Many people complain that the windows and sunroof of their car automatically open without pressing any activation button. Windows are controlled by the buttons present on the side of the door.
Car windows and sunroof open by themselves because of the activated convenient feature, pressing the key fob button, moisture in the position switch, weak key fob batteries, faulty electrical systems, and software issues.
The situation worsens during rainy or snowy seasons because water can enter the interior cabin and damage the different components of the vehicles.

Activated convenient feature
Most cars have convenient features for the ease and comfort of people. However, the vehicles usually get hot in the summer when you park them in uncovered parking areas.
The heat from the outside and the sun can cause an accumulation of heat inside, and you can also feel a hot environment and suffocation when you open the driver’s side doors.
The vehicles contain a convenient mode to resolve the problems of summer. The convenient feature is connected to the sunroofs and windows of your vehicles.
It can open and close them according to the temperature. It can open the sunroofs and windows after detecting the heat in the inner cabin and making the conditions favorable for people.
The opening of these components makes the interior less hot, and you can sit in them comfortably. Many people activate the convenient feature and then forget to deactivate them.
It is challenging for you to cope with the situation in rainy weather. You can deactivate this feature and pressing and pressing the lock on its key fob.
Pressing of key fob button
You can control the convenient features in cars that are helpful to open and close the sunroof and windows using the key fob.
The key fob contains the lock and unlocks buttons to engage and disengage this mode. People often complain that they do not press the unlock button, but they can see their cars’ open windows and sunroofs.
The issue comes when you unintentionally press their unlock button. People put the key fobs in the pocket of their pants to keep them safe.
You can unknowingly press the unlock buttons when you sit on chairs with key fobs in your pockets. The slight pressure on buttons activates this feature, and you do not have information about it.
In addition, the issue also comes when you wear skinny or tight jeans pants. However, the ladies can also put the remote controls in their handbags.
These key fobs are highly functional and can interact with your cars easily when they are present at a far distance. Keep the remotes in your hands when sitting or in your wallets.
It is better to check the activation of unlock button frequently so you cannot see snow on the car seats when you wake up.
Moisture in position switch
The position switch is present on the driver’s side in some cars that perform the same function and help lock and unlock the sunroof and windows.
It is located on the right armrest side of driver seats in some models of cars. The presence of a position switch button depends on the model, brand, and type of vehicle.
Sometimes these buttons become faulty and function abruptly. These can open both of these components by themselves without pressing any button.
The issue comes when moisture enters these switches. Moisture enters them when you keep the doors open during rainy seasons.
The poor sealing of doors also allows moisture to enter this door module. The issue also comes when water or other liquid accidentally spills on them.
Remove the moisture from these areas. Use the hairdryer at normal heat to dry the moisture from the switches.
You have to call the mechanic when you cannot resolve the issue after drying of moisture.
Weak batteries of key fob
Many people face the frequent opening and closing of sunroofs and windows. They complain they locked both of these components, but they open when they return.
The water can enter the carpets during rain, and you can feel the smell from the interior cabin. Moreover, the entrapped moisture in floor carpets allows the molds to grow.
The issue comes from the weak batteries of the cars and key fobs. The uneven functioning occurs when their batteries are weak and cannot transmit signals properly.
People deactivate or lock the system, but these remain unlocked due to weak batteries. Replace the car and key fob batteries if these are weak and dead.
Faulty electric system
The electric system is necessary to drive the sunroof and power windows in cars. These open themselves, and you cannot close them because of an interruption in the electricity supply.
The driven cable can also get damaged and has insufficient supply to close the sunroof. In addition, the issue also comes from their faulty motors.
The motor is connected to a sliding system for its proper functioning. The motor is an electric component and can malfunction at any time.
The dead motors cannot operate, and you cannot close them after activating convenient mode in cars.
Moreover, these can function unevenly because of faulty switches and broken fuses. The water can enter the inner side when these remain open.
Water can damage the leather upholstery of the seats and decrease their durability. Furthermore, the low temperature outside can disturb people during winter.
You should inspect the sunroofs’ dead motors, fuses, and switches.
Software problem
The key fobs are programmed into the cars through specialized software. These take the signal and, in return, activate or deactivate the various features of your vehicle.
The software becomes faulty, and you can see a glitch in its functioning. The software glitch leads to programming issues and uneven functioning of various components.
Many people complain that they park their vehicles in the parking lot with closed windows and sunroofs, but they are open when they return.
The issue comes from poorly programmed software. These cannot detect the proper and correct signals from the key fob and perform function unevenly.
The uneven functions also come when there is a bug in the software. You should restart the software and call the mechanic for this procedure.
Sometimes you do not know about the restarting procedure, so it is better to call the expert.
