How to open the sunroof
The Jeep Grand Cherokee offers two types of sunroofs: the CommandView® Dual-Pane Panoramic Sunroof and the Power Sunroof with Express-Open/Close. The panoramic sunroof features a single sliding-glass panel in the front that can be opened rearward for additional fresh air.

To open the panoramic sunroof, locate the one-touch auto-open button. Press and hold the button until the sunroof reaches your desired level of openness. Depending on the outside temperature, you may need to press the button multiple times to fully open the sunroof.
It is important to regularly maintain your panoramic sunroof to ensure proper functioning and avoid common issues such as leakage, deformation, and odd noises. Remove leaves, pollen, water, and other debris from the sunroof every few days to prevent blockage and keep the drainage system clear.
To reset the sunroof, follow these steps:
- Close the sunroof fully.
- Move the sunroof switch to the Vent position after 10 seconds.
- Release the sunroof switch, then push and hold the switch forward again within 5 seconds to initiate the relearn process.
- Allow the sunroof to complete one full cycle and return to the Fully Closed position.
- Once the sunroof is closed, release the sunroof switch. The sunroof is now reset.

How to close the sunroof
The Jeep Grand Cherokee offers a panoramic sunroof with a power sunshade and power sunroof control buttons located between the sun visors. The sunshade control is on the right, and the sunroof control is on the left. To close the sunroof, simply push the control towards the front. You can also control the sunroof manually.
It is important to maintain your Jeep Grand Cherokee's panoramic sunroof to ensure it functions properly and to prevent issues. Regularly remove leaves, pollen, water, and other debris from the sunroof to avoid blockage and keep the drainage system clear. Over time, dirt and debris can cause corrosion and rust, leading to damage.
If you encounter problems with the sunroof opening and closing, it could be due to various issues. A broken latch, a bent rail, or a worn-out seal are common causes. A weak or dead battery may also be the culprit, in which case, you should try recharging the battery or replacing it if necessary. Ensure that the new battery is compatible with the electric components of the sunroof.
In some cases, the sunroof motor may be the issue. Before replacing it, verify that the problem is indeed with the motor and not due to overheating. Replacing the motor typically costs between $760 and $920, including labor. To access the sunroof motor, make sure the sunroof is closed, and the Jeep is parked on level ground. Then, carefully remove the vehicle's headliner.

Sunroof maintenance
The sunroof in your Jeep Grand Cherokee is a great feature, but it needs to be maintained properly to avoid common problems such as leakage, deformation, and odd noises. Here are some detailed instructions on how to maintain your sunroof to keep it in perfect working condition:
Cleaning and Maintenance
Firstly, it is important to keep the sunroof clean and clear of debris. Remove any leaves, pollen, water, or other substances that may block the sliding roof. This should be done regularly, at least once every few days, to prevent dirt and debris from accumulating in the drainage system and causing rust and damage.
Drain Tubes
It is crucial to regularly check and maintain the drain tubes of your sunroof. These tubes can be found in the back of most cars and are usually easily accessible. Remove one tube at a time and inspect for any clogs or damage. Clean the tubes with a toothbrush or rag if there is any debris present. Ensure that all tubes are clear of restrictions or blockages to prevent drainage issues.
Glass and Seals
Inspect the sunroof glass for any signs of UV exposure, chipping, cracking, or scratches. Ensure that there are no leaks around the seals and gaskets. Keep the seals lubricated to prevent them from sticking and causing further issues. You can use silicone spray on the rubber seals to keep them soft and lubricated.
Lubrication
Lubricate the sunroof mechanism every few months to ensure smooth operation. Apply grease evenly to all parts of the mechanism and spread it with your fingers until it is completely covered. This includes the hinges and guides of the sunroof wind net, as these are considered wear items.
Resetting
If you encounter issues with your sunroof, one of the best ways to solve them is to reset the sunroof. This can help fix problems with the wiring, motors, and other components, ensuring they work properly.
By following these maintenance steps, you can keep your Jeep Grand Cherokee's sunroof in good condition and enjoy the benefits of fresh air and scenic views without encountering common sunroof problems.

Common sunroof problems
Sunroofs are a great feature, but they can also be a source of frustration if you encounter common sunroof problems. Here are some issues that you may face and ways to address them:
Leaking:
A leaking sunroof can be a significant issue, as water seeping into the interior of your car can cause damage. Leaking is often due to a clog in the sunroof drain or worn-out rubber seals. To fix this, clear any clogs and replace the seals. It is important to address this issue promptly to prevent further complications.
Deformation:
Placing heavy objects on the roof of your vehicle can cause the sunroof glass to deform, affecting its positioning and shape permanently. Deformation prevents the sliding roof from operating correctly. To resolve this, inspect the glass for any bends or cracks, and if found, replace the glass with a new one.
Odd Noises:
Strange noises coming from the sunroof when sliding it open or closed can be irritating and indicate underlying problems. This issue is often related to wiring problems, which can also impact the sunroof's performance and movement. It is recommended to have a professional technician diagnose and address wiring issues.
Scratches and Cracks:
Sunroofs are susceptible to scratches and cracks, which can compromise the tint on the glass and increase the risk of shattering while driving. These scratches and cracks can be caused by small rocks, weather changes, or the use of harsh cleaning products. To fix small scratches, a glass scratch repair kit can be used, while noticeable cracks may require glass replacement.
Sunroof Maintenance:
Regular maintenance and cleaning of your sunroof are crucial to preventing problems. Remove leaves, pollen, water, and other debris from the sunroof to keep the drainage system clear. Built-up substances can cause corrosion and rust, impacting the proper functioning of the drainage system. Proper maintenance ensures that the sunroof's wires, motors, and other components remain in good working condition.
While sunroofs can present challenges, many issues have simple solutions, and with proper care, you can enjoy their benefits without frequent hassles.

Sunroof repairs
The Jeep Grand Cherokee offers two types of sunroofs: the CommandView® Dual-Pane Panoramic Sunroof and the Power Sunroof with Express-Open/Close. While the former comes standard on several 2019, 2020, and 2021 models, the latter is available on select models. The Power Sunroof with Express-Open/Close can be opened, closed, or vented with the simple push of a button.
Sunroofs are intricate systems with many components, and issues with them are not uncommon. Some of the common problems with the Jeep Grand Cherokee's panoramic sunroof include leakage, deformation, and odd noises. Here are some general guidelines for repairing sunroofs:
Leakage
Sunroof leaks can cause noticeable stains and discolourations on the interior of your car, including the headliner and pillars. To identify the source of the leak, flush the sunroof with water and observe how the water flows through the drains. Check the drain tubes for debris or clogging, and ensure there is no damage to the tubes. Use a shop vacuum or a wet/dry vacuum to remove any debris. If the clog is stubborn, use an air compressor, but do not exceed 30 psi of pressure to avoid damaging the tubes. Replace any faulty seals and ensure the weather stripping is aligned and in good condition.
Deformation
Deformation of the sunroof glass can occur when heavy objects are placed on the vehicle's roof, affecting the positioning and shape of the glass permanently. To fix this, inspect the condition of the glass, and if it is bent or cracked, replace it with a new one.
Odd Noises
Strange noises during the operation of the sunroof can indicate a problem with the wiring of the vehicle. This issue can also affect the performance or movement of the sunroof. Consult a technician to diagnose and repair any wiring problems.
Other Issues
Other common issues with sunroofs include failure to open or close, which can be caused by debris in the tracks or malfunctions in the electrical or mechanical systems. Regular cleaning of the sunroof tracks is important to prevent debris buildup. If the sunroof is stuck, a technician will inspect the fuses, motor, wiring, switches, regulator arms, brackets, and channel guides to determine the cause of the problem and make the necessary repairs.
In the case of a shattered sunroof, temporary solutions include using automotive tape, duct tape, or silicone to cover the broken area until you can get it repaired. Contact a reputable auto glass shop or a specialty shop to replace the sunroof glass, especially if the replacement parts are difficult to find for your specific model.
For more complex issues, it is recommended to consult a certified technician or a specialised repair centre, such as NAPA Auto Care, which has experience in handling sunroof repairs.
