What Causes Severe Vibration When the Air Conditioning is Turned On in a Buick Excelle?

Buick Excelle experiences severe vibration when the air conditioning is turned on due to a dirty throttle body and insufficient engine power. Insufficient engine power: When the engine power is low, high idle speed indicates that the compressor is working. When the compressor is not operating, the idle speed drops, and the steering wheel does not vibrate. When the air conditioning is turned on during normal driving, the increased load from the compressor causes the engine speed to decrease, resulting in noticeable vehicle vibration. To address this issue, manufacturers typically install an engine idle speed boost system for air conditioning. This system increases the engine speed to the required range when the air conditioning compressor is active. Dirty throttle body: A dirty throttle body affects engine performance. Turning on the air conditioning under these conditions further increases the engine idle load, leading to steering wheel vibration. Cleaning the throttle body can prevent this issue. The vibration caused by air conditioning use, based on current vehicle conditions, is likely due to a dirty throttle body. It is recommended to have it cleaned at a repair shop. According to current vehicle control technology and maintenance cases, this is a common issue. Throttle carbon buildup is primarily caused by the engine control unit's characteristics, as well as factors such as low temperatures, low-speed driving, short-distance trips, and frequent starts. The noise from the air conditioning system is normal compressor operation, and no other issues are likely present. The engine drives the air conditioning compressor to provide cooling, which is a heavy load for the engine. When the air conditioning is turned on, the engine must also power the compressor, leading to noticeable power loss and increased vibration. This effect is more pronounced at idle speed. Increasing the idle speed slightly may improve the situation, though it will result in higher fuel consumption.

Where is the Body Control Module Located in the Magotan?

The body control module of the Magotan is located under the hood, inside the engine compartment, at the upper left corner of the engine, next to the battery. The specific functions of the body control module are as follows: 1. Power Management: The BCM has power management capabilities, integrating the power supply of electrical equipment in the vehicle into the BCM, which saves wiring harnesses and facilitates later maintenance. 2. Light Control: When the BCM detects a short circuit to ground or excessive current in the small light circuit, it activates a protection function to prevent the vehicle's wiring harness from burning due to excessive current. 3. Wiper Control: The wiper circuit in a car is relatively complex. Using conventional control would require a large number of wiring harnesses, but with the BCM, wiring harnesses can be significantly saved, and additional wiper functions are added, such as manually adjusting the speed of the intermittent wiper setting. 4. Central Locking and Remote Control Reception: When the BCM detects that the vehicle speed increases from less than 10 KM/H to 10 KM/H and the door lock is in the unlocked state, it performs a locking operation. If the door lock is already locked, no action is taken. Additionally, after the remote sends a wireless signal to the BCM, it can control the door locks, such as locking, unlocking, opening the trunk, and locating the vehicle. 5. Vehicle Anti-Theft and Engine Immobilizer Control: When the vehicle's anti-theft system is successfully activated and the vehicle is illegally accessed, the horn will sound and the alarm lights will flash to alert the owner. With the engine immobilizer activated, even if someone duplicates the car key, they cannot drive the vehicle away. 6. Fault Mode Self-Diagnosis Control: When the BCM detects an internal fault, it activates its self-diagnosis function, displaying a fault indicator on the dashboard to remind the owner to perform maintenance. Additionally, specialized equipment can be used to read data from the BCM to assist in repairs.

What Causes the Hissing Sound When a Car Goes Over a Speed Bump?

Car makes a hissing sound when going over a speed bump due to the working principle of the shock absorber itself. When the vehicle passes over a bumpy road, the entire shock absorber is compressed, thereby compressing the external spring. However, after the vehicle passes the bumpy section, the spring's elasticity will reset the shock absorber. During this compression and resetting process of the shock absorber, a hissing sound is produced. Introduction to the Shock Absorber's Functioning Process When Going Over a Speed Bump: The most common type of shock absorber in household cars is the twin-tube shock absorber. What is visible externally is the outer tube of the shock absorber, inside which there is a set of piston and piston tube structure. The piston has valves, and the space between the piston, piston tube, and outer tube is filled with shock absorber oil. When the shock absorber is compressed, the piston squeezes the shock absorber oil, with some of the oil flowing through the valves into the upper part of the piston, and another part flowing into the outer tube of the shock absorber. When the shock absorber resets, the piston moves upward, and the shock absorber oil in the outer tube replenishes the piston tube. Simultaneously, the shock absorber oil in the upper part of the piston moves downward. The damping force is generated through the obstruction effect of the shock absorber oil, dissipating the impact force. Therefore, when the shock absorber is compressed or reset, the internal shock absorber oil flows rapidly, producing a hissing sound. Precautions When Going Over a Speed Bump: When encountering a speed bump while driving, reduce the speed early and then pass over the speed bump straight, balancing the impact force on both tires to ensure the suspension system on both sides bears the force evenly. Do not slam on the brakes or press the accelerator, allowing the vehicle to pass over the speed bump purely by inertia. This approach is both safe and protective of the vehicle's suspension and steering systems, causing minimal damage to the car.

Is It a Violation to Stop Halfway After Running a Red Light?

Stopping immediately after running a red light still counts as running a red light. Article 10 of the "Measures for the Scoring of Road Traffic Safety Violations" stipulates that running a red light results in 6 penalty points and a fine of 200 yuan. The "Measures for the Scoring of Road Traffic Safety Violations" has increased the penalties for running a red light. To determine whether a vehicle has run a red light, three photos are used as evidence: one before the vehicle crosses the line, one after it crosses the line, and one when it enters the intersection. The photo of the vehicle entering the intersection can clearly show whether the vehicle forcibly passed through during a red light. Running a red light refers to the behavior where the vehicle, while still within the stop line, continues to move forward despite the traffic light being red, and both the front and rear wheels of the vehicle completely cross the stop line. This is determined by capturing three photos via electronic cameras: A photo of the vehicle crossing the stop line at the intersection, showing the red light and the license plate number. A photo of the vehicle completely crossing the stop line, showing the red light and the license plate number. A photo of the vehicle continuing to move, comparing changes in the vehicle's position, showing the red light and the license plate number. If these three photos are captured, the vehicle is determined to have run a red light. Running a red light is not considered a violation under the following circumstances: Yielding to emergency vehicles: Yielding to ambulances, fire trucks, or other emergency vehicles. If a violation is captured by surveillance cameras due to yielding to such vehicles, manual review will not record the act of running a red light. Even if recorded, you can apply for reconsideration at the traffic police department. Extreme weather: When visibility is so low that even electronic police cannot clearly see the traffic lights. Photos of the violation may be blurry, and if you accidentally run a red light, the traffic police will not impose penalties. Emergency situations: If a citizen transports a patient with acute symptoms, they can provide proof from the hospital or the person being assisted to the traffic police for verification. If confirmed, the violation record can be expunged. If possible, it is best to call an ambulance to avoid traffic accidents caused by running a red light. Traffic police directing:
