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.

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.

@WaywardPondering 3 года назад

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.

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.

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.

@VintageCars999 3 года назад

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.

@watershed44 3 года назад

@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!

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 remember the old 74 Plymouth Valiant (Dart) used to blow frost when you turned the air on. It could/would freez you out in the middle of summer. Back when cars were simple. Wish I had that car today.

When the outside temperature is over 110 degrees (F), my AC system stops working.

@garrettdlouhy5531 3 года назад

Possibly your ambient temp sensor. The ac and computer relys on this sensor to trigger the ac compressor to kick in

@Anthony-fd8mh 3 года назад

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?

@whereisthehook 2 года назад

I think true. The pressure switch is sensing that lower press and turning off compressor.

@user-qy9rg3nt2l 2 года назад

Too high or too low will give the same issue. Improper air gap will also give you that problem.

@christmaschris487 Год назад

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 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.

@florinlepadatu5648 3 года назад

Great video! I own an e39 for 14years (produced in late 2000) and the AC system worked without any major issues, I had 5years ago a cracked pipe and 2 years ago a funny thing happened, if I drove the car up to 120-130km/h the AC worked fine but as soon as I went higher a strange noise coming from the engine bay and AC dies, if I reduce the speed below 100Km/h and restart the system, AC worked again. When I opened the hood, a clutch smell is coming from compresor pulley so I replaced the compresor clutch but no, this was not the issue, some valve inside the compresor was faulty, get stuck at some point and lock the compresor causing damage to the clutch. I replaced the compresor with a used one under 30eur (a new one is about 500eur). why is so cheap at junkyard? because on e39 they rarely brake. So even if I refreshed the freon and compresor oil every 2-3 years, after 300k km it is expected something to go wrong but I have friends with new cars, premium german cars that have issues with AC system at 15k km, 40k km and as soon as the warranty expires around 100k the compresor is falling again and this is something that should never be expected of a new car. They changed the system, I guess was too reliable...

At what point where does the water weep from to drip from engine or passenger compartment?

@robdixson196 3 года назад

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.

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.

@adamdahlin6025 2 года назад

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.

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

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.

My ac is always on, no madder weather :) I had a brand new Hyundai I30CW, and always used the AC for 3 years, and in some of the Services Hyundai did, they checked my AC, they was very impressed by it. They said you AC work extremely good.
