Well, with the electronic crap they have in cars now, it can be quite complicated actually. Not in the actual working of how an AC system works, but all the electronic sensors, solenoids, blend door vacuum system or electronic actuated blend doors, all sorts of crap in these new cars to fail, even the controls in the dash fail. Simple rotary knobs worked fine LOL, all that electronic push button dual or quad zone climate control crap is what's gonna cost you lots of $$$$$ when those systems fail. Some systems use vacuum pressure to operate the blend and vent doors some use electric motors, some use a combination of both, and none are easy to get to and often requires tearing your dash apart to get to them to even see what's wrong. I like my old vehicles that just have a couple of easily accessible cables LOL.
I'm a recently divorced single woman & I tinker with minor fixes in my car.. so just wanted to say thank you for your good advice, plus you make me smile because you are so hype when you do your videos. God bless you & the fam. Peace
Who else's air conditioning system is working perfectly but is watching this because they like watching the Scotty Kilmer channel? REV UP YOUR ENGINES!
Thank you Scotty! I followed your steps and observed that the radiator fan was not spinning. Local mechanic confirmed it, and replaced the assembly. I'm grateful to you!
Scotty, this A/C video is great. As vehicles become more and more complicated by electronics and the requirement of specialized tools, it’s good to have folks like you to simplify what otherwise could seem complicated and overwhelming. Thanks. I do, however, have a question regarding your insistence on having a strong battery to ensure peak A/C performance. Correct me if I’m wrong, but I seem to recall you stating in one of your other videos that, once the engine is running, all electricity needed then comes from the alternator, not the battery. I also believe that the alternator charges the battery. Right?
Man I’m so glad you made this video. My 2006 Dodge Ram hasn’t blown cold air in a few years, and it’s much too expensive to take it in to a shop to get it fixed. They always try to up sell me on crap I know I don’t need. It’s only recently I’ve started getting into working on trucks and cars, so this will certainly be my next project. Thanks Scotty!
Keep those videos coming!!! You are the best and look out for the little man! We watch you everyday! We are going to share with everyone we know! Thanks a lot Scotty!
THANK YOU THANK YOU!!! I've come back to this video just to tell you I never knew about a cabin filter. My 99 subaru foresters ac stopped blowing cold a few years ago. After watching this video I found the cabin filter and IT WAS INSANELY DIRTY. Huge mouse nest and leaves. After cleanin it out my air is ice cold again!! Who knew 5 mins of my time would fix my ac. Thanks scotty!!
My mom's cabin filter hadn't been changed in 10 years! It was a solid black brick of dirt and leaves! She was complaining that the air smelled moldy. LOL
For those who doesn’t like your channel, they have no idea what type of infos they’re missing on. Your channel is my car life hack. Thanks again SCOTTY.
I usually use AC pro because it has a pressure gauge on the can so you know if you really need refrigerant or not. Also I just prefer AC pro anyway because the cheaper bargain ones don’t work.
I've learned from experience to AVOID the DIY refrigerant kits at the store. Most shops have a simple machine they will hook up to your system to add refrigerant if it's not within target range.
One thing I really love about your videos is that you don’t spend much time on flapping around talking about nothing to get over 10min. I got my first car with AC and I’m going to have a little look around. Thanks man for epic videos
Great video but a correction: a heat pump doesn't suck the hot air out, it absorbs the heat energy from the air. The air in the cabin stays in the cabin, it's only the heat that's removed
Thought my 94's AC was just getting tired, but I knew it wasn't the refrigerant. Saw this vid and thought I'd try cleaning the condenser. Sure enough there was a ton of crap stuck in it! Cleaned it out and sure enough it runs cooler now! Thank you Scotty I didn't think something simple as that would be a big problem!
Is your flux capacitor not working efficiently? Here's what you can do to fix it and make those time travel adventures more comfortable. First off, you gotta check it for bugs....
I needed this guy as my college proffessors...,football coaches...fire dept captain....police sgt....principal....cousin...beer buddy etc......I can listen to him all day and understand 🤣
To keep the radiator and condenser clean,,hang a screen such as used for windows to keep bugs out in front of it.. First thing I do when geting new car..
the condenser is inside the car and putting a screen in front of the radiator is going to need cleaning too. I guess it could be good in that you can remove the screen to clean it outside of the car.
Great overview Scotty. I worked on my old car often and these tips really guide someone in diagnosing a problem. In my newer car, I leave it to the dealer to fix it but it helps when you can tell them what it may be from being a little knowledgeable about the system.
Scotty please stay healthy, we need you long time. I have a 2008 GMC with 190536 miles. I just changed the oil, spark plugs, and serpentine belts. At 61 I am not too fast but I am cheap. Next changing oil on the power steering, transfer case, and differential. Then new coolant and cabin air filter. Next, next ,next ? .
Scotty Kilmer, what a genius. I watch every single one of your videos EVERY WEEK, take notes, learn a lot, and people think I'm an expert just for repeating what you taught me, Scotty. What a wonderful service you do for us DIY-ers. Love you!
the refrigerant goes into the evaporator via a metering device ( it regulates how much goes in). the refrigerant is in a liquid form into the evaporator where it boils off (like boiling water turns to steam) and absorbs heat around the coils from moving air. it is sucked into the compressor and compressed into high temp high pressure vapor and pushed into the condensing coil (in front of radiator) where it cooled back into a liquid to start all over again..
To add to the AC radiator part... Bought my '99 Tahoe in '03 and the AC rad and coolant rad had a lot of bugs, dirt and small stones embedded with a lot of the fins bent. I took a piece of welding wire and bent each end into a different hooking pattern then hammered them flat and taped a piece of vacuum line over the mid section of the wire for a handle grip. I laboriously, over multiple days, picked out all the crud while straightening up the fins as I went. I now have a 1/8th inch square holes screen over the grill which catches the larger materials while allowing air flow. This vehicle also has an add on transmission radiator mounted over the lower right passenger side Ac rad. area which would be extra cooling when trailering. I never pulled that until last year when I wanted to see what was behind it. To get to the trans radiator requires pulling the grill which was fairly easy to do. The space that little rad covers was caked with dirt and sand which I was only too happy to remove. I now have a standard piece of window size screen attached over the trans rad section of the outer screen. I am a fan of using the lye based spray cleaners and a hose for finish up cleaning. The lye is good for dissolving organic matter as well as cleaning in general.
Back in the 80s I used to drive for a limo company we had olds mobile 99 s ..200.000 + miles .. us limo drivers used to take a hose.. with a nozzle and spray ( engine off) water from the inside cowl through the radiator toward the outside... Clean out all the dust dirt and bugs that collected in the fins of the radiator... The car is used to run much cooler...
ac filter …. who knew! Thank you so much - you saved me hundereds of dollars taking this into the shop to get the ac fixed! Cleaned the filter and it works good as new!!
mine kept doing that when i was running the ac while idling out in 100+ degree wether even when i revved up the engine some so it can spin the fan faster it still did it, and it literally resulted in the ac blowing cold and warm musty air back and forth on my 04 isuzu ascender (gmc envoy) and turned out by using your car as a cooling station is a good way to harm the engine in the long term
I bought my 2009 Corolla new, the first year a rock hit my windshield and air conditioner condenser. Two separate occasions. I have had the worst luck with condenser all my life. I’m 49 years old, it’d be nice to drive a car that has air conditioner for one time in my life! UGH 😑 Ok, I’m done complaining now.
Save up some money and pay someone to get it fixed it a Corolla anyone can work on it and parts are pretty cheap if we’re talking about aftermarket stuff
@@carljohnson4996 u know what? I still have my Corolla, it’ll be 13 years old in October. I bought the 2009 in 2008. It’s now the best decision I ever made. My kids are driving it now.
Great info Scotty. I live in Washington and we only get a few months of summer so I hardly use my AC. I have a 95 Toyota Celica and the air conditioner is ice cold I have not done a single thing ever to it. I bought it in 2001
Yup, my 96 corolla's ac went out last year, it was just a bearing in the pulley, but I replaced the whole compressor anyways. It's ice cold again. These Japanese cars were built to last.
I was told that tip 35yrs ago. My wife and I have the exact same car only one month apart. 5yrs go by my ac is. Like new hers not so much. They both have new batteries and we keep up changing the cabin filter yearly.
This is very healful. I tried 2 fix my AC a couple of times however after the last 2 mechanics told me There was an escape on the evaporation system which will cost me over +$1,000 I decided 2 leave it alone. Funny how when there's cool weather in turn the AC and blows cool air, not cold but cool but when it's hot and I turn it in instantly it blows hot air. My heater works very well and good cause sometimes it gets cold down here in the South.
The AC Pro system works very well. My AC was cutting out in temperatures above 80 degrees. I had it serviced and unknown to me the shop that serviced my AC added too much refrigerant. The AC Pro system has a V shaped gauge that is adjusted to the outside temperature. It was in the red zone and showed me that I had too much refrigerant in the system. I released enough refrigerant to get the needle to fall into the green zone and my AC works perfect now.
What do you think Scotty? I tell those with AC to run it for a few minutes during the winter just to make sure the lack of use doesn't damage the system.
What vehicle do you have that your defroster is electric? Rear window defrosters are usually electric but never seen a windshield defroster that was electric.
Thanks Scotty .AC in my Toyota was playing up. Watched your video, pulled the glove box, pulled the filter out. It had mouse nest in it.Completely ruined. New filter needed. Thanks from Australia. PS the car was parked under a tree often.
I tried to fill my AC up with one of those cheap auto-zone cans of refrigerant when I was younger and broke the compressor, $300 because I didn't know what I was doing lol
Took my car to AAA Auto Repair Center on Tully Rd in San Jose to repair the air conditioning. They told me that the compressor was bad (which I had already figured out since it had a frozen clutch..couldn't push it in by hand while engine was off). I know compressors cost about $300 but they were going to charge me over $1500 to replace it. Then, later, they called me and said they would have to also replace the receiver drier and that would cost another $400 or so. So, after I went back to pick up the car, I looked under the hood and saw a nice shiny new compressor but couldn't see the receiver drier until I got home. Turns out that the receiver drier is like welded to the side of the condenser and has a plug on the bottom that needs to be removed in order to insert a cloth-like cylindrical shaped tampon-looking "drier" that takes moisture out of the system. That's all they did...and they charged me over $1900. The drier "tampon" can be bought at auto stores for from $15 to $35. And the compressor can be bought for about $300. My car is a 2014 Hyundai Tucson. Once you take off the splash panel under engine of the car and look up at the bottom of the "condenser", on the driver's side of the vehicle, you can see and access the "receiver drier" plug to remove to insert the "tampon". I couldn't drain the coolant into a collector before removing those parts so I had to have all this work done by "professionals". Funny, not, how the government will fine you big bucks if you let the coolant escape which helps contribute to global warming but they have no problem sabotaging gas pipelines like the Nordstream pipeline which belched tons of gas into the atmosphere for many days! It's no wonder we are having high, record, temperatures. Wars don't help either. Same thing happened after WWI and WWII..record high temperatures worldwide! Thanks a lot Putin...you son of a b...!!! Putin needs a "b" to the head!!!
You can buy them and add them yourself if you have the tools to do it. I did that in my 88 Ford Bronco 2 when I repaired the AC last summer, although those little inspection windows don't really tell you anything of use, other than if you do or don't have any refrigerant. You need a gauge set to actually test an AC unit.
I own a 2006 Mazda 6i and it has fewer than 53,000 miles on it that had bought it brand new. Well a few months ago as summer of 2017 was coming to an end, I noticed my A/C wasn't cooling as before. It was also taking a lot longer to cool once it got going. Well two months ago, I bought a can of Freon/collant and a hose, and with the help of a more experienced friend I got the coolant in correctly. The A/C blows cold as hell now on the lowest setting (setting 1)!!! So glad it wasn't a problem with the compressor, that was obvious right off as the compressor would kick on. That can gold got as hell as it was filling the system. haha
Hey Scotty, just yesterday my ventilation motor blower went out. Consequently, I had no air coming out from the cars vents even with the rest of the A/C system working
Jeep Life71 my jeep it was under wipers.. I had to take the plastic off.. open the hood and take the black plastic off. And it was mounted there on passenger side.. hope it helps with an 08 mine was a 00
My mother's Ford Explorer from 2005 or so (about 13 years old) has always had some pretty awful air conditioning, (due to the design where the vents connected by a leaky duct instead of an air tight duct), so last summer, I suggested she replace the Refrigerant, we got some "AC PRO" from the store and gauge on can said it was in the red labeled "Low", and so I replaced it, and the air was NOTICEABLY colder, and the car would cool down MUCH faster, later on, after I saw my father replace the cabin air filter, I asked if the one in my mothers car had be replaced, and he said something like "No, I don't think it has." *SO NOW, I plan to:* Check if the fans behind the radiator are BOTH working, clean the radiator and condenser, replace/clean the cabin air filter, and run hoses through the ducting so the vents have an air tight connection. THANKS FOR THE TIPS! :)
The only time the hot air in the vehicle is pulled into the cooling system and recirculated is IF that vehicle has that option. Most older vehicles (at least 2001 and earlier) don't have this, so ambient air is cooled and blown into the cabin.
The phase change of the refrigerant going from a liquid to a gas takes heat out of the surrounding area, which lowers the temperature of the surrounding area. The gas is then compressed back into a liquid by the compressor, then around we go again. All ac's use this model.
Same thing with home air systems make sure the evaporator coil and condenser fins are clean and the filter is not plugged solid then it should work good
Probably leaks at the connections, those dang o-rings were prone to failures causing leaks. So the whole system needs taken apart, new o-rings installed, leak tested, and recharged. I repaired the AC in my 88 Ford Bronco 2 last year for about $500 that included a new compressor, accumulator, o-rings, refrigerant, and the tools needed. About 1/3 the cost of paying a shop to do a 1/2 ass job. Pretty easy to do, time consuming and requires some tools you probably don't have but once you buy the tools you've got them for future needs too. Vacuum pump, AC Manifold gauge set, and refrigerant were the main things I had to buy but I have the tools and some extra refrigerant for future use if needed. So far so good on the AC repair on my Bronco 2. Just needed new o-rings and a new compressor.
Extremely easy to convert it to R134A, just requires swapping out the service ports, vacuuming down the system flushing the system to get all the old R12 out and the old refrigeration oil out and put new oil in compatible with the R134A, then leak testing the system and recharging. Since mine needed a new compressor flushing the system and replacing the refrigeration oil was even easier, plus I had all the pressure lines out as I replaced all the o-rings, put a new accumulator in and flushed out the condenser and evaporator, put everything back together, tested the system for leaks with the vacuum pump, then simply recharged the system to factory specifications. Took a couple hours start to finish, once I got all the parts I needed.
Scotty, HOPE YOU READ THIS. My AC is already out on my 07 mazdaspeed3. Shop quoted over $2,200!! Saying the compressor clutch is bad. Is that outrageous or what? Should I go to the junkyard and try to find a compressor? Thanks so much man love your vids, Much love from DALLAS TX
Well the junkyard can be an option. But sometimes junk is all there is. You can buy a repairkit for the compressor if its available as an alternative. When you shop for the new compresseor tryshopping for a different brand of compressor that will fit your car. Some brands are cheaper than the oem. Gud luck
Replacing just the clutch isn't all that hard. But get out your multimeter and be sure that the clutch is getting power when the AC should be on first. I assume you've checked the fuse and relay.
The labor is what usually brings the bill up because all of these new cars everything is buried you have to take a lot off of the motor to get to the part.

My AC system makes noise when it turns on. What can it be?
Thanks for your work Scotty! I've learn a lot from you.
Scotty Kilmer what's the strongest car are ever build Ac condition on it
Scotty Kilmer hello me.kilmer , I wanna know how reliable is the ford explorer sport trac & what its best year of production?
Scotty Kilmer ☺
I had to remove half of my lower dash to replace my cabin air filter, I think they should hold car companies accountable for poor design choices
Ano wow 😮, what model car would do you have? Mine is behind the glove box. It takes me 5 minuets to replace the cabin filter.
Jeep renegade
I have to take out the entire fuse box under my glovebox. ST225(XR5)
I would expect that a damn Jeep has an easily replaceable filter, turns out I was wrong
You mean a Fiat-Chrysler "Jeep"? You'd really expect good engineering?
Scotty; that was one of the best descriptions of how air conditioning system works. Most people make it sound a lot more complicated.
Well, with the electronic crap they have in cars now, it can be quite complicated actually. Not in the actual working of how an AC system works, but all the electronic sensors, solenoids, blend door vacuum system or electronic actuated blend doors, all sorts of crap in these new cars to fail, even the controls in the dash fail.

I learn more from your videos about cars then I do reading the books thanks Scotty.
Really? Sounds like bad books. I likes Scotty's book.
wholeNwon yeah I’m more of a visual learner
.... what's a book? 🤔
Dude the timing of this vid was spot on! My AC ain't working well so I'll give your suggestions a try! Thanks.
StrikeFreedom1920 it's mostly low on gas charge.. which will still make you go through all those Scotty mentioned to find out. clean, fix, charge..
I tried it, didn't work.... 100 to renew seals, 80 for Schrader valves, 120 for recharge ....no guarantee....may as well write it off!
this video is all about being cool
Nice
Nice
Nice
.... (even if you’re a geek, a dweeb or awkward with girls)
Yes! Cool by giving knowledge to others and be blessed in returned with gratitude 👏🏼✌🏼👊🏼👍🏼
Who else's air conditioning system is working perfectly but is watching this because they like watching the Scotty Kilmer channel? REV UP YOUR ENGINES!
Collins LFC yup im guilty lol
I don’t even have a car yet 😂😂
Me too !
mine's working fine.. thought that I might have missed out something that Scotty knows.
Collins LFC my AC works great just here to learn everything about cars
This is the way TH-cam should bee. Great, simple, useful.

Rob Lucas no MONEY no AC😂
Man I’m so glad you made this video. My 2006 Dodge Ram hasn’t blown cold air in a few years, and it’s much too expensive to take it in to a shop to get it fixed. They always try to up sell me on crap I know I don’t need. It’s only recently I’ve started getting into working on trucks and cars, so this will certainly be my next project. Thanks Scotty!

Thanks scotty!!
If your AC doesn't work on a German car, throw the entire car away....trust me
S John German Engineer
Damn that expensive?!
S John really? I just bought and replaced an ac compressor coil on my Opel and now the ac works.
S John 😂
That was the advice ("get rid of it") of my own M-B Master Tech with 30 years experience.
My mom's cabin filter hadn't been changed in 10 years! It was a solid black brick of dirt and leaves! She was complaining that the air smelled moldy. LOL
Always been confused by AC, but this video is one more step towards clarity
For those who doesn’t like your channel, they have no idea what type of infos they’re missing on. Your channel is my car life hack.
Thanks again SCOTTY.
who else here because haven't done any of what he says and now has a broken A/C
This just saved me so much time and money!! My a/c was blowing hot air and turns out it was the filter behind my glove department! Thank you!
I usually use AC pro because it has a pressure gauge on the can so you know if you really need refrigerant or not. Also I just prefer AC pro anyway because the cheaper bargain ones don’t work.

Lol. Nice little model airplane engine.
Turn up your AC!
I wonder how many people remember that. :)

He reminds me of Saul Goodman in 20 years time. I love him.
Is your flux capacitor not working efficiently? Here's what you can do to fix it and make those time travel adventures more comfortable. First off, you gotta check it for bugs....
That's because they are always yelling to talk.
He reminds me of Dennis Hopper.
I needed this guy as my college proffessors...,football coaches...fire dept captain....police sgt....principal....cousin...beer buddy etc......I can listen to him all day and understand 🤣
To keep the radiator and condenser clean,,hang a screen such as used for windows to keep bugs out in front of it..
First thing I do when geting new car..
brilliant idea - as long as it does't noticeably restrict air flow. perhaps position not directly on condenser?
the condenser is inside the car and putting a screen in front of the radiator is going to need cleaning too. I guess it could be good in that you can remove the screen to clean it outside of the car.
condenser is outside in front of radiator
Man...this guys ROCKS!

the refrigerant goes into the evaporator via a metering device ( it regulates how much goes in). the refrigerant is in a liquid form into the evaporator where it boils off (like boiling water turns to steam) and absorbs heat around the coils from moving air. it is sucked into the compressor and compressed into high temp high pressure vapor and pushed into the condensing coil (in front of radiator) where it cooled back into a liquid to start all over again..
I have learned so much about cars just by this one video! Maybe now I won’t have to wait on my husband to fix it 😂 Thank you Scotty!
To add to the AC radiator part... Bought my '99 Tahoe in '03 and the AC rad and coolant rad had a lot of bugs, dirt and small stones embedded with a lot of the fins bent. I took a piece of welding wire and bent each end into a different hooking pattern then hammered them flat and taped a piece of vacuum line over the mid section of the wire for a handle grip. I laboriously, over multiple days, picked out all the crud while straightening up the fins as I went. I now have a 1/8th inch square holes screen over the grill which catches the larger materials while allowing air flow. This vehicle also has an add on transmission radiator mounted over the lower right passenger side Ac rad. area which would be extra cooling when trailering.
I never pulled that until last year when I wanted to see what was behind it. To get to the trans radiator requires pulling the grill which was fairly easy to do.

I now have a standard piece of window size screen attached over the trans rad section of the outer screen. I am a fan of using the lye based spray cleaners and a hose for finish up cleaning. The lye is good for dissolving organic matter as well as cleaning in general.
When you remove a valve stem out of a tire, as the air comes out, you will notice the stem gets cold. That is how the AC works also.
Back in the 80s I used to drive for a limo company we had olds mobile 99 s ..200.000 + miles .. us limo drivers used to take a hose.. with a nozzle and spray ( engine off) water from the inside cowl through the radiator toward the outside... Clean out all the dust dirt and bugs that collected in the fins of the radiator... The car is used to run much cooler...
Glad I watched found my cabin filter clogged thanks for the reminder even though I know how the system works
I dont know but everytime I watch your videos, there are moments of uncontrollable laughter, not boring at all. Thanks for this.
Scotty, you can simplify and properly explain anything car related and more. Thanks for your videos!
ac filter …. who knew! Thank you so much - you saved me hundereds of dollars taking this into the shop to get the ac fixed! Cleaned the filter and it works good as new!!
You know he knows what he's talking about when he yells everything he says!📢💨🆒❄️
That air filter got me. I did not seem to be getting much cool air. I did not know what I know now so I had a mechanic look at it.
A good way to tell if you're low on refrigerant is if the compressor keeps cycling off and on, on a warm day with the blower on high.
mine kept doing that when i was running the ac while idling out in 100+ degree wether even when i revved up the engine some so it can spin the fan faster it still did it, and it literally resulted in the ac blowing cold and warm musty air back and forth on my 04 isuzu ascender (gmc envoy)
and turned out by using your car as a cooling station is a good way to harm the engine in the long term
@@fargeeks Yeah probably cutting off on high pressure protection. Possible it is overcharged with freon.
@@billybassman21 i never heard of high pressure protection... must be a thing for modern vehicles and why electrical fans are more suited for the job
Brilliant. What a top bloke. Who says mechanical work has to be boring. Stay safe. From across the pond.
I bought my 2009 Corolla new, the first year a rock hit my windshield and air conditioner condenser. Two separate occasions. I have had the worst luck with condenser all my life. I’m 49 years old, it’d be nice to drive a car that has air conditioner for one time in my life! UGH 😑
Ok, I’m done complaining now.
Save up some money and pay someone to get it fixed it a Corolla anyone can work on it and parts are pretty cheap if we’re talking about aftermarket stuff
@@carljohnson4996 u know what? I still have my Corolla, it’ll be 13 years old in October. I bought the 2009 in 2008. It’s now the best decision I ever made. My kids are driving it now.
I bought a uv dye kit and it worked well. Showed me where my leaks were.
Great info Scotty. I live in Washington and we only get a few months of summer so I hardly use my AC. I have a 95 Toyota Celica and the air conditioner is ice cold I have not done a single thing ever to it. I bought it in 2001
It's called a quality product. Same for my '98 Lexus.
Yup, my 96 corolla's ac went out last year, it was just a bearing in the pulley, but I replaced the whole compressor anyways. It's ice cold again. These Japanese cars were built to last.
'85 Celica here, I regret to inform you my A/C does not work :(
Italian girl
where in Washington?
I live there too
Spokane Washington (State) here.
Scotty your videos should be considered a national Treasure for generations to come…. Thank you for sharing all your life expertise.
Such a "cool" video 😎
Vehicle Virals i see what you did there.well played
Such a funny comment
and I'm such a hot girl XD
Why u here .. did scotty said something bout 335😂
😆😂
Being a auto aircon technician for many years its a intresting trade to have
Real *_Cool_* Car Fix Scotty~
I was told that tip 35yrs ago. My wife and I have the exact same car only one month apart. 5yrs go by my ac is. Like new hers not so much. They both have new batteries and we keep up changing the cabin filter yearly.
Amazing, honest, insightful
This is very healful. I tried 2 fix my AC a couple of times however after the last 2 mechanics told me There was an escape on the evaporation system which will cost me over +$1,000 I decided 2 leave it alone. Funny how when there's cool weather in turn the AC and blows cool air, not cold but cool but when it's hot and I turn it in instantly it blows hot air. My heater works very well and good cause sometimes it gets cold down here in the South.
That banana car kills me every freaking time. xD
The AC Pro system works very well. My AC was cutting out in temperatures above 80 degrees. I had it serviced and unknown to me the shop that serviced my AC added too much refrigerant. The AC Pro system has a V shaped gauge that is adjusted to the outside temperature. It was in the red zone and showed me that I had too much refrigerant in the system. I released enough refrigerant to get the needle to fall into the green zone and my AC works perfect now.
What do you think Scotty?
I tell those with AC to run it for a few minutes during the winter just to make sure the lack of use doesn't damage the system.
I have my ac always on winters and summers. It dries air in winter times so my windows dont fog.
I tell people that to and to run their heater in the summer for about 5-10 minutes just to keep the heater core from clogging.
Not a problem here, summers lasts about 1-2 months
Some do and some don't, depends on the vehicle.
What vehicle do you have that your defroster is electric? Rear window defrosters are usually electric but never seen a windshield defroster that was electric.
Thanks Scotty .AC in my Toyota was playing up. Watched your video, pulled the glove box, pulled the filter out. It had mouse nest in it.Completely ruined. New filter needed. Thanks from Australia. PS the car was parked under a tree often.
I tried to fill my AC up with one of those cheap auto-zone cans of refrigerant when I was younger and broke the compressor, $300 because I didn't know what I was doing lol
What kind of car did you have
Took my car to AAA Auto Repair Center on Tully Rd in San Jose to repair the air conditioning. They told me that the compressor was bad (which I had already figured out since it had a frozen clutch..couldn't push it in by hand while engine was off). I know compressors cost about $300 but they were going to charge me over $1500 to replace it. Then, later, they called me and said they would have to also replace the receiver drier and that would cost another $400 or so. So, after I went back to pick up the car, I looked under the hood and saw a nice shiny new compressor but couldn't see the receiver drier until I got home. Turns out that the receiver drier is like welded to the side of the condenser and has a plug on the bottom that needs to be removed in order to insert a cloth-like cylindrical shaped tampon-looking "drier" that takes moisture out of the system. That's all they did...and they charged me over $1900. The drier "tampon" can be bought at auto stores for from $15 to $35. And the compressor can be bought for about $300. My car is a 2014 Hyundai Tucson. Once you take off the splash panel under engine of the car and look up at the bottom of the "condenser", on the driver's side of the vehicle, you can see and access the "receiver drier" plug to remove to insert the "tampon". I couldn't drain the coolant into a collector before removing those parts so I had to have all this work done by "professionals". Funny, not, how the government will fine you big bucks if you let the coolant escape which helps contribute to global warming but they have no problem sabotaging gas pipelines like the Nordstream pipeline which belched tons of gas into the atmosphere for many days! It's no wonder we are having high, record, temperatures. Wars don't help either. Same thing happened after WWI and WWII..record high temperatures worldwide! Thanks a lot Putin...you son of a b...!!! Putin needs a "b" to the head!!!
Bring back the little glass window in the AC line so we can look for the bubbles or lack there of bubbles.
You can buy them and add them yourself if you have the tools to do it. I did that in my 88 Ford Bronco 2 when I repaired the AC last summer, although those little inspection windows don't really tell you anything of use, other than if you do or don't have any refrigerant. You need a gauge set to actually test an AC unit.
Scotty's Voice Projection High Airflow Self Cooling System is his A/C and he doesn't even need to exhale hot air
Great videos Scotty!
Thanks Scotty for this. My AC is not working and needed to know how I can fix and not break the bank.
When you allow liquid to expand into vapor, stuff gets cold.
I own a 2006 Mazda 6i and it has fewer than 53,000 miles on it that had bought it brand new. Well a few months ago as summer of 2017 was coming to an end, I noticed my A/C wasn't cooling as before. It was also taking a lot longer to cool once it got going. Well two months ago, I bought a can of Freon/collant and a hose, and with the help of a more experienced friend I got the coolant in correctly. The A/C blows cold as hell now on the lowest setting (setting 1)!!! So glad it wasn't a problem with the compressor, that was obvious right off as the compressor would kick on. That can gold got as hell as it was filling the system. haha
Hey Scotty, just yesterday my ventilation motor blower went out. Consequently, I had no air coming out from the cars vents even with the rest of the A/C system working
I accidentally clicked off-topic so I don't know how or why I got here, but thumbs up for your presentation skills
Went to check my cabin air filter on my '08 Jeep and there wasn't one. Guess Chrysler was too cheap to put one in.
Jeep Life71 my jeep it was under wipers.. I had to take the plastic off.. open the hood and take the black plastic off. And it was mounted there on passenger side.. hope it helps with an 08 mine was a 00
Jeep Life71 Same in my 2012 lol. No cabin filter. Had to buy one
My Yaris didn’t have one. I bought a fram fresh breeze one from Walmart for it.
Cabin air filters are often factory options. Seems it was your car’s original owner who was cheap. I had to add the filter to my Grand Cherokee.
What is an air cabin?
My mother's Ford Explorer from 2005 or so (about 13 years old) has always had some pretty awful air conditioning, (due to the design where the vents connected by a leaky duct instead of an air tight duct), so last summer, I suggested she replace the Refrigerant, we got some "AC PRO" from the store and gauge on can said it was in the red labeled "Low", and so I replaced it, and the air was NOTICEABLY colder, and the car would cool down MUCH faster, later on, after I saw my father replace the cabin air filter, I asked if the one in my mothers car had be replaced, and he said something like "No, I don't think it has." *SO NOW, I plan to:* Check if the fans behind the radiator are BOTH working, clean the radiator and condenser, replace/clean the cabin air filter, and run hoses through the ducting so the vents have an air tight connection. THANKS FOR THE TIPS! :)
You get some crazy weather down there in Texas. Hot enough for the ac one minute.then you gotta get your parka on to ring that bell.
This video was really helpful, the way he explains everything is exactly like how teachers try to explain things in all of my online classes :)
Keep it up Scotty !
The only time the hot air in the vehicle is pulled into the cooling system and recirculated is IF that vehicle has that option. Most older vehicles (at least 2001 and earlier) don't have this, so ambient air is cooled and blown into the cabin.
Thank you Scotty. Going to have to watch this video a few more times to fully understand the A/C system. Seems like a lot to take in all at once lol.
The phase change of the refrigerant going from a liquid to a gas takes heat out of the surrounding area, which lowers the temperature of the surrounding area. The gas is then compressed back into a liquid by the compressor, then around we go again. All ac's use this model.
Thanks for making this video. I’ll have my dad watch it so that he can fix my car’s AC 😂🤷🏻♀️
Thank you so much Scotty!
I had a lose connection at the compressor. Cleaned the electric connection with some WD-40 and works well
So my cousin has ac problems and it started yesterday are you reading our lives scotty
F B I I dont know, you're the FBI, you tell me (;
Same thing with home air systems make sure the evaporator coil and condenser fins are clean and the filter is not plugged solid then it should work good
I have two mid-'90's Ford trucks, and neither blows cold air. I am pretty sure they both need more than just recharging....
Han Skinslo maybe new compressors
Probably leaks at the connections, those dang o-rings were prone to failures causing leaks. So the whole system needs taken apart, new o-rings installed, leak tested, and recharged.
I repaired the AC in my 88 Ford Bronco 2 last year for about $500 that included a new compressor, accumulator, o-rings, refrigerant, and the tools needed. About 1/3 the cost of paying a shop to do a 1/2 ass job. Pretty easy to do, time consuming and requires some tools you probably don't have but once you buy the tools you've got them for future needs too. Vacuum pump, AC Manifold gauge set, and refrigerant were the main things I had to buy but I have the tools and some extra refrigerant for future use if needed. So far so good on the AC repair on my Bronco 2. Just needed new o-rings and a new compressor.
+William Todd Wait, wouldn't your 88 need the old type of refrigerant?
Extremely easy to convert it to R134A, just requires swapping out the service ports, vacuuming down the system flushing the system to get all the old R12 out and the old refrigeration oil out and put new oil in compatible with the R134A, then leak testing the system and recharging.
Since mine needed a new compressor flushing the system and replacing the refrigeration oil was even easier, plus I had all the pressure lines out as I replaced all the o-rings, put a new accumulator in and flushed out the condenser and evaporator, put everything back together, tested the system for leaks with the vacuum pump, then simply recharged the system to factory specifications. Took a couple hours start to finish, once I got all the parts I needed.
Han Skinslo I have a 95 f150 and I got my ac unit replaced so I have great ac
Thank you so much! I’m sitting in my burning hot car and have no idea about cars. I am learning so much!
Added my own refrigerant and worked great
Scotty, HOPE YOU READ THIS.
My AC is already out on my 07 mazdaspeed3. Shop quoted over $2,200!! Saying the compressor clutch is bad. Is that outrageous or what?
Should I go to the junkyard and try to find a compressor? Thanks so much man love your vids,
Much love from DALLAS TX
Joe M youll eventually run into the same issue, shop around shops but they go for 900 and up
Well the junkyard can be an option. But sometimes junk is all there is. You can buy a repairkit for the compressor if its available as an alternative. When you shop for the new compresseor tryshopping for a different brand of compressor that will fit your car. Some brands are cheaper than the oem. Gud luck
go to an autoparts store and buy yourself a compressor for your car and replace it. way cheaper than 2k
Replacing just the clutch isn't all that hard. But get out your multimeter and be sure that the clutch is getting power when the AC should be on first. I assume you've checked the fuse and relay.
The labor is what usually brings the bill up because all of these new cars everything is buried you have to take a lot off of the motor to get to the part.
Thanks Scotty! This really saved me from myself. Going to the mechanic before I blow the whole system up
Just open your window and drive fast
Staz Van Bael works for me even with a black car
😂 sure, but that creates drag and the car will use more gas
WolfmanZX 😂 true, just add holes in the back 😂😂🤣
WolfmanZX will use even more gas using AC
Lmao hell yeah brother... 😂😂
I was only wondering about this a few days ago and here you are with the answers. What a legend, thanks Scotty!
The battery has corrosion on the terminal
ncrdisabled Submarine vet clean it
Poor Coca Cola on it and scrub with a wire brush.
This video was so awesome, my 97 expedition's A/C is working better by just clicking the "like" button. Great job Scotty!!!!
I hate summer.
I can never tell if I sweat because it’s hot outside or I sweat because of my sexy hot body.
5-25-18
Sweet, because mines is blowing hot air. I'll go through these steps and come back if I have questions. Thanks!
SkinnyFB you can borrow gauges and pump from AutoZone. Gauges will help you diagnose your problem.
Fixing my AC? Nah i drive 110 mph with my windows open thats fine.
my 98 year old grandma wants to drag race you
SUGAR XYLER sorry that i live in Europe and that i only have 82 Diesel Hp Minivan because that is like that so yeah shut up
Stop eating so many beans and that won't be necessary !!!!!
You must get terrible mpg
T00BR00TAL4YOU na 32mpg is fine
