Where are the sunroof drainage holes located on the JAC Refine S3?
2 Answers
The sunroof drainage holes on the JAC Refine S3 are positioned at the four corners of the sunroof. Specifically, there is one each at the front left and right corners of the sunroof, and one each at the rear left and right corners of the sunroof. How the sunroof drainage holes work: Different types of sunroofs have varying designs, but the drainage holes are generally located at the four corners and feature a concealed design. Most vehicles are equipped with water retention channels, allowing rainwater to flow along the drainage channels through the A-pillar or C-pillar and eventually exit from the underside of the vehicle. If the drainage holes on both sides become completely blocked, water will be unable to drain properly and may flow along the roof toward the sunroof motor inside the vehicle. The importance of sunroof drainage holes: If the sunroof drainage system malfunctions, it can cause a short circuit or burnout of the sunroof motor, which is a common cause of electric sunroof failure. Additionally, detachment or damage to the drainage hose can lead to water leakage inside the vehicle.
I've driven a JAC Refine S3 for several years and once discovered water dripping from the roof during rain. It turned out to be clogged drainage holes. The holes are located at the four corners of the sunroof tracks. When you open the sunroof and look carefully at the ends of the tracks, you'll find a small hole in each corner. The front holes are positioned slightly forward for the front sunroof, while the rear ones are further back, connected to hoses that drain water underneath the car. If these holes get blocked by leaves or dust, water accumulates in the tracks and slowly seeps into the cabin, soaking the headliner or carpets, which can be costly and time-consuming to repair. I recommend cleaning them quarterly, parking away from trees when possible, and using a thin wire or compressed air to clear the passages. It's also good practice to check them quickly before driving, especially before the rainy season - simple maintenance can prevent major headaches. This is a common issue, and timely attention helps protect your interior and electronics.
