How Windshield Wipers Work

- Here's how the windshield wipers work to clean the front window on your car.
The windshield wipers move in a repetitive translation sweeping motion across the windshield. This motion comes from a motor, that rotates. Using a crank slider (push pull rod) in addition to a four bar linkage, the repetitive sweeping motion is achieved from the wiper motor.
The wiper motor assembly consists of a spiral gear that engages the drive gear. This prevents the wipers from being forced down by hand. This also provides torque multiplication and speed reduction.
On the back of the drive gear is 3 contacts with a break in it at the home position. When the break lines up, the position of the gear indicates The park position of the wipers, breaks the drive circuit, and thus the motor knows when to come to a stop.
The wiper switch contains all of the electronics for the intermittent function. The motor itself has a resistor for built in hi and low speed control.
A steel wiper blade consists of small linkages that attach the frame to the blade. This helps to distribute pressure across its surface and is called a whippletree mechanism.
Finally, the washer tank, consists of the level sensor and pump. The level sensor is a reed switch, simply a magnetic switch that turns on when the float drops below a certain level to turn on the warning light on the dash board. The pump is a tiny DC electric motor with a small impeller to provide fluid flow from the tank out to the nozzles.
Automatic rain sensing wipers use an infrared sensor on the inside of the top of the windshield to sense rain droplets through reflection. A computerized system then activates the windshield wipers accordingly to keep the windshield clear.
The wiper and washer system in this video was demonstrated in a 2001 Toyota Corolla. - Auta a dopravní prostředky
No bla bla for hours. Clear, efficient...
You taught me something without wasting my time.
Thank you !
Yeah that's my style, short and to the point
I fully agree. I can't stand those presentations that begin with a ten minute introduction of what the video will be about and the ten minutes of excuses that the camera and the 🎉sound are lousy. "I'm going to show you how to change a spark plug. My great grandfather built this shop in 1896..."
Exactly what I like. Rapid explanation with no music and no extraneous bullshit.
That's my style. Short and to the point
Oh man, I was good till the brothers underwear, I'm dying here 😆
Gotta use what I can for greasy situations
I like how this guy does his presentation with his videos but just wanted to clarify a few things: the motor is an electric motor - not "electronic" / the spiral gear is commonly referred to as a worm gear / the switching mechanism behind the rotating spur gear (driven by the worm gear) is mechanical in nature - not "electronic". The term electronic seems to be ever more loosely used in describing components such as this when electrical is much more appropriate. I came here to learn how windshield wiper system work as I have an issue with my car's system not returning the wiper blades to home position when turned off. I thank this gentleman very much for taking the time to assemble this video! I think he also produced a video on EVAP systems used in cars as well, which he also did an excellent job of-thanks!!!
Well constructed video. Very clear,concise and understandable. Presentation and communication excellent.
+A Bloke thanks!!
Wow very detailed!! Well done. You are a true genius.
+Paul Wehbe thanks, glad you appreciate it
Paul Wehbe thanks so much
There is an entire universe behind that switch lever.. gosh !! Im going appreciate those wipers work every time when i switch them onn !!
Wow, an intelligent and knowledgeable discussion about the internal workings of the windshield wiper motor and associated transmission. Most videos just show how to take the old motor out and put a new one in without explaining the internal workings of the 12V motor and electronics in the transmission housing. Thanks again for the great video!
Thanks...I love diving in and seeing how things work
Yay! Your brother got a new toothbrush!
+ardhunaan He sure did...except that was the toothbrush from 2 videos ago haha
And a new underwear too... 3:16
ardhunaan probably stole his wifes one 😂😂 jks
This was an A+ video. Thank you! Down-to-earth, knowledgeable, the jump cuts add pace and comedic relief!
You are welcome!
Thanks for this. I'm attempting to build a cat toy launcher for my pet and I think this motor will be the best one to use. I needed the detailed explanation without having to take the motor apart.
Thanks ...check my Honda wiper video too for more ideas
If you can explain every detail and functions in a very short time and easily understood, you have a very deep knowledge of what you are saying.
My goodness, well done! That was an extremely well made and thorough video! 👍🏼
Nothing like a clean wipe.
+Hugh Jafro haha good one
Excellent!
Two things I enjoyed:
pointing to everything with a suspiciously clean toothbrush
using your _brother's old underpants_
Now I'm going to watch this a few more times to understand the satisfyingly complex system, Heath Robinson would approve.
This was great! Thanks for doing a video on this, I've been looking for some time on a detailed video covering how the windshield system works. Seems like no one has ever taken the time to do one until now. Thanks again!
+B S glad you found it helpful. Thanks
Many mid-20th century cars had a wiper motor powered off the engine vacuum. When the accelerator pedal was depressed (such as when driving uphill) the lower vacuum of the engine would often cause the wipers to stop working.
Interesting
Impressive! Windshield wipers crash course in 6.40 min ! Congrats and like !
That's my style. Thanks
Thank you for such a detailed and complete description of the whole mechanism! I truly enjoyed your video.
+maximpulse Awesome! Feel free to check out my other videos for more!
Oh boy this guy is a master!
I actually enjoyed this, very in depth great job man
+xxroyalxtigerxx thanks, I'm glad you learned something
I always wondered how they knew to "park" when done and go down to a lower spot than they had been when wiping!! LOVE you channel.
Wow.brief fast yet so understanding. He knows all the mechanics and the electricals too🤩
Thanks. I try to be all encompassing
Thanks, now that I know how the park position functions internally I can diagnose better. Appreciate this video. Great work
Awesome thanks
One of the most efficient explanations in the Universe!
This was insanely helpful for learning about crank and rocker four bar mechanisms. Thank you so much.
Welcome
This man is a professional at work
Perfect video, succinct, and informative.
I was looking for something else. However, this video is useful, short, and to the point. Thanks for sharing
Glad it helped. What were you looking for?
this man really knows what he is doing!
good job
Thanks!
My TOYOTA Corolla 97 wiper model. Exactly what I was looking for. Thank you.
Yep this was an 01
Another great video. This time, I didn't come looking for help for my car, rather someone was using these motors for their robot build and I wanted to know more about how they worked.
Late, I know but great explanation and video, thanks.
It's never late if this helps!
This is so wonderful. Thank you
Awesome detail! Thanks for sharing.
THANK YOU VERY MUCH! Its a big help to me. Keep putting up great fixes. 👍🙏🍀

Always great, great detail and insight!
+chris hill thank you glad you enjoyed it
So educational! Thanks for this!
+MrWip3out glad you learned from it
Excellent video. Well Done.
Great stuff, I always wondered how everything is working underneath the cowl.
+mrjost55 thanks. It is a bit different for every car, honestly the corolla has the flimsiest if seen.
But toyota says their cars are cheapest to maintain lol
Great video!
great video thank you man for making
Welcome
Your Videos are the best. Thank you for being detailed. Your are a true educator.
LOL! You are a true educator.
Cool, I always guessed it was a push-button limit switch external to the motor that got the wipers to "park" at the bottom, but it's more like a rotary switch internal to the motor.
Yes it is a rotary switch, and the contact breaks at the park position
Really nice . made it easy
LOVE your ball-joint removal tool at 0:43! LMAO
+asdflkjh me too thanks!
Thank you very muchj sir for the detailed explanation. I always wondered how wipers work. You got a new subscriber. Keep up the good work.
+Faizan ali siddiqui Mohammed thanks for subscribing
Very well explained ! Thanks
+ea6dx Windshield wipers are complex eh
Thank you so much, you're awesome.
Again here I found what I was seeking, I couldn't find it elsewhere.
That bit about brother underwear 🤣
Awesome video. Perfect. Exactly what I always wondered and needed to know in my current problem. Trying to fix a Ford Truck. They have the wiper motor going threw the GEM (Generic Electronic Module). I was hoping to wire around the GEM with the use of a High/Low switch. Between the wiring diagram and your video I now have a much better understanding on how I will do this. Who knows maybe I'll make a video of my fix. I've had to fix other things on that Truck. Thank you.
Glad you found it helpful
Explained very well.
Your videos continue to be amazing!!!
+dougdevine27 thanks
Nice explanation

Dude, awesome video. That was so informative!
Thanks!
This is the work that deserves subscription w/o being begged for that ... subscribed 👍
I like your teach , me from Cambodia 🙏🙏🙏
Hi , it's a great video. I manage to understand how it works now. Just found an error at 6:01, you mentioned capacitor. BTW that's a transistor. There are capacitors in the circuit. Well done for the effort of making this video.
+Vijaya Gopalan Subramaniam thanks for the correction
Very informative and oddly entertaining video. Will be coming back for more. (This video was featured on popular mechanics and that's how I found out about your channel)
+patriotbarrow thanks
Stay tuned for more like this
I love this channel.
I wish I was good like you. I've made 3 videos but your videos are great.
+Martin Evan thanks, glad you appreciate my work
Brilliant video

Next I'm going to type in my comments 😋 great explanation
Next I'm going to reply you
3.20 loool brothers old under wear sure they wernt youres lol, so far this is the most helpful whipper motor video on you tube ,
Thanks and that's great to know
GREAT great video man!
Wow! That’s a lot of information in a very short time! Terrific explanation! It would not hurt, and would help many viewers, to go just a little slower. Keep up the good work. Best wishes.
Thanks I'm glad you appreciate my work
Outstanding video. You should be teaching mechanical engineering classes. Way better than my over-educated professors.
I wish I could become a teacher one day...
@@speedkar99 you should pursue it then, you have a talent for explaining this sort of thing in a technically correct but condensed style. Most engineering professors are useless and don't care about the students because they are too busy with their own research.
Quite helpful 👍🏽👍🏽
right to the point like I like it. subscribed.
Thank you for subscribing
Just discovered your channel and I love it! Both me and my father have subscribed!

Glad you appreciate it
Amazingly amazing video. Superb explanation. You gained a subscriber at first sight sir!
Excellent information video sir 👍 👍 👍
Thx bro!
Great simple
Nice Job!
Thanks
The day you made a youtube video .... your brother knows he is gona need a new tooth brush and a new underwear..😀 ... nice videos Bro... really impressed by your way of explaining complicated stuff in easy to digest way for dummies like me... really appreciate it... thanx again and keep it up.....
+Muhammad Tayyab thanks, short, to the point and easy to understand is my style.
My brother doesn't use underwear and toothbrush so he's not missing out on anything.
exelent!! thanks!!!
