- Are you amazed at how easily you can raise and lower your car windows by just pressing a button? The mechanism inside your car window is so compact and smart that the window always moves straight and smooth. Also, you might have noticed that you’re not able to move the window even if you try to push it down or pull it up manually. Let’s understand the tricky mechanism that controls your car window.

The worm and gear mech is such absolute genius, especially because it's so simple! I always wondered why the glass stays so solid when pushing down by hand. Amazing.
But if you push it really hard, it is still possible to move the window 😂. I've tried before.
@@ydl6832 yes it can be pushed. Actually, the gear can move the worm. It’s just that the firctional losses are huge. So huge in fact, that for some vehicles, the gear could break before rotating the worm. So don’t do that, you could break your window.
@@vizender Yeah, the glass window or the cable assembly would likely break before the gear does.
@@Milesco also that. I was more in the solid version of that, but the cable is also a point of failure
Stop trying to break in into people' cars
Lesics's videos make you think step-by-step the way the creative engineers think to solve a practical design problem and not just how something works.
yeah, exactly
He should make a video on how a rebreather works
A Dictionary help you find the meaning of a word
That was great. I love learning the engineering behind simple things that most people never think about.
What's always impressive is the mechanical means discovered for these processes. Im sure a lot of hard work goes into engineering a circuit board controlled system but the older mechanical ones are just so beautifully creative
What y'all said!
Helikopter helikopter
Yeah it's amazing to see the work and thinking that went into what is now, sadly, a mostly redundant technology.
I would like to see a similar video demonstrating how electric windows operate. If you have ever had a failure of this mechanism, you will know it's an expensive repair. I am referring to the regulator mechanism.

This is probably one of the best mechanical animations I've ever seen. It breaks down the whole design so you can learn how things developed from start to finish. Thanks for making it!

Love this channel so much! I've always wondered how car windows work. Shoutout to all mechanical engineers of the world!
Thanks bro

Same here :))
As a Civil and mechanical Engineer, I love your videos and demonstrations. Best channel on TH-cam 🙌🏻🙌🏻🙌🏻🙌🏻🙌🏻💙💙
HI❤👌
Best Electic vehicle is are as follows:-
1300 kg
1300 watts
130 kms x2 in 1:1 ratio of rpm 😎
Meaning Tesla range have to be over 13,000 kms in single charge in 1:1 rpm and 24,000 kms and above in single charge with a transmission system with 1:13 rpm ratio mean 1 rpm of motor 13 rpm of wheels in middle level 1:1 in Torque mode 13:1 mean motor 13 rpm wheels 1 😇
Elon musk cars have over 500 to 600 miles range 😏
Change rpm to 1:1 can give us over 9x higher range which is over 4500 to 5400 miles per charge and I m not talking about using and transmission system which easily boosts the range of any Tesla cars over 13,000 to 24,000 miles in single charge 😏
But they r not going to do it cuz it’s very low profitable business and elon musk wants only money money money 😂
That’s y he is not supporting hydrogen cuz it’s even less money money money 🤣(th-cam.com/video/MjlB5VLZ5C0/w-d-xo.html) 😂

Kalki avatar Ironman after 2026 has full control over this matrix code and he is the only one has power of imagination into reality it’s also knows as matrix of leadership This power is beyond the matrix itself with the help of staff of MOULA MUSA a.s. 😎
No one has this power before or going to have in the future 😎
U guys need to cure your eye so that u guys can get control over 8 sridhi (matrix) 😏
Matrix just like cheat code of games aka 8 sridhi 😏
Sridhi is like using quantum energy through electromagnetic particles with the help of quantum codes aka quantum data/knowledge through they Specific vibration and frequency from their words (spells) 😎
8 sridhi/nirvana quantum physics 😏
As a civil and mechanical engineer, I’m left unimpressed.
How civil and mechanical both ?
I changed a window motor and it was directly coupled to to the wire harness. Pretty sure the anti-theft feature is all contained inside the motor box in some designs.
Yes, that's how it looks like in most modern cars. Electric motor has enough "resistance" itself but it is possible to lower the window given enough force (unlike for warm-gear example from video)
I remember the first time changing a window regulator (motor). They sure did put in a lot of time into designing and engineering it.
The driver-side window is more complicated (and far more expensive) to replace than any other window. Because of all the extra controls, electrical equipment, etc.
So a request to all thieves out there - if you're going to break into a car to steal a few bucks worth of parking change then please show some small consideration to the vehicle owner by breaking in through a passenger-side window.
Cake recipe links to you
@@pwnmeisterage I will keep that in mind next time
@@pwnmeisterage ikr , that s why l always lower the windows before parking.
But l still lock the doors because l m not an idiot
@@pwnmeisterage really? It would be a shitty design. I replaced electric window mechanism in one car and it was really simple. The controls are independent from it, all it takes is to unplug a few cables. Why would it be more complicated? Am I missing something?
I hate the newer style of automatic windows. I remember when it was easy - if you want the window open, pull the button toward you and let go when it reaches the point where you want it. If you want the window closed, push the button away and let go when it reaches the point you want. Apparently, some auto engineer somewhere decided that was too simple. So they fixed it such that if you lightly brush against the button, the car assumes you want the window open 100% IMMEDIATELY! If you touch it again, it assumes you want it 100% closed IMMEDIATELY. Why do auto engineers assume nobody ever wants a window only partly opened?
wtf are you talking about 😂
@@DOC_951 apparently more than you can understand.
I’ve got to tell you how incredible was the explanation and the way that the elements were introduced
Congrats for the storytelling, and the visuals
Simple, illustrative, effective, short, to-the-point, high-quality videos that add no excess and waste no time to explain the concepts.
That's what's really great about this channel, and that's why it gets so many views so quickly.
Thank you for being a teaching gift to the world.
The cable and pulley type window lifters in my previous E39 BMW were probably one of the biggest design failures in automotive history. Over than 12 years of ownership I have changed all 4 lifters 8 times in total.
Honestly! As if sliding the window up and down needed to be so efficient because like the pistons go up and down, a car needs it's window to go up and down constantly to reduce drag and increase fuel economy.
thats so weird because my e39 never had it changed even once.
E36 used the scissor design, had to change both passenger and driver side doors 2 times each within 4 years.
It's called a regulator, not a lifter...
Early 2000's audis are the same , chaged out my old s4 avant a hand full of times the worst part is once you get the birds nest of cables untagged and put back in you never really know if the sliders are aligned right till everything is back together🤮
As a kid, turning the old window mechanism makes me feel like I'm operating a cannon or a tank.
No unnecessary intro, no dragging outro, the video starts from zero level and ends at the sophisticated tech in 4mins. Exactly what youtube was made for.
It's so fun to see your prowess at animation improve. It just keeps getting better and better. Also great educational video, I now understand my car's windows!
Fantastic video!
Thank you Jared for the compliments. Your videos are also breaking the internet :)
The God has approved!
Thny
O😊
Superbly instructive video. I have always wondered how the window glass mechanism works, but never bothered to find out. The unnamed design engineers deserve a big round of applause!
I kind of dislike the rope-pulley-mechanism since the rope decided one day to leave the pulley. I had to drive 200km with an open driver side window, luckily it was summer and no rain.
Cool video, I learned so much from it!
Bot. *cake recipe video links.
You really explained it simply loved this video
Another amazing lecture ! Even colleges which we pay thousands of dollars don't able to do this kinda lecture/presentations.
I'm amazed at how she can lower/raise the driver's side window by pressing the passenger power window buttons.
Daily dose of learning. Thank you!
Thank you guys for making it so much easier to understand how these things work and showing the engineering behind it all.
The talk from you just now is really motivating

Amazing. I have a 2001 ford ranger with manual windows. No issues whatsoever. My wife’s 2015 Audi A3. Had to replace her pulley regulator already. Cords got rusted and frayed, crunched up and snapped. I love how some older technology lasts longer due to simplicity.
But even older technology can fail, but they're less likely too. Electric windows are still useful and more convenient as some people can't rotate the crank as fast as other people.
It's not because it's older or because it's simpler, it's because priorities are different now. People who buy new cars don't choose what will last longer, they choose based on mostly appearance.
Nah that's just german engineering for you
Its nice to learn what worm gears really are for.
Brilliant and to-the-point content as always
This body style E Class was one of my first favorite cars. Always loved them.
LESICS bring quite interesting and daily resonating content.
this is a bot.
cake recipe link to you.
Quick, easy to understand, no bs.
Love it
The motor circuit has current sensors able to detect stalling, and therefore stop it when the windows get either to the top or to the bottom.
Some car brands use a simple thermal resistor for the purpose, which show its limit in winter weather, when the motor never seem to be stopping when stalled.
Loved the video. They beautifully explained such complex engineering that goes behind designing the car window with top notch animation
Now I can imagine the working principle of car window while using it. Great stuff 👍
There's also a lot of variations of both of these designs, the scissor version for example actually has a single slider version that's much more centered.
Also the cable pulley version is prone to much higher wear and tear as the cable eventually stretches to the point the winder can no longer wind it properly and the whole system fails and needs replacement.
Such an interesting engineering involved in such common things which we take granted for! Hats off to the engineers👍🏻🙇🏻♂️
Great and clear explanation with step by step !! Great work
Absolutely stunning effort, please keep continuing these great solid works, many thanks!
I have never thought about and really didn't expect that this such complex. Wow!! Thank you for teaching!
I can always count on Lesics to give me some interesting engineering content. A simple subject in a concise video. Thanks for what you do.
I really didn’t know this. Very clever design. Thank you for educating the society you live in. 1 Million People see it and tell it their 2 Friends. Your impact is not to underestimate.
Thank you so much for increasing our knowledge base!
Excellent man! Just loved it! Fabulous!keep it up!!!!!!!
Rope and pulley system is used on many BMWs. The plastic sliders break, necessitating replacement of the whole window regulator. You can swap the motor over, that saves some costs. There is a trick to use zip ties to prevent the steel cable from ripping out of the sliders. I instead just sold the car and bought another Toyota :-)
That's german engineering for you.
Wow !!! such a beautiful animation and explanation. Thank you for taking the time and effort in making this video. Keep the great work going.
Wow I was so sad when this video ended. It was great 👍🏾!
Reminded me of when I had to program an automatic positioning system for the scissor+torque-spring design in my machine dynamics class. These visuals would’ve been helpful!
wowwwww.... everything clear....... i love the way you explain everything....
This simple, easy to understand, video very well explains the technology and costs that goes into building a car (through this simple example).
I like the way you explain. Its Start from basic mechanism movement then to advance mechanism to solve problem arise.
Spiral spring won't control sudden drop of glass.
To control that we need one more spring called torsion spring
god tier animations, great explanation, KEEP UP, THE GOOD WORK! I keep liking :D
Nicely made. Easy to understand the complex engineering elements and solutions.
I learned about this the hard way after having to repair one. 😀
Thanks a million and love you to let me see the world from a different point of view!
*I love such videos. Always great to learn how things work.*
*im just amaze that the window doesn't crack when you try to lower the window in the winter when its all frozen and it tuck so hard trying to pull the window down from the ice.*
Nice illusteration. It now became more easy to understand .
Great video . Thank you so much .I want to incorporate this mechanism for my tv table .
You illustrated the window regulator on my 911 so well, I’m tackling that issue next! (Window came off rail - need new one)
Excellent 👍
I'm glad I know this now! I've wondered how they work for so long!
Your work is really appreciable
Thank you for beautiful simple science clips like this !
Thank you for making this video!
This channel opens my eyes because we give so many simple things for granted
I really enjoyed this and previous explanation videos, I am certain that someday in the far or near future while designing something I will remember something from this video and will get inspired by it.
This channel is on another level. Thank you
This video just enlightened me on why my 2019 Nissan Frontier's manual crank windows crank up and down at a slower pace than my previous older vehicles with hand crank windows.
Thanks a lot for this cool illustrative animation.
I got, surprisingly, highly amused by this video. Love it!
I remember my 83 Buick LeSabre had that device where it had the single arm and remember to this day back in 97 watching my driver's side window fall into my door. Oh the good ol days!
Maybe we could improve the scissor design by adding a ball bearing wheel to where slider and support arm meets. But engineers probably thought of that many years ago, there must be a reason why we don't have it today
Your channel is life saver for engineering students 🙏
Very informative. Thank you!
Nice narration..!! Never thought of this when I casually pressed the button
Excellent explanation.
Thank you 😊
What an interesting topic and a fantastic explanation, thank you very much. Learned this new use of Worm-Gears.
Thanks for giving wonderful info which is used in everyday life
That Worm gear was really brilliant.
Satisfying to watch, thx!
What a great and simple video…enjoyable
Thank you for this incredible animation 🥰🥰
Awesome explaination, thank you
Some good content to watch and learn something new! 👍👍
I've had to lubricate an manual mechanism and it was very interesting. The mechanism actually looks like a battle axe.
Here's what also helps. Spray both window channels with silicon spray., all over the felt. Less load on the electric Window Mechanism.
Nicely explained.
Thanks
Very clearly, thank you.
Amazingly explained !!!
Thanks for the Video and Thank You TH-cam Algorithm for bringing it back to what I love.. learning engineering.
Always educative.... good work, keep it up
2:29 I have a 1965 Mustang and I always noticed that the window would make a "clunk" sound and drop about 1/2" at the very end when rolling it down. Now I know why.
👌👌👌 Very nice and clear explanation. Thank you Lesics. Very much understood.
Thank you, always wondered how it worked
Really impressive your ability to animate anything.
could you please make a video on "How Elevator Works?"
Well that was nice and clear.
It's the first Lesics video I've seen, but I've subscribed on the weight on that alone.
Thanks for the video!
Excellent educational demo presentation. However a key reason for a cable evolution was to avoid hand and head injury if accidentally powered with human body parts conflicting with the glass path.
That was beautiful to watch 👏🏼
I swear our conversations are being listened to, this is what I needed and it's crazy I find it in my YT recommendations.
Thank you for great presentation
I always wondered how a car window works, and now my curiosity has been fulfilled!
