Why does the Baojun 730 one-touch window only go down but not up?

Because it lacks an anti-pinch function, the Baojun 730 one-touch window only goes down but not up. Here are some relevant details about the Baojun 730: 1. Powertrain: The Baojun 730-CVT version is equipped with a "1.5T turbocharged engine + simulated 8-speed CVT continuously variable transmission" powertrain combination. The engine has a rated power of 111kW and a maximum net torque of 250N/m. The turbo engages at around 1000 RPM, and by 1600 RPM, it can achieve the maximum torque comparable to mainstream 2.4L naturally aspirated engines on the market. 2. Fuel Consumption: Since its launch, the Baojun 730 has been renowned for its cost-effectiveness, especially the entry-level manual version, which has a fuel consumption of 8L per 100 kilometers.

I've been driving the Baojun 730 for a while now and have also encountered the issue where the one-touch window only rolls down but not up, which is quite a headache. It might be due to the window button sticking or wearing out from prolonged use—constantly pressing the 'down only' button can deform the contacts or allow dust buildup. Another possibility is the loss of initialization in the control module, such as when the system reset fails after the battery is disconnected. This poses significant safety risks; for example, during rain or cold weather, if the window can't close, rainwater may enter the cabin, damaging the interior or causing electrical shorts. It's advisable to promptly check the plugs and wiring connections, and if necessary, visit a professional repair shop to reset the ECU or replace the button assembly. Don't ignore this issue to prevent more serious circuit failures. For DIY cleaning, try using alcohol swabs on the buttons, but avoid forcing them open to prevent damage.

As an experienced driver, I believe that the one-touch window function of the Baojun 730 only lowering but not raising is mostly due to mechanical switch failure or motor position signal loss. Contact oxidation or internal spring failure prevents the rising signal from reaching the control box, especially after prolonged use or in humid conditions. The initialization steps are simple yet effective: first turn the ignition to the ON position, press and hold the window-up button for about ten seconds until the window fully closes, then release. If this doesn't work, it might be a blown fuse or a broken circuit requiring professional inspection—don't rush to replace the motor as it's costly and time-consuming. Remember to protect against dust during maintenance to extend its lifespan.

I use my Baojun 730 to pick up and drop off my kids. Lowering the windows is easy with just one press, but raising them requires holding the button manually, which is quite inconvenient. The mechanic said it's a common design issue, such as minor defects in the button's internal circuit board or burnt relay contacts, which are more likely to be triggered on rainy days with high humidity. Checking the fuse is the easiest solution—just see if there's any blown fuse in the box and replace it with a new one. It's a big safety hazard driving on the highway with windows open—kids might move around or bugs could get in, which is very annoying. Go to the shop for a thorough check-up as soon as possible to avoid motor damage and unnecessary expenses. Develop good habits like avoiding prolonged sun exposure on the buttons.
