Why is there water leakage at the sunroof switch of the Baojun 730?
2 Answers
Sunroof leakage is mostly caused by clogged drainage pipes. Simply clearing the drainage pipes to ensure smooth flow can resolve the issue. Below is relevant information about the Baojun 730: 1. Powertrain: Equipped with a "1.5T turbocharged engine + simulated 8-speed CVT continuously variable transmission" combination. The engine has a rated power of 111kW and a maximum net torque of 250N·m. The turbocharger engages at around 1000 rpm, and at 1600 rpm, it can achieve the maximum torque comparable to mainstream 2.4L naturally aspirated engines in the market. 2. Features: Standard 8-inch floating central multimedia screen, with higher trim models offering a 7-inch full LCD instrument panel. The vehicle comes with Car-play, SSP-LINK in-car connectivity platform, and other functions, supporting both Android and Apple systems simultaneously. 3. Interior: The new Baojun 730 automatic transmission features a fresh black-gray interior color scheme, complemented by dark wood-grain imitation panels on the dashboard, ice-blue ambient night lighting, and new dual-tone luxury seats, creating a layered, high-quality, and visually spacious interior feel.
My 730 also experienced water leakage around the sunroof switch. The main cause is likely an issue with the sunroof drainage system. The guide rail grooves around the sunroof usually have four drainage holes, which can easily get clogged with leaves and dust. During heavy rain or car washes, if the water can't drain quickly enough, it overflows into the headliner and drips down from the switch area. Additionally, aging and hardening of the rubber seals can lead to poor sealing. For DIY fixes, you can use a thin wire or compressed air to clean the drainage tubes—don't forget to clear the drainage outlets at the bottom of the car too. If the seals have hardened or deformed, it's best to visit a shop for replacements, otherwise, the constant dripping can be quite annoying.
