How a Sunroof Works

Here's how the sunroof/moonroof mechanism works to allow sunlight into your car's interior.
The sunroof is a body colored metal panel on the car's roof that tilts. A moonroof is a transparent window located on a car's roof that tilts and retracts into the car's body. It allows the entry of light into the cabin, an open air feeling when retracted and the ventilation of air when tilted.
The sunroof/moonroof is comprised of the tracks, water channels and tubes, an electric motor with a gear train, spiral cables and a 3-bar linkage that allows the sliding and tilting of the roof into the car's body.
This video shows the process of removing the headliner to access the sunroof and the full disassembly of each component to see what's inside and how it works. Vehicles with failed, broken, leaky or stuck sunroofs require a similar amount of work to be performed to access failed components, often with exorbitant labor costs due to the way it is compactly packaged.
The vehicle in this video was a 2004 Infiniti G35 sedan.

speedkar99 my sunroof won’t close it is fully open but it seems like the sunroof window is further in then the other side. The open and close button does not work but the tilt does. The window is stuck on the open position. Hope you can help thanks.

[@asamann1738]

@@josegarcia-vs9hp I have this exact problem. Just mine is stuck shut. The buttons word fine but the roof is all bent or sum. It only moves about half and inch before stopping. You could just remove the window. I’m thinking about doing that.

VERY NICE VIDEO.....AND THIS IS THE ONLY VIDEO I FOUND ON ABOUT SUNROOF WORKING MECHANISM TILL NOW 👍👍👍👍👍👍👍👍👍

[@fafb9441]

I opened our sun roof for the first time this year. When I tried to close it stopped and reversed to the fully open position. I eventually closed it by pressing the switch momentarily at 1/2 second intervals until it returned to the closed position. Good thing it didn't start to rain. I will look at it again on the next sunny day. When we bought this previously owned vehicule they sold us a service contract that would pay for any major repairs. The roof has been problematic since we got it. We asked for an estimate but the insurance company would not pay for it because it required the remplacement of the tracks which they considered a wear and tear thing like brakes. I thought it could be some sort of sensor or cpu/logic thing. We have a Jeep Renegade 2015.Thanks for the video. It's good to know the components and mechanics that are involved. I'll try that reset thing.

This is a fantastic video. I really appreciate you going through all the effort to explain this whole mechanism in such a clear and concise way to make it very easy to understand. Great job. I do have one question that wasnt entirely clear. If somehow, the 2 cables become out of sync, not allowing your sunroof to close properly, (glass twisted) how does one go about getting it sit in its proper placement to function properly. Do you remove the gear on the motor that moves both sides, postion the glass manually and return the gear?
