and could eventually soak the cab floor.
Use a circle saw and leave part of it uncut. You can then bend plastic back and cover with ac tape, hardly tell you were there. Also spray with evap cleaner. This works good since Ford in its wisdom didn’t put a cabin filter on system!
Haven’t had AC in my 2010 f150 from February-May. Ford wanted to replace everything. $3500…I went to kwik kar and they replaced the compressor and flushed the condenser. Worked great for the past month. Now it’s blowing hot again. Wondering if this will help at all or I need to look for a leak in the system.
If your compressor was truly bad, debris from it could have traveled to the condensor and plugged the very tiny paths it has for the freon to travel through. Flushing on newer condensors I have read will not work because of this. It's not that much more expensive to replace it. Along with the drier bottle/accumulator and orifice tube (if it has one). In this case Ford probably had it right, unless they were wanting to replace evaporator (in dash). 3500 is steep also. But now you're having to get into it again. Flushing should mostly be reserved for wide open components like hoses and evaps just before reassembly.
My a/c was doing this and I knew to change evaporator coil, but now it's only blowing 65° through my vent. Any ideal what could have went wrong. Used to blow 50-55° easily
Will this help with making the ac run cooler? I took my truck to the dealership a few years back n they said I needed a new evaporator they want close to 2k to replace it I’m trying to avoid that. It’s still working heat still works and when it’s not super hot out we’re talkin 70s or below it blows reasonably cool air but anything over 70 it just seems to be warm air coming out
Really doesn't change the temperature, but it increases the flow of air. Does your Evaporator have a refrigerant leak? If your system doesn't have any Freon, it won't blow cold at all.
@@tallfarmboy tried Freon awhile ago it’s loaded I think the dealership is jus tryna get money outa me it doesn’t seem to be a flow issue if I throw it on max it pushes air well. I watched another video and a guy said it could be the evaporator temp sensor apparently this is a common issue with the 2011 6.7s so I’m gonna try that you can get a temporary one for cheap on Amazon I’ll hook that up and if it starts working I know what the real problem is
If your evaporator is clogged, it will prevent air from flowing through the fins properly and wont blow as cold/or cold at all. I've seen it plenty of times. The evaporator in this vehicle wasn't bad at all compared to what I've ran into in dusty climates.
The condenser coil is upfront by the radiator you are working on the evaporator coil that is where the refrigerant “evaporates” and to be honest, the coil did not look dirty when you exposed it.
