Why Do Windshield Wipers Always Leave Streaks?

Windshield wipers may leave streaks because the middle or tip of the wiper has lifted and cannot make full contact with the glass. First, wet the glass with water and run your hand back and forth across it. If there is dust on the glass surface, try wiping it several times with warm water, then gently rub it with your hand. Alternatively, you can use newspaper, rinse with water, and then feel the glass with your hand. Another option is to lightly sand the wiper blade or purchase a glass rain repellent. After prolonged exposure to wind and sun, windshield wipers will eventually wear out and cannot be repaired. At this point, the only way to achieve a clean wipe is to replace them with new ones. The position and angle of the wipers are crucial; any misalignment can cause shaking issues, naturally preventing a clean wipe. If this is the case, simply adjusting the wiper's position will solve the problem.

What is a Car Lightning Protector?

Car lightning protector is a transmitter and receiver used for GPS positioning and tracking. Here are the relevant introductions: Principle: Locally, by applying the communication principle of the CAN (Controller Area Network) bus, using an OBD-II connector, OLED display, and GPRS communication in diagnostic communication sessions, remote real-time tracking and monitoring can be achieved on the website. This system is designed based on chipKITMX7: (1) GSM module, which is based on the SIM900 modem and made using external charging technology for mobile phone batteries; (2) By using diagnostic sessions and PmodGPS positioning (GPS receiver), the GPRS connector sends data to a specific website; (3) At this time (relevant parameters about the car's status), the data is displayed on the PmodOLED2-4bit OLED display, achieving the effect of real-time tracking and monitoring.

How long after passing the subject two test can I schedule the subject three test?

Generally, you can schedule the subject three test 10 to 20 days after passing the subject two test. However, the specific scheduling time also depends on the number of test takers in your local area and the regulations of the vehicle management office. It is recommended that students clarify the local scheduling rules with their coaches to avoid missing the optimal time for scheduling the test. The rules for driving test scheduling rankings are as follows: First-time scheduling: The sorting time is based on the date when the user initially applied for a motor vehicle driver's license or other related services. Non-first-time scheduling: The sorting time is based on the date of the last test taken. Cancellation due to personal reasons: If a user who successfully scheduled a test cancels the appointment due to personal reasons, the sorting time is based on the cancellation date. If both the second and third scenarios apply: The most recent time is used as the sorting time.

What is the exam time for the first session of Subject 2?

Subject 2 is divided into two exam sessions: morning and afternoon. The first session (morning session) is scheduled from 8:00 AM to 12:00 PM. The second session of Subject 2 is from 1:00 PM to 6:00 PM (exam schedules may vary by region, so this is for reference only. Please confirm the actual schedule with your local testing center or consult with your instructor). Here are some related details: Meaning of Subject 2: Subject 2, also known as the Field Driving Skills Test, requires candidates to master basic methods of driving in designated areas and on-site roads. It evaluates the ability to properly use vehicle controls, accurately manage the spatial position of the vehicle, and precisely control the vehicle's position, speed, and route. Time limits for Subject 2: There is no overall time limit for Subject 2, but certain tasks have specific time constraints. For example, the reverse parking (parallel parking) must be completed within 210 seconds (starting from engaging reverse gear), or it will be considered a failure. The side parking task must be completed within 90 seconds, or it will be deemed a failure. For the hill start and stop, the vehicle must start moving uphill within 30 seconds after stopping.

What is the purpose of the barcode sticker on a new car's windshield?

The barcode sticker on a new car's windshield is used by the production plant for scanning purposes. Once scanned, the information is recorded in the computer system and becomes unnecessary after the vehicle leaves the factory. Here are some maintenance tips for car glass: Proper use of windshield washer fluid: There are various types of windshield washer fluids available on the market, mainly categorized into three types: summer-use windshield fluid, winter antifreeze windshield fluid, and special antifreeze windshield fluid. Summer-use windshield fluid is primarily used to remove insect residues from the glass surface, while winter antifreeze windshield fluid ensures that car components are not damaged when temperatures drop below -20°C. Applying window film: A thin layer of heat-insulating film can make a significant difference, not only blocking the intense sunlight but also providing heat insulation and UV protection. Car heat-insulating films are divided into front and rear windshield films and side window films. It is particularly important to avoid dark-tinted heat-insulating films on the front windshield. When selecting a heat-insulating film, the higher the UV protection index, the better, as it helps protect dashboard components from premature aging due to prolonged sun exposure. Purchasing glass insurance: This is a type of commercial insurance where the insurance company is responsible for compensating the insured vehicle for losses incurred due to the breakage of its glass during use. Glass breakage refers specifically to situations where only the windshield or window glass of the insured vehicle is damaged.

How to accurately check the car's engine oil?

Keep the car stationary for about 5 minutes; otherwise, the oil may not have fully flowed back to the oil pan, leading to an inaccurate check. Pull out the yellow oil dipstick, wipe it clean with a tissue, reinsert it, and then pull it out again to check. Typically, the dipstick has markings or scales divided into three sections, with the ideal oil level being between the upper and lower limits. Some cars are equipped with an electronic oil dipstick, making it easier to check. Checking the oil dipstick is simple: park the car on level ground, turn off the engine, wait for at least an hour, then pull out the dipstick to check the oil level. Generally, when the engine is cold, the oil level should be above 3/4 of the range between the upper and lower marks; when the engine is warm, the oil level should be above 1/2 of this range, indicating sufficient oil. Typically, checking once a week is sufficient. After the engine is turned off, the oil flows back into the oil reservoir from various parts, and the dipstick reading at this time is the normal value. After an oil change during maintenance, the oil filter is usually replaced as well. In this case, start the engine and let it idle for a few minutes before turning it off and checking the oil level when the engine is cold. This is because the new oil filter will fill with oil after the engine is started, causing a slight drop in the oil reservoir level. The dipstick reading may differ by about 2-3 mm from before the oil was filled.
