Scotty, I have a 1999 Jeep Grand Cherokee that cool air only blows out the two driver's side vents, but the two on the passenger side only blows out hot air. Can you tell me why? And how much would it cost to fix it? My Jeep is black on black so it's too hot to drive it in the summer so I only use it during the winter months, and I'm forced to drive my second vehicle in the summer.
06 tundra has wonderful air when driving but tapers to nothing when parked and wreaks like must when first fired up. Recommendations?
YOU are an amazing Soul ❣️ Thank You, for sharing knowledge and making it accessable (and easily understood!!).. to All..
✌🏻❤️😎
Are 1976 Datsun 620 good first pickups? I found one for sale (5,000$ cad with 61,000 km) with a couple restomod modifications, but isn’t complete. Is it worth it?
I have a story.
Tried to reverse while on a gravel road with a slight downhill gradient. Wheels spun and broke the a/c compressor. Terrible noise, was gone after changing to a new compressor. The car is a GM make build in 2010, surprises that happened.
An audiologist warned me that driving at highway speeds with your window down will cause hearing loss and I should use an earplug in my left ear, as the driver, if I do so. This was a common problem among older semi truck drivers. So for this reason alone, roll up the windows and use the A/C to save your hearing.
No A/C in my work truck while I was in the field for 20 years. Sounds right, eh. What? What did you say?..
What? I can't hear you with the window rolled down like this. please speak loudly and slowly.
What? I can't hear you.

What's that you say, Captain? Locked out, where's Lassie, oh dear Mr Captain I may have forgotten to feed her . DAMNED senility;. How does Scotty Kilmer always manage to remember everything automotive? It's astounding I say! Just wish I could hear me saying it.
Highway speeds with windows down, aftermarket premium sound system cranked up so I can hear it over wind and road noise. YOLO… and when I’m super old, I won’t want to hear anyone anyway.
One good tip with your car's or any air-conditioning system, is to switch it to fan (i.e. no cooling) mode several minutes before turning it off. That will dry condensation from the evaporator and help prevent mold formation.
This also helps people acclimate to the heat outside so it's less intense when you get out
@@redsunrepublic lol
@@koopaproIts true in hot countrys
Interesting. Never knew that. Thanks for the tip!
Myth Busters did a seg. on "AC on or WINDOWS OPEN", which uses more gas? Their test revealed AC used such a miniscule, piddly amount more gas, than w/ the Windows Open & the tests were SO close, they said " No Difference." They always did pretty comprehensive tests too. Just sayin' & why did they stop making that show? That was one kickass , dynomite show 💣💣💣💣💣💣👍👌
I have found on my car, the calculated Mpg on the dash actually goes up a few tenths of a mile at speeds of 70-75 Mph
I heard they stopped making it because they were running out of good ideas. Also they two stars didn't like each other at all, they only tolerated each other to make the show lol.

Listening to Scotty talk here I’m imagining his hands waving around everywhere. Lol
He would have to have the windows open for that as he's driving down the highway. But with modern AC systems it's okay to keep it on while driving down the highway waving your arms.
quotation marks
TIP: Most car AC compressors reach peak output at 1500 RPM. So if you're stopped in traffic on a hot day after the car has been baking in the sun all day, put it in neutral and rev the engine to 1500 RPM and you'll feel the air out of the vents get noticeably colder.
I usually will just put the windows down for at least 3-5 minutes and use a sun visor. On really hot days it may not make a huge difference but it's good either way also choose the recycling button on the AC as it will cool your car down quicker.
Here is another tip I learned from an A/C friend. When you first get in your hot car and it's 130+ degrees, don't turn the a/c fan to high first-off. Instead use the lowest fan setting so the evaporator has time to cool down for a minute or two*. By turning the fan on high, blowing super-heated air across the evaporator coil is hindering it from cooling down the air passing through.
Also open the windows at least part way for a while so the superhot inside air can escape and exchange with the not as hot air outside.
*(It is sort of like not using a thermostat in your radiator... the water passes through without any restriction or time to remove the heat or giving the engine time to warm up on cold days)
Lets just thank the guy that made that amazing animation

That's ok, I don't mind watching the whole thing, I don't have attention deficit disorder.
So you think the whole point of this video was to tell us to switch the AC on in the winter for 10 mins to wick moisture away from the interior and keep it from seizing up.
Thx
I love the 10-minute videos! Thank you, Scotty, for what you do. I appreciate it!
Scotty misses Houston TX…y’all welcomed back anytime Scotty 🤠❤️
I appreciate that Scotty, you answered a question that has been on my mind lately 👍🏾
Bought a 1995 corolla once turned on the ac it didn't work so i though it had just broken but a few months later when doing an oil change on it I saw that there was no belt on the compressor lol
Oh 😳😳😳😳😳
I bought a '72 Super Beetle which once had A/C-----The old guy took off the compressor to save gas, and gave it away----What a DOPE!!!
How long did it take you for figure out whether or not you had a belt on you pants?
I never turn my AC off even in winter. Never have any AC issues and never have to re-gas it. As the old saying goes "if you don't use it you lose it". Good video Scotty
Good advice, definitely a case of 'use it or lose it'.
So what is it that we're never supposed to do to the car's AC system? I never did hear that!
Don’t worry about it
Come on man
Valid point
I’m old school and I shut off the AC, radio, lights, wipers etc, before I turn the vehicle off. I think it’s a good practice.
Funny thing is I still do too although I believe most modern cars delay all electronics/accessories upon startup so this is redundant. But hey, old habits die hard and it certainly doesn’t hurt.
My wife gets angry if I don't do this while driving her car, since her dad advised her to do this over 30 yrs ago. I googled it and showed her the results, that modern cars automatically shut off all the accessories when you start the car, so it doesnt matter if you leave the ac on.
@@Carl_Aznable yeah it’s along the old school habit of having your car idle for a minute or two before driving off. Where as now 10-30 seconds of oil circulation is good enough providing you’re driving away appropriately.
It's less strain on the battery during startup. Oldschool practice is still good.
@@erikhicks07 it's not less strain because the computer shuts everything else off
With my '89 Jeep Cherokee it made me appreciate my grandmother's '04 Lincoln Town Car, y'all wanna talk luxury car.
My 06 Crown Vic Police interceptor has ice cold A/C as well. Love that thing in the Summer.
Yeah, my ZJ's AC doesn't work. Not fun.
I love those Town Cars.

Best explanation of the AC system in a long time...
I went to AC school for 10 months , Scotty this was the best explanation of how refrigeration works I've ever heard !
A clogged micron cabin filter can also effect the output of your cars AC & Heating systems as well

You have such a great channel Scotty, keep it up. You've helped so many of us save money and it's like we have you as our own honest mechanic. Thank you!
I like to turn off my AC before stopping the car. And let the air circulate ... to prevent musty smell from condensation in the ventilation. Idk if it does anything but I don’t have smells ever
@B Bustin
*BINGO! You should always turn off the AC, LEAVE THE COCKPIT FAN ON, and OPEN THE RECIRCULATE AIR FLAP TO LET FRESH OUTSIDE AIR IN A MINUTE OR TWO BEFORE YOU SHUT OFF YOUR CAR! Leaving the recirculate control OFF allows fresh air to continue to enter the area of the AC evaporator
even after the car is shut off which helps any moisture which can create mold and mildew to dry up instead of sitting in that evaporator!
That musty smell comes from rain getting in with the windows open lmao
EXPLAIN
Oh yeah noticed this from my Challenger. It would be nice if there was a shut down process so the ventilation system doesnt smell moldy socks when you turn it back on again.
@@VintageCars999 Some cars have an automatic system that will allow fresh air to enter the system and the cockpit fan will stay on for a few minutes after the car is shut down.
Watching these Scotty documentaries is like knowing the uncle with all the awesome crazy stories suddenly giving a serious speech one day and he's so formal.
I turned the AC on in my old 2001 Dodge Ram one day. Fan quit blowing and I smelled a burning electronics smell, the AC and heat died that day. RIP you rolling pile of garbage.
So you replaced the under dash fan?
On my 2001 dodge i pulled the whole dash out to replace evaporator core because of a leak also replaced the heater core while i had this dash out. Ive heard that some people just replaced the one that was leaking to much work to do it twice

@@alr1577 🤣
Nothing wrong with it. I actually learned not long ago that when you switch the temperature in your car it's actually mixing Heat AND A/C. It's not actually making your A/C work less or harder if you go to the coldest temperature.
Thank you Scotty.. appreciate you and what you do
I love these "stupid" videos.
"If you're breathing you're stupid!" Lol
The Florida pool pump motor bearing repair guy approved ! that was good info scotty
My AC went out a few months ago. Turned out my heat door actuator failed so I had to take it out and replaced it. Glad I did because its super hot here in Arizona.
Here’s a Top Gear Top Tip: “don’t buy a merc the maintenance is too damn high.”
It usually goes like that for every car, not only Mercedes. If the car was 100.000 USD new, even if you bought it for a nickel, second hand, expect it to be like 100.000 USD car maintenance. Sure, that's not as simple in every situation, but I think its good to think like this.

Lol I had to get my condenser replaced not too long again. Not cheap smh
We did not have AC in our cars as a kid. Driving o long trips was like riding in an oven. Between the heat and air coming into the car windows a 5 to 6 hour drive was hell. You were totally spent. Imagine being in a 100 degree metal box for 6 hours. That was a car trip in 1960's.
Learned that one in HVAC.
You can’t create COOL air you only remove HEAT
Very cool.
So in other words, you can cool down the air, but you can't create cold.
8th grade science: "Cold is the absence of heat."
@@elultimo102 to
@@johnbenzies574 ???
Not surprised it's higher in hybrid vehicles, the heater and the AC really work the battery, and since the car is designed to use that first, then recharge it via braking and the gas motor(and for occasional assistance when you need more power), it burns up the battery charge fast and uses the gas motor more often as a result.
Always always always use your friends car that has good ac when available. My biggest tip. Funny story. I mounted a amp under the dash and drove a screw into the ac line. It’s ok the motor blew not long after. It was blazin that summer of 97 . Never ever ever again did I ever ever ever get near a line again. My dad hit the line while cleaning the ac to a rental home he got in 99. I almost caught him before he hit it, as the Freon poured out, I started sayin $10.00 $20.00 $30.00 $40.00 $50.00 $60.00 and on and on I went as he looked over at me like you smart mouth SOB. He knew he messed up too. I miss those days. Time flies hug your friends and family
Currently for R22 you could count $100, $200, ...
my body always "ran hot" so i always used my ac all year round, even in 3 feet of snow outside. made small talk with a mechanic around 2017-2018 about ac and he explained the overall tech to me and the importance of running it for lubrication. also said the major cause of fridge leaks and other breaks was because of lack of use in the winter due seals and stuff drying out overtime from those couple months without lubrication. So without even knowing it i nurtured my ac and it blows just as cold 21 years later as it did off the showroom floor.
I have a 1987 Ford F 250 custom with a 300, 6 cylinder with no air! Here in Arizona it’s like riding in a blast furnace lol!
Well damn 😯
Uh...hell no!!! 😯🥵😥😓🤢🤮
I used to have a 1978 Chrysler Cordoba with a 5.9 360 and no ac. A blast furnace is a very good description. Oh and this one time after driving for an hour or so I stopped to look under the back end of the car because I heard a noise and mind you the exhaust was cut off directly behind the chrome steel bumper and I decided to put my hand there to look under the car and well when I pulled my hand up my skin stayed behind
Oye! Don't know how you do it in the hot months
Open both vent windows, sliding rear window, and don't stop for ANYTHING lol
You asked for a funny AC story, so here goes..... I once had a car with AC so cold. I dropped my cousin off at work. When she got out some hot, humid air came into the car. When I drove off I noticed "smoke" coming from the vents. I got scared and pulled over thinking something was on fire inside the dash. It was just the cold air mixing with the hot air.
One smells like smoke, the other doesn't.
@@wholeNwon It sure looked like it. Lol
@@wholeNwon - When something looks like smoke, your 0.5 second response *should* be to switch everything off before starting the analysis.
Had same happen in my old Buick LaSabre, back in the day. In fact, the cold air came out sometime with ice crystals.
in super nasty humidity, if i put the window down with the AC on in my Honda Prelude, it would blow snow out of the vents!
one thing I always do when I get into my car in the summer to cool it off quickly is roll the windows down for the first few minutes driving, this blows all the hot air out then I shut the windows and turn on the AC. Also leave the windows or sunroof open a crack while parked and I use a white towel over the steering wheel to keep it from getting too hot!
Yep I do the same, along with using a sun visor and I also will start running the blower motor then cycle the AC when my vehicle reaches operating temp.
I've been a tech for 35+ years and this may be the best explanation of A/C I've ever seen. Better than most factory training classes. Excellent. A/C is taken for granted and with some simple user tips can last for the life of the car. Bravo!
Here is my horror story:
I drove a 98 green suburban for years. One day when I turned the truck off we heard strange knocking in the dash for at least a minute. This has never gone away. When I asked my brother what it was he said is was the little leprechaun people in the dash wanting to get out. I didnt believe him until one day I was playing Riverdance on the stereo and i flicked on the A/C and this confetti paper exploded out of my air vent into my faces and continued for 10 minutes sporadically. I dont know what they want and how they got stuck in there... but I do know they like to throw a party when i put on irish type music... I think it's because the truck is green... hmm
If I can’t find a leak in the AC, I pay a mechanic to put a dye in to find the leak and also to evacuate Freon. I can fix AC compressor and change the lines, but I unfortunately found out that the leak is in the dashboard in my 1999 Durango (it’s my dog car), so it’s not worth fixing it. Too much work disassembling the dash. Yes, Durango is a crappy car but it does have a good V8 Magnum engine so I’ll drive it until engine or transmission go kaput...
One of those rare instances when I'd try a sealer.
@@wholeNwon
I did actually. It did not help. Dashboard leaks are the worst.
But my other Toyotas have never had AC problems: I have also Matrix 2005 and RAV4 2006. Matrix I got free from my mom and Durango free from dad. I got RAV 4 last year that I bought.
@@igorseprak6177 Which product did you use?
@@wholeNwon
Regular Auto Zone AC seal leak. In this case, mechanics actually saved me money by finding the leak with purple dye where it’s hard to trace. $100 well spent it turns out. Had I not done the dye, I would have been sucked in the the AC quicksand by changing all the parts but disregarding the dashboard.
@@igorseprak6177 Actually it's the second or third place to look. If you used a rubber seal conditioner as a leak stopper that wasn't bad but, since it didn't work, I'd try an actual leak sealer. Of course, if I had any plans to salvage the system, I would not use one of those products.
Went to Vegas this early July, and the a/c on My friend's RAV4 didn't work at all... It just kept blowing hot waves. We had to get some ice bags in the car to cool the cabin😂😂😂
Change the cabin air filter once a year (or as often as it says in your manual). It keeps the HVAC from getting strained, keeps it performing well, keep allergies at bay, and prevents a nasty vinegar smell from the vents.
It's best to simply run your AC all of the time. The big benefit here is you are constantly drying the interior out so it doesn't get that wet dog smell, or cause rust, and it keeps the AC in good shape, for hundreds of thousands of miles, and the gas mileage hit is negligible.
I bought a car 3 weeks and 350 miles ago and the entire AC system had crap in it, so I paid 1834 USD to replace the compressor, condenser, and expansion valve. That's my horror story. The car has about 29k miles on it. Oh and I'm currently looking for a new engine (crazy rod knock). Will not buy from that used dealer again.
buy a 2017 Mazda CX 3 Touring awd automatic 4 door if U can find one ...make sure it's awd for snow belt areas....(don't buy red)....no problem at all change the oil at 4,500 miles or less NOT 5,000 miles like the book says....we have Mazda 2002 Protege Lx automatic FWD 4 door have 200,000 + miles no engine problems whatsoever... we just change the oil religiously every 3,000 miles ....sometimes B4.... 3K miles... we always had a Mazda Protege at least we leased them B4 & also no problems...(follow changing the fluids etc like Scotty says if U plan on keeping the car "forever"......(past 30K ....50K miles...change fluids etc)
I had a mouse fall into the AC barrel fan of my 2002 Chevy Silverado. It threw the balance out and made a terrific rattle. I pulled the fan out, got rid of the mouse and reinstalled everything and it worked fine. Tho the mouse didn't survive the G-forces. DOA.
My wife's 2007 Honda Accord A/C crapped out on a long trip - it turned out to be a relay under the hood - after I researched the problem, I discovered this is a very common issue with Honda cars - so I now keep a spare relay in the glove box, for when we go on long trips in the summer time.
One thing I remember was that one way to know if the refrigerant was low or there was a problem was if the compressor turned on and shut off in rapid succession. Not sure if that’s still the case nowadays?
I think true. The pressure switch is sensing that lower press and turning off compressor.
Too high or too low will give the same issue. Improper air gap will also give you that problem.
I told you my dad owned Baskett's Texaco. In late 50s, he and Fred Jones, who never cashed a paycheck from my dad in 30 years, began installing FridgiKing air conditioners in cars including some brand new cars. It mounted under the middle section of dash was about 20" depth by 28" width by 7" height. All vents and controls were on the unit and the rest was under the hood, although I think there was a small component under the dash also. They had to custom fit each unit and the one in dad's 54 Mercury cooled the backseat just fine as I rode back there. It was so cold and we loved it. It caused dad to put extra help on to pump gas and do tire and oil changes. He and Fred were popular for several years until advances changed the way it was done. Boy if you saw a picture of Fred, you would swear it was old Honest Abe. He was a very private person.
I just wanted to show that they were installed well before the late 60s early 70s.
Love your show Scotty...
People in Southern AZ, use their A/C in the city with no regard for the speed. It’s thrashing hot 🥵
I try to minimize usage of AC unless its a real hot day. I can see the RPM's go down slightly when it turns on knowing it's taking power from the engine and using more gasoline. At $4 per gallon here in California every drop counts
I used to have an old Honda Accord the AC compressor didn't have freon gas at all and in the winter and fall season my windshield used to get foggy as hell. Once the compresor had freon gas in it, windshield didn't get foggy on a rainy day..
I recently had my condenser and evaporator replaced by Honda in my 17 civic. No cold air was blowing when I turned the AC on. Replacing both parts cost my just under $1300. Honda warranty covered the condenser. They had to take the cabin apart to get the job done. My service rep was nice enough to throw a discount too. AC is nice and cold now!
When the outside temperature is over 110 degrees (F), my AC system stops working.
Possibly your ambient temp sensor. The ac and computer relys on this sensor to trigger the ac compressor to kick in
Are you RODDNEY DANGERFIELD/
I have a 2012 chevy sonic. Was quoted by the dealership that a/c compressor needed to be replaced. Started to have a/c temp heat up at stop lights and got cool again after taking off from stop. Took car to local high school automotive class. Found out all I needed was a new radiator fan and connector harness. $150 compared to $1400.
I repaired my air conditioner in my 1999 Ford Ranger after watching your videos. Great content in this video, even for those of us who studied thermodynamics!
I started driving in the early 70's, I remember my parents MASSIVE, 1971 Chevy Kingswood Estate station wagon, seated 9 people! If you tried starting it with the AC on it would put a heavy load on the start system because of the turning the compressor during the start cycle, sounded like a low battery, turn off AC and engine cranked normally..Now a days doesn't matter, like Scotty said it's disabled until the engine starts. Another myth I've heard is its harmful to run your system to run in Max AC all the time! Don't know if this is true or not, my AC is always on, unless I have the windows down, generally I just regulate temperature and leave the system always on. I haven't had any issues so far and I have been doing this for years. I enjoyed that car, was very smooth on the highways, 3 bench seats but the nice part was the 3rd rear seat folded into the floor so you had a nice cargo space if you only needed the first two bench seats. Thats still seating for 6..
And we also had to top off the water in the batteries.
Over here in California, we have a Highway here that passes over a mountain called “The Grapevine”. Just before the incline, there’s a big warning signs that tells motorists, “Avoid overheating, turn off your air conditioning”. My girlfriend and her family would be sweating in the heat because they obeyed the sign.
I remember that stretch! Luckily always had a vehicle that could that take "steeper and longer than it looks" stretch with the a/c on.
I miss the wing glasses on the doors of older cars and trucks. You could roll up the window and still get air directed at you when opened.
The boiling point (temperature) of automotive refrigerants is between -12⁰F and -22⁰F, not 32⁰F.
Yeah that's under atmospheric pressure. A/C systems aren't under atmospheric pressure. They are routinely at 275 psi/1896kpa. Which raises the boiling point by a lot. The opposite can be said if it were under vacuum.
@@pimpustthugni: After the refrigerant passes through the TEV or the orifice tube, where it is "atomized" and goes through a phase change in the evaporator, it is no longer at high pressure.
Bring me thy pizza.
You mean freezing point???
As a kid, I went on family vacations all over the deep south in a 1960 AMC Rambler station wagon. No A/C. Windows down and loving it!
We did that too, in a Ford station wagon. When we went to the Southwest, we had air cooled canvas water bags hanging from the side mirrors.
You mean before climate change started increasing heat everywhere at recording breaking paces?
@@PhaseSkater Actually, global warming began after large scale factories started burning coal and polluting the atmosphere. The earth was cooling because of some major volcanic eruptions in the late 18th and early 19th century, but started warming sometime around 1830. We just didn't notice it until the 1950's.
@@jimichan7649 it's called the sun that causes the heat, first they called it global warming then they started calling it climate change which is true because the climate has always and will always change hot or cold on the earth but politicians will always make it sound like it's are fault to raise money and taxes.
@@idratherbefishing7753 Ever heard of the greenhouse effect? You should look up The Great Stink and The Great Smog.
4:25 In the early days, people didn't have air conditioning in their bulldozers...
1994 Suzuki Sidekick has dealer installed air. Parts are IMPOSSIBLE to find. So we decided to switch to a factory A/C setup. Condenser, electric push fan, filter/drier (with a pressure switch), compressor, evaporator and expansion valve. The system also had an evaporator temperature switch (mounted on the airbox to the evaporator with a thin metal probe). Going through the wiring and hook up of everything now. Not sure how the (as Suzuki calls it the dual function high/low switch on the filter drier will work but) we will see.
My a/c starts and warm air comes out, that's all.Mechanics say that the compressor may be bad or locked. Apparently the freon stays in but no cold air. Could it be the expansion valve or the compressor? Help.
Any Mechanic should check the pressures before saying anything, unless the compressor isn't engaging, then it's an electrical diagnosis.
My dad used to Have a 1987 Ford Tempo GL while mom had a 1987 Oldsmobile Ninety Eight Regency. 2 years after dad bought the Ford Tempo new, during a 110° day the compressor clutch failed. He was not happy! So while the car was scheduled to be repaired because the shop was busy he had to borrow Mom’s Olds during the intense heat.
Also it has 231000 miles on it and when its running it still sounds and shifts like new
Yes. I have a 2002 Honda Accord that still have the original ac unit I use it all the time summer or winter. Works excellent
My 28 year old Altima still blows colds air to this day ‼️ long live R12‼️
ford and chrysler were the dying of R12. bad connections and hoses !
@@poolmotorrepairguyFL Hoses. Definitely not good for an A/C system.
Not many vehicles still have R12 . I'm guessing if available it's at least $300 a litre or lb or something.
Altima’s never had R12. Their first year, 1993, had R134. The car’s predecessor, the Stanza, had R12.
He has a lot of knowledge and is a good teacher. There’s a lot of people with a lot of knowledge but many of them don’t know how to explain it well.
I like to roll up the Wool-o and get all schmoked up while watching the Scotty Kilmers videos
Spark it up, young man! Spark it up.
I just had the rear a/c evaporator replaced in my 2013 GMC Acadia because it was leaking. It has 85,000 miles on it and it was the first repair that I’ve ever had to fix. It cost me $1100 for parts, labor and sales tax. I had it fixed because it has been a reliable, comfortable AWD SUV that goes really well in the snow. I hope it stays maintenance free for another 85,000 miles.
This has been my favorite video ever. Can you do more of these with other car parts? I feel like you explained the process of AC in such an informative way that I actually understand the functions of the entire system!
I was working for Advanced Auto Parts when a customer comes in saying their AC isn’t working, “all right let’s go see that the problem is” I said. I put a gauge on the system and it was basically on the verge of exploding due to so much pressure being in the system. The moment that gauge went on it pegged the needle at max pressure. So I asked the customer what was going on here? Now for the life of me I can’t remember what they said but I instantly recommended that they see the mechanics to recover all this extra refrigerant and have the system balanced or recharged.
Hey Professor Kilmer,stay "cool" and enjoy your weekend. 😎🙏✌
I had a next door neighbor once, Like scotty!, that could fix almost anything except open heart surgery, he was never out of work! If your neighbor is like that, treat him like "GOLD".
What years are considered a “modern car”?
I would assume 1996 onwards
Usually cars with electronic fuel injection
I bought a 2006 chevy impala brand new when it came out. It did great for awhile but then all the gremlins start coming out around 2012. First i had the water pump break on me, so i got that fixed right away. Then i had the blend door actuators going bad and making constant ticking noise. It was a cheap part but can be difficult to replace. I had the dealer replace one deep in the dash and it was $700. 11 months later, it happened again, luckily it was the one the dealer fixed and they replaced it under the 1 year warranty. Then i had another blend door actuator under my glove compartment. This one i just left alone because it only started ticking when i turned off the air recirculation or turned off the car. It wasn't doing any harm. Then my a/c compressor broke. I took it to a shop on the military installation and they told me to take it out in town to a mechanic, get a diagnositc and bring it back. The mechanic said the compressor was shot and would cost $1800 to replace. I took it back to the shop on base and they quoted me $1300 and that included replacing the whole a/c system, not just the compressor. Plus i didn't have to pay sales tax. A/c ran strong since then. Then my water pump broke again about 6 years later. And then i had another blend door actuator ticking on me but it wasn't an every day issue, just when it felt like it. At 124k miiles i decided to trade in. Everything else has always been good with the car, the motor ran strong did regular oil changes with synthetic oil, never had an issue. But never again will i buy a new design model in the first year. I got a decent deal for trade in, i was expect $1600 because it was in fair condition but they gave $3000 and i used it towards a new truck.
I didn’t forget to spank that like button Appreciate y’all Scotty all day long. Yahoo
Scotty, your videos should be mandatory viewing in every high school in the country!!! You are the Dude!!!
I love it when I can get a “Like” in soon enough on Scotty’s videos to actually see a change in the running tally. 😊
My pawpaw was the first person in Port Arthur, TX to have a/c in his car it was a Cadillac which he always had a Cadillac. He retired from Texaco refinery after 35 years & ended up as one of the head supervisors for the plant. He started an a/c installation & repair business after he retired which was a year before I was born. I grew up helping him & my uncle doing a/c jobs.
Newer BMW’s, Merc’s and other European brands that are either all electric or Hybrid-electric now use R1234yf as the refrigerant - its a flammable gas/liquid!!! How does any manufacturer get away with this choice???
Some bootleg shops would use LP gas as refrigerant. Illegal to do. They did it because it was cheap.
My shop deals with leaking evap cores and broken compressors a lot. The most common reason..driving with the ac on with the windows down, and/or not putting it on recirculation mode.
At what point where does the water weep from to drip from engine or passenger compartment?
Living in the middle east, the weather here is always hot. I always use the A/C its a must here.
2014 forester, inconsistent temperature. Ac will be cold for 10 min, then just blow regular air. Took to mechanic and he couldn’t recreate the problem after 2 hours of blowing ice cold 🤦♂️ why does my car hate me
It is normal for Subaru
According to Scottie, it could be low on refrigerant!
AC clutch may be going out
i had a 2002 buick lesabre, and when i bought it, no matter if i put it on hot or cold, the 2 vents on the drivers side always blew hot air. I was told theres some kind of a flap or valve or something that is preventing the cool air from coming out on that side. even with the AC off it oozed hot air, so i had to keep the vents closed, and that made the dash get hot a lot... thank god i drove that car till nearly 200k miles with few other issues for a long time, and scrapped it when i bought my new Subaru
The AC in my 2019 Camry is so cold that I was actually turning it down when I was driving through Arizona in 116 degree heat 😆
Toyota does make great A/C's for sure
On my toyota Corolla, 1.6L, 2006, I apparently had a hole somewhere in my condensor. It cost me around 500 dollars (5000 converted to Swedish Kronor) to fix that at my local, non toyota auto repair shop. So yea, it aint cheap, but oh so worth it in the end.
Had I let my local toyota dealership fix it, they probably would have charged med around 600 to 800 dollars. And I also think they somehow would have screwed it up.
I love these, makes learning easy! ❤️
I remember when not all auto manufacturers offered A/C as an OPTION. If you wanted A/C you had to buy an aftermarket unit and hang it under your dash. It was better than nothing . . . Mostly.
When it is Hot and Humid, I don't care how much extra gas it takes, I want to be Cool, plus I can't breathe good in Hot Humid Air.
My a/c system hasn't worked in 3 years, it doesn't get cold. I was told the compressor needed to be replaced, can't afford to replace it so I've suffered for 3 summer's worth of heat.
I've had snow come out of my air conditioner before lol
What’s nice about hybrids and EVs is the AC is connected to battery versus the engine so it’s crisp and cold the moment it turns on
The disadvantage with a hybrid is in heavy traffic on a hot day you can watch the battery level drop quickly and then the engine will turn on to recharge the battery. Watch your MPG drop. Similar with range on an EV.
