The reasons for the Citroen C-Quatre's air conditioning not cooling are: 1. Damage to the piston inside the air conditioning system. 2. Damage to the clutch plate. 3. The engine ECU does not instruct the air conditioning to work. 4. The condenser fins in the air conditioning system are too dirty, causing the pressure and temperature in the system to rise too high. To protect the system, the air conditioning pump stops working, resulting in no cooling. Additional information: The cooling principle of car air conditioning is the same as that of household air conditioning. Both use the principle that R12 or R134a expands rapidly when compressed and released, absorbing a large amount of heat. In the cooling system, the low-pressure vapor of the refrigerant is sucked in by the compressor, compressed into high-pressure vapor, and then discharged to the condenser. The indoor air continuously circulates to achieve the purpose of lowering the temperature.

When reversing into a parking spot, should you look at the front or rear door handle?

When reversing into a parking spot, observe the rear door handle. Below is an introduction to reverse parking: 1. Introduction: Reverse parking has been a mandatory test item for obtaining a small car driver's license since 2013. It assesses the driver's ability to maneuver the vehicle in a confined space. Reverse parking is a key assessment point in the driver's test, requiring the driver to correctly reverse the vehicle into a garage from both sides while in motion. 2. Types: The three most common types of reverse parking are: the first is the "non"-shaped reverse parking, commonly seen in large shopping malls; the second is the roadside "one"-shaped reverse parking, also known as parallel parking; the third is the less common diagonal reverse parking.

Why can't the interior light of the Odyssey be turned off?

If the interior light of the Odyssey cannot be turned off, you can check the switch position. If the switch is in the off position, it may be a switch or circuit malfunction. Here is some extended information about interior lights: 1. Concept: Interior ambient lights are decorative lighting, usually in red, blue, green, etc., mainly to make the car more dazzling at night, enhance the atmosphere, and create an indoor mood. 2. Function: Provide interior lighting. Reading lights provide sufficient brightness for passengers when the interior light is insufficient, without affecting the driver's normal driving. Some owners forget to turn off the interior reading lights after locking the car, which may lead to battery drain and difficulty starting the car.

What are the length and width requirements for reverse parking?

Standard dimensions require the parking space width to be the vehicle width plus 60cm, and the length to be the vehicle length plus 70cm. Below is an introduction to reverse parking: 1. Overview: Reverse parking became a mandatory test item for obtaining a small vehicle driver's license after 2013. It evaluates the driver's ability to maneuver the vehicle in confined spaces. This exercise constitutes an essential assessment point in driving tests, requiring candidates to correctly reverse the vehicle into parking spaces from both sides while in motion. 2. Categories: There are three most common types of reverse parking: The first is 'non'-shaped parking (perpendicular parking), typically found in shopping malls. The second is roadside parallel parking ('I'-shaped), commonly known as parallel parking. The third is the less frequent diagonal reverse parking configuration.

Where is the starter relay located in a Citroen C-Quatre?

The relay box of the Citroen C-Quatre is located below the steering wheel on the driver's side and in the engine compartment. By carefully observing these areas, you can locate the relay box device. Due to the numerous components housed inside the Citroen C-Quatre's relay box, it tends to be large in volume and heavy in weight, making maintenance inconvenient. Consequently, the placement of the relay box also poses challenges in the overall vehicle layout. The working principle of the Citroen C-Quatre's relay is explained as follows: 1. Content one: When a certain voltage or current is applied to both ends of the electromagnetic relay coil, the magnetic flux generated by the coil passes through the magnetic circuit composed of the iron core, yoke, armature, and working air gap. Under the influence of the magnetic field, the armature is attracted to the pole face of the iron core, thereby pushing the normally closed contacts to open and the normally open contacts to close. 2. Content two: The automotive relay can be viewed as an assembly consisting of two parts: the control circuit where the coil operates and the main circuit where the contacts operate. In the control circuit of the relay, there is only a relatively small operating current. This is because the contact capacity of the operating switch is limited and cannot be used to directly control high-power loads. Instead, the relay contacts are used to control the circuit's on/off state.

Should a slightly dented subframe be replaced?

Data testing can be performed, and replacement is necessary if the data is abnormal. Below is relevant information about subframes: 1. Definition: A subframe, also known as an auxiliary frame, is not a complete frame but rather a bracket that supports the front and rear axles and suspension. It connects the axles and suspension to the "main frame" and is commonly referred to as a "subframe." The purpose of the subframe is to block vibrations and noise, reducing their direct entry into the cabin. Therefore, subframes are mostly found in luxury cars and off-road vehicles, and some vehicles even have subframes for the engine. 2. Research Progress: A type of subframe assembly includes the subframe and connecting brackets. The connecting brackets have a top surface and side surfaces, with the top surface connected below the subframe support points and the side surfaces connected to the inner side of the side flanges of the frame longitudinal beams. By positioning the connecting brackets on the side flanges of the frame longitudinal beams, the area with the highest stress—the upper flange of the frame longitudinal beam—is avoided, thereby preventing cracking issues at riveting holes caused by stress concentration and significantly improving vehicle safety.

What is the horsepower of the Yuchai 4108?

The Yuchai 4108 engine, with the Yuchai code YC4D, comes in 120 horsepower, 130 horsepower, and 140 horsepower variants. Below is some information about diesel: 1. Introduction: Diesel is a light petroleum product, a complex mixture of hydrocarbons, and serves as fuel for diesel engines. 2. Composition: Diesel is mainly produced by blending diesel fractions obtained from processes such as crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, and petroleum coking. It can also be produced from shale oil processing and coal liquefaction. 3. Types: Diesel is divided into two main categories, light diesel and heavy diesel, and is widely used in large vehicles, railway locomotives, and ships.
