How Power Windows Work

Here's how automatic power windows work on a car.
The power windows are controlled by a regulator and an electric motor. Window operation depends on the motor's control circuit and the window's position.
In this video, a window regulator from an Infiniti G35 is torn down. The limit switch is comprised of a planetary gear system and tells the window switch CPU when the window has reached its top most position. The encoder tells the CPU the window's speed for jam protection when using the auto-up function. The motor itself is a 12V DC electric motor, which rides on sleeve bearings and has a spiral gear.

That's so nice of him to help his brother remove his window motor. That scratch on the door should buff right out.

Haha He now has a free second window on that door 😉

[@AndrewPerryJr]

Woah! Way more complicated than I thought. In my mind, it was just a simple motor with forward/reverse controlled by the switch and two lever style limit switches (one at the top and one at the bottom of the range).

[@rolandaber5322]

Amazing video! Came up on my feed this evening after spending three days working on my 2002 toyota 4runner driver door window motor and lifter. It was like OMG! I took the motor all apart cause the armature bearing surface at the tip was rusted. Cleaned and lubed everything and got it running again. Having to air freight a good used one from the US to me in Costa Rica jungle. Toyota stopped selling a lot of parts for gen3 4runners, sad. You went a bit deeper in than I needed to get it up and running. Thanks from a very old retired MB auto tech. Cheers!

Many years ago I used this type of motor in a project. They are really powerful and cheap if purchased used. It wasn;t that complicated. Straight drive with the work gear. No encoder or rubber damper.

[@speedkar99]

They sure are powerful because they have alot of resistance to overcome

[@DaveMc13]

After removing the motor from the regulator, you said the motor will spin infinitely (reference: approximately 2:30 in the video). Please double check. I suspect the limit switch is still active and would still stop the motor after a few rotations. I briefly searched the existing 279 comments for similar question without success. GREAT JOB on this video!!! This is the first time I've found the answer to this question I've been wondering for years. I wish there was a way to REALLY LIKE a video.

Wildly complicate. It's amazing that they are as reliable as they usually are. But I'd be happy to go back to cranks.

Exactly. You never have to replace brushes in your arm, or worry about short circuiting your brain. I mean, unless you have a Mr. Canoehead-type incident! LOL

[@robertshirah9486]

Liked & subbed. Quick question,, my passenger window only moves about 3 itches when the switch is pressed then auto-stops,both directions. I tried the rear switch on it and still had the problem. What do you think it is?

[@ZaheerKhan-jt6ve]

What is the purpose of the capacitor across the brushes

[@Tigrou7777]

More complex than expected. Anyway this type of power window looks much better than the one with a wire and rails, which tends to get rusty with time and then broke.
