Common reasons for uneven cooling in car air conditioners include: air vent issues, where one of the air vent servo motors is faulty, causing one side to not cool; the air valve plate being stuck, obstructing its rotation and affecting airflow on one side; blockage in one side of the air duct; or, if it's an automatic air conditioner, the dual-zone control function might be activated. Types of car air conditioners: 1. Independent type: Uses a dedicated engine to drive the compressor, offering high cooling capacity and stable operation, but with higher costs, larger size, and weight, commonly used in large and medium-sized buses. 2. Non-independent type: The compressor is driven by the car engine, with cooling performance significantly affected by engine operation, resulting in less stability, mostly used in small buses and sedans.

What Are the Reasons Why a Car Sunroof Won't Open?

Regarding the reasons why a car sunroof won't open and the solutions, the following are provided: 1. The drive motor of the car sunroof is damaged. Check the sunroof wiring and ensure the wiring is normal, then replace the damaged sunroof motor. 2. The sunroof track is severely lacking lubrication, causing the sunroof seal to stick to the car body. Replace the sunroof seal. 3. There are foreign objects stuck in the sunroof slot. Simply remove the foreign objects. Additional information: 1. Opening the sunroof in the morning: Releases harmful gases. After a period of being sealed, the air inside the car cabin contains more harmful chemicals such as benzene and formaldehyde. The first thing to do after getting in the car in the morning is to open the sunroof, utilizing its superior negative pressure ventilation principle to quickly expel harmful gases from the car. 2. Opening the sunroof during traffic jams: Prevents exhaust fumes from entering the car. During traffic jams, all vehicles are stationary, and car exhaust will inevitably spread in the surrounding air. At this time, open the sunroof and close the side windows, and the exhaust fumes inside the car will be quickly expelled.

How to Improve the Sound of Car Door Closing?

The rattling sound of metal sheets can severely disrupt the desired dull thud of a car door closing, thus necessitating the use of damping materials to improve the sound. Methods to enhance the door closing sound are as follows: 1. High-quality doors equipped with dual sealing strips will exhibit improved closing sounds. 2. Soundproofing all four doors by applying vibration damping sheets and sound insulation cotton to the door panels can enhance the closing sound. 3. Loose wiper strips along the lower edge of some door windows can cause significant window shaking when the door is closed with the window halfway down, resulting in a loose sound. Inserting an appropriately sized O-ring into the wiper strip to tighten it against the window can reduce window shaking during door closure, effectively improving the sound.

What items are included in the driver's license physical examination?

The driver's license physical examination includes height, vision, color discrimination, hearing, and limb motor function. Below are the relevant details about the driver's license physical examination: Items included in the driver's license physical examination: Height: Applicants for large passenger vehicles, tractors, city buses, large trucks, and trolleybuses must be at least 155 cm tall. Applicants for medium-sized passenger vehicles must be at least 150 cm tall. Vision: Applicants for large passenger vehicles, tractors, city buses, medium-sized passenger vehicles, large trucks, trolleybuses, or trams must have uncorrected or corrected visual acuity of at least 5.0 on the logarithmic visual acuity chart. Drivers undergoing the physical examination must present their identification: driver's license (original and copy). They must fill out the driver's review and license renewal application form truthfully and attach a recent one-inch passport-sized photo. Regulations for the driver's license physical examination: The new regulations stipulate that individuals with hearing impairments who meet the required hearing standards with hearing aids can apply for a license to drive small cars and small automatic transmission cars. Individuals missing the right thumb or with incomplete finger joints can also apply for a license to drive small cars and small automatic transmission cars. "Allowing the absence of the right thumb is a new regulation," which takes into account that the right hand mainly assists in steering and gear shifting, with minimal reliance on the thumb. "However, individuals with disabilities in the right lower limb or both lower limbs, as well as finger disabilities, cannot apply for a driver's license." Disabled individuals applying for a special small automatic transmission passenger vehicle license must meet higher upper limb requirements. Therefore, the regulations specify that the upper limbs must comply with general standards: both thumbs must be intact, and each hand must have at least three other fingers intact, with normal limb and finger motor function.
