Power moonroof is not opening Inspection Service

Whether you call it a moonroof or a sunroof, the fact remains that these automotive accessories offer enhanced enjoyment. They can let in fresh air and natural light, and they can also increase your vehicle’s value if you decide to sell it. However, there are potential problems here that might render your power moonroof inoperable.

How this system works:

A power moonroof should offer two forms of functionality. First, it should tilt up at the back. This allows it to be used as a vent while you’re driving, without having to open the entire window up. Second, it should retract almost all the way into the roof to allow in fresh air. When closed, it will let in light, but not air.

Your moonroof consists of several key components. There’s the window itself. There are also run channels on either side that allow it to slide back and forth during operation. Finally, there’s a motor that operates the entire thing, which is connected to a switch located somewhere in your cabin – it’s generally located on the ceiling, in front of the moonroof, but this varies depending on the make and model you’re driving.

When you press the “vent” button, the back of the moonroof tilts up, venting the cabin. When you open the moonroof fully, it slides in the run channels until it reaches the desired position. Pressing the close button makes the moonroof slide forward again, until it seals.

Common reasons for this to happen:

  • Debris in Run Channels: One of the most common problems with power moonroof systems is the potential for debris to accumulate in the run channels. This can include dust, dirt, pollen, and even leaves and small twigs. Eventually, the debris jams the run channels, and the moonroof won’t operate, either because the motor is overheated, or because the run channels are completely blocked.

  • Overheating Motor: As mentioned above, if debris blocks the run channels, it can cause the motor to overheat. Many have overheat protection built in, and will shut off if the motor’s temperature exceeds a safe rating. Overheating can also be caused by a lack of run channel lubrication (grease), which causes unnecessary friction and heat.

  • Blown Fuse: Like most electronic components on your car, your power moonroof has a fuse that protects the system from voltage spikes. If the fuse blows, the moonroof will not open or close (and may be stuck open if that was the moonroof’s position when the fuse blew).

  • Failed Switch: Your moonroof requires a switch to operate. If the contacts are worn in the switch, the moonroof will not work correctly. It might not operate at all, or it may move only in one direction.

What to expect:

A top-rated mobile mechanic will come to your home or office to inspect the moonroof, switch, run channels and motor. The mechanic will then provide a detailed inspection report that includes the scope and cost of the necessary repairs.

How it's done:

The mechanic will need to inspect the moonroof, beginning with the run channels and including the fuse, the motor, the switch and other components. The length of the inspection and diagnosis will depend on both the symptoms you’re experiencing, as well as the underlying problem and the difficultly involved with determining the cause.

How important is this service?

Having an operational moonroof is important for enjoyment and convenience. Not only that, but if your moonroof stops working while open or partially open, it can be very problematic. Rain and other precipitation can enter the vehicle, and it also compromises your ability to maintain a comfortable temperature inside.

The best defense against power moonroof problems is ongoing professional maintenance (run channel cleaning and lubrication on a regular basis). One of our professional mechanics can inspect your system and determine what’s gone wrong, as well as providing you with the needed repair.
