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.

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 2 жыл бұрын

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.

@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!

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!

@VintageCars999 2 жыл бұрын

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.

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...

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

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.

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.

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

@robdixson196 2 жыл бұрын

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.

@adamdahlin6025 2 жыл бұрын

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.
