Infiniti G37 sedan sunroof glass replacement
This little project is actually way easier than I thought it would be. If your glass top on sunroof got damaged, you can easily replace it. I will show you how to do this and get it done in under one hour. I did the replacement on sedan model, but I am sure coupe models installation will be identical.
First question is where to get the glass top. I got mine off ebay for about $150. I heard that the go in junk yards for $100-$200. On ebay, you can see its condition, in junk yards, you would have to drive around and see them for yourself.
You will also need a good vacuum cleaner. Make sure it has smaller fittings. If your sunroof glass was shattered, you will need to remove all glass particles for sunroof to operate properly.
You will also need TORX bit screwdriver. You will not be able to do anything without the bit.
That's all you need.
Now, first thing you have to do is use vacuum cleaner to remove all glass particles. Use extensions if needed, but remove as much as you can. Make sure you DO NOT operate sunroof motor before removing glass particles. I made that mistake and whole procedure took me couple hours. If you operate the motor and there are glass particles inside, they will get on the rails and cause sunroof to malfunction.
Make sure you remove all glass particles you can. Next step is removing damaged glass lid. To remove the lid, you have to lift the sunroof up. Make sure you lift it up and not let it go under the hood. This is very important as it could safe you hours of labor.
Once the sunroof is up, remove side trims. They are secured by what appears to be a velcro, so you can easily remove them by hands.
Now each side has two TORX bolts. Take them off. It doesn't matter in what order you will remove them.
Once you removed 4 bolts, get outside of the vehicle and lift the damaged sunroof from inside. Take the sunroof out of the car carefully, making sure you don't damage the roof in the process.
Once that is done, use vacuum cleaner again and remove all glass particles. Look with a flashlight between roof and a headlining. If you see any glass particles there, be sure to remove them. Make sure you check sunroof rails. You definitely do not want to have any dirt or glass particles there as it will affect sunroof movement.
Remove that piece as well. It will help you with reaching further down the roof.
Once everything is clean, test your sunroof motor. Make sure it goes back and up with no issues. If there are issues, again make sure everything is clean and you don't see any dirt or glass particles in the whole sunroof assembly. If you still have issues, you may have a bad motor.
Once you checked that the motor moves sunroof brackets freely, it is time to install new glass lid. Gently put new glass lid on top of the bracket. Make sure it sits in correct position. Now, lightly secure all four bolts.
At this time, you could use a helper. While you are inside, get someone outside to help you with aligning the glass lid. It has to lay flat on the roof. Once you got it flat, secure all the screws.
Test the motor and make sure it opens up and closes properly. Now put back the side trims. Again, check sunroof functionality. If everything is working then you are all set.
