The reasons for the wiper not returning to its original position are: 1. Aging of the wiper rubber; 2. Presence of dust or other foreign objects between the rubber and the windshield; 3. Wiring fault; 4. Motor fault; 5. Wiper switch fault. The function of the wiper is to remove raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety. The method for removing the wiper is: 1. Fully lift the wiper and adjust the angle of the blade; 2. Change the angle of the wiper blade so that it forms a 90-degree angle with the wiper arm; 3. Once positioned at the angle, you can start the removal process. Lift the rubber blade, remove the entire wiper blade, separate the rubber blade horizontally, press down on the main bracket, and the entire wiper blade can be removed.

I think the wipers not returning to their original position might be due to the wiper linkage being stuck or a problem with the motor. I've driven quite a few cars and encountered this issue several times, especially during heavy rain when the wipers not working can be very dangerous. The linkage is that metal rod connecting the motor to the wiper arms; over time, corrosion or rust from rainwater can cause it to bend and get stuck, preventing the wipers from moving and leaving them halfway. As for the motor, if the internal gears are worn or there's an electrical fault, the wipers may move sluggishly and stop midway. Additionally, if the wiper arms are installed too tightly or have become loose, it can affect their positioning, causing them not to return accurately. I recommend checking the wipers' movement regularly before driving to ensure they operate smoothly and aren't clogged with debris. If you notice any issues, get them fixed immediately—don't delay, because safety comes first, especially when driving at night. Also, different car models have varying designs, and older cars are more prone to such failures. Regular maintenance can prevent most problems, including clearing debris under the windshield to protect the linkage—something I've learned from experience. Addressing small issues early can save you from bigger troubles later.

What is the vehicle pickup sequence when a 4S dealership handles license plate registration?

Below is the vehicle pickup sequence when a 4S dealership handles license plate registration: 1. Vehicle Certificate of Conformity: Confirm whether the vehicle certificate of conformity is delivered with the vehicle or determine the delivery time to avoid delays in vehicle registration caused by the 4S store's late delivery of the certificate. 2. Keep the triplicate car purchase invoice: After purchasing the car, the 4S store will issue a triplicate car purchase invoice, which must be kept properly. The invoice usually has red, yellow, and blue copies, with the red and yellow copies to be submitted and the yellow copy to be kept by the buyer. 3. Pay the vehicle purchase tax and obtain the original and duplicate tax certificates: After purchasing the vehicle, the vehicle purchase tax should be paid as soon as possible. 4. Prepare license plate registration documents: Prepare the original and photocopy of your ID card in advance. 5. Vehicle registration and inspection at the DMV: With all the necessary documents, you can go to the DMV to register and apply for a license plate. First, the vehicle will be inspected by a designated traffic police officer. 6. Select a license plate number: After the vehicle inspection, you can go to the DMV hall to choose a license plate number. Generally, there are two options: self-selection or random selection. 7. Pay the fee and wait for the license plate: After selecting the number, pay the fee and wait for the license plate, which usually takes three to five working days to receive.

Are there any issues with the discounted cars at 4S stores?

Discounted cars at 4S stores are generally inventory cars, test drive vehicles, or display cars, which typically don't have major issues. When purchasing discounted inventory cars at a 4S store, it's essential to thoroughly understand the vehicle's specific condition before making a decision. Don't let promotional activities cloud your judgment. Identifying whether a car is an inventory vehicle is straightforward—just check the manufacturing date on the vehicle's nameplate. Below are the types of discounted cars available at 4S stores: 1. Inventory Cars: These are vehicles that have spent their inventory period at the manufacturer's warehouse. The condition of these cars can be trusted because manufacturers have strict regulations for managing inventory cars, often prohibiting outdoor storage. Additionally, the Pre-Delivery Inspection (PDI) ensures the vehicle meets standards before leaving the factory, and the manufacturing date can be verified through the documents. 2. Test Drive Vehicles: Test drive vehicles usually offer the most significant discounts. However, their odometers will show some mileage due to numerous customer test drives and even frequent use by 4S store staff for errands. If the vehicle has exceeded its break-in period, it's best to avoid purchasing it. 3. Display Cars: A useful tip when buying a car is to consider purchasing a dealer's display car. Display cars are carefully selected by the dealer before being placed in the showroom, rarely moved, and maintained daily by dedicated staff. They are also relatively cheaper, so their condition can be trusted.

What are the dimensions of the 2022 Mitsubishi Outlander?

2022 Mitsubishi Outlander has a body size of 4680mm in length, 1860mm in width, and 1747mm in height, according to official data. The length of the 2022 Mitsubishi Outlander refers to the distance between two vertical planes perpendicular to the vehicle's longitudinal symmetry plane and touching the outermost protruding parts at the front and rear of the vehicle. The width refers to the distance between two planes parallel to the vehicle's longitudinal symmetry plane and touching the outermost rigid fixed protruding parts on both sides of the vehicle. The height refers to the distance between the highest point of the vehicle and the supporting plane of the vehicle. The 2022 Mitsubishi Outlander is equipped with a 2.5-liter naturally aspirated four-cylinder engine, delivering a maximum power of 184 horsepower and a peak torque of 245 Nm, with a 0-100 km/h acceleration time of 8.6 seconds. There are national regulations regarding vehicle dimensions. According to the national standard "GB1589-89," the total width of a vehicle does not include side mirrors. The limitation on vehicle width is to provide sufficient lateral clearance for overtaking between adjacent lanes. This means that, according to national standards, the significance of vehicle width data lies in ensuring enough space during overtaking to prevent accidents due to excessive width or situations where road markings are narrower than the vehicle's width. Additionally, the national regulation stipulates that the total width of a vehicle must not exceed 2.5m to meet the usage requirements of public roads.

Does the Emgrand require a decoder when retrofitting xenon lights?

The Emgrand does not require a decoder when retrofitting xenon lights; only an HID ballast needs to be added. Xenon Light Decoder: A decoder is essentially a resistor or capacitor component on the power supply side. It is connected in series in the 12V circuit of the ballast to prevent the vehicle's computer from triggering an alarm. Different vehicles require different decoders, mainly to address issues like insufficient xenon light power or interference with the vehicle's computer. The decoder is typically a small plastic box. Components of Xenon Lights: HID xenon lights generally consist of a bulb (xenon lamp), an electronic ballast (also known as a stabilizer, voltage regulator, or transformer), and a wiring control box.
