If your sunroof is stuck open, it can be a big problem, especially if you are expecting snow or rain. Let’s look at what you can do about it.
The sunroof is one of the best accessories in most car models. They are present on the car roof and allow extra light and air to enter the passenger cabin.
But if your sunroof is stuck open on a windy or rainy day, it will allow water, dust, and debris to enter the car cabin, which is quite annoying and frustrating.
There can be various reasons behind the problem. For instance, if there is an issue with the sunroof motor, you will face the problem. Additionally, if so much dust and dirt get collected on the track, then the sunroof will not close.
What Is A Sunroof?
The sunroof is located on the roof of the car. It features a transparent glass panel that opens and closes with a single button. It has mainly two purposes. The first is to allow fresh air into the car cabin, and the second is to enable the sunlight to get inside the car.
Versions Of Sunroof
#1. Pop Of Sunroof
Pop of sunroof is one of the easy options that the car manufacturer can add. It has no motor or any moving parts. There are simple locks that hold the sunroof glass panel in its position.
