Sunroof electrical problems

The “sunroof electrical problems” that arise in a vehicle can cost a person heavily because the sunroof motor repair charges a person highly. Besides the electrical problem, other problems can prove to be very expensive. In this article, we will explain all the problems associated with the sunroof of a vehicle.

The sunroof is a feature on the car which makes the drive refreshing. But if the sunroof is not working properly, you can easily miss the enjoyment of inhaling the fresh air while the car drives at a cruising speed. 

The sunroofs are divided into two groups based on the way of installation. The two types are internal and external fitting. The internal sunroof is placed between the headliner and the roof’s skin. When the person opens the roof, it slides back into a hidden pocket. External sunroof sits on the top of the car’s roof, and it retracts back on the tracks built on the roof of the car. Some car sunroofs come with a spoiler sunroof feature that combines the sliding and pop-up action. 

Irrespective of the type of sunroof on your vehicle, the problems that the sunroof faces are common for both types of fittings. Mainly, the electrical problems face by a sunroof on a vehicle are the faulty sunroof switches, fault in the sunroof motor, blowing away of the sunroof fuse and faulty sunroof wiring. However, other problems can lead to a faulty sunroof on a vehicle. All the problems associated with the sunroof are mentioned below.

Sunroof electrical problems 

  • Fault in the sunroof motor.
  • Blown sunroof fuse.
  • Failure in the sunroof wiring.
  • Faulty sunroof switches.
  • Clogging of sunroof tracks
  • Leaking from the sunroof 

These are some of the common problems faced by the vehicle’s sunroof. These problems are explained in detail below.

Fault in the sunroof motor

Some sunroof stops working due to a mechanical fault or blown fuse. Others can stop working due to a faulty sunroof motor. One of the common symptoms of a sunroof with a faulty motor is that the sunroof stops opening and closing when the sunroof actuation button is pressed. Moreover, when you open the sunroof of a vehicle, a whining sound is produced by the motor. The sunroof motor has probably stopped working if you cannot hear that sound.

Blown sunroof fuse

Since the sunroof in most vehicles today is operated using electrical power, there are chances that excess voltage is supplied to the sunroof electrical motor due to some fault in the electrical circuit. Therefore, there are chances of the sunroof circuit catching fire in such a case. Hence to avoid accidental fire, a sunroof circuit is fitted with a fuse that blows away if there are chances of excess voltage supply to the sunroof motor. 

Failure in the sunroof wiring

The sunroof of a vehicle is operated with the help of electricity. Hence there are chances that the sunroof wiring might get damaged due to frequent use. Also, the sunroof is exposed to rain. Thus the entrance of the slightest of water in the electrical wiring can cause the wiring to malfunction. 

Faulty sunroof switches

The sunroof switch is present next to the interior cabin light. The switch consists of metal contacts that might get worn out easily. Warning out of the sunroof switches can be due to rusting of metal contacts. Rusting of the metal contacts leads to improper working of the switch. Therefore in such a case, you need to open the switch of the sunroof and then clean it. If the rusting is more, you need to replace the complete sunroof switch.

Clogging of sunroof tracks.

Sometimes, the sunroof guide tracks on which the roof retracts are blocked. This fault can arise due to chipping away of some sunroof mechanism components or sticking some external debris on the sunroof track. Thus it becomes essential to clean the sunroof track frequently, especially on a car having a panoramic sunroof because the tracks of a panoramic sunroof are present on the top of the car roof.

Water leaking from the sunroof

The sunroof has rubber seals present around it. These seals are responsible for restricting water from entering the car’s cabin. However, these rubber seals can get damaged due to continuous exposure to heat generated by the sunlight. Moreover, if there are cracks on the sunroof glass, water can seep through these cracks. Hence, you need to replace the rubber seals or fix the glass cracks to prevent the water from entering the car’s cabin.


In this article, we have successfully addressed “Sunroof electrical problems”.
