Buick Excelle fan keeps running continuously due to a loose circuit connection. Below are the reasons and solutions for the Buick Excelle fan running continuously: 1. Loose circuit connection. Solution: Try unplugging the fan's wiring harness and perform a separate power cut. This situation could also be caused by a faulty water temperature sensor or a stuck fan relay contact. It is recommended to visit a 4S shop or a professional repair shop to replace it with a new one. 2. Cooling: The fan inside the car serves a cooling function. Solution: When the car is parked and the coolant temperature is too high, the onboard computer will automatically calculate the fan's speed and duration. Therefore, the higher the temperature, the longer the fan runs to protect the engine. This is a normal phenomenon, so there is no need to worry.

I previously drove a Buick Excelle, and the issue of the fan running non-stop is mostly caused by several reasons. The fan running continuously is usually for cooling, but if it doesn't stop after parking, it might be an electrical fault. First, check if the temperature control sensor is faulty because incorrect temperature readings can cause the fan to run unnecessarily. A stuck relay is also a common issue—look for the relay in the fuse box under the hood, feel if it's hot, and try manually resetting it. Problems with the cooling system, such as low coolant levels, leaks, or a dirty radiator, can cause the engine to overheat, making the fan work overtime. Electrical issues like wiring shorts or an aging fan controller can also lead to this situation. Remember to check promptly to avoid draining the battery and being unable to start the car. It's best to visit a 4S店 or repair shop to read the fault codes with a computer to confirm the root cause and ensure safety. Regular maintenance of the cooling system can prevent such troubles.

As a car enthusiast, I often fix the issue of the Buick Excelle's fan running continuously myself. The most likely cause is a faulty temperature sensor, making the fan think the engine is still hot and thus keeps running, or the fan relay might be stuck in the on position—try tapping it to release. Insufficient coolant or a clogged radiator causing the engine to actually overheat will naturally make the fan run, and if the air conditioning is on, the fan will also work for cooling. Checking the fuses and whether the circuit has power can help determine if it's a short circuit issue. I recommend replacing small parts like a new relay yourself to save money and effort, but don’t delay too long to avoid engine damage from overheating, which could affect driving safety.

What does downgraded car mean?

Downgraded cars are internal road test vehicles from automobile manufacturers, also known as damaged quality vehicles. Definition of inventory cars: Vehicles that have been in stock for a long time. The classification of inventory cars varies widely; those exceeding three months or half a year can be called inventory cars. The definition differs for each brand and dealership. Types of damaged quality vehicles: Damaged quality vehicles generally fall into two categories. One type is vehicles damaged during logistics. For minor scratches and bumps, dealers repair them and sell them as regular vehicles. The damaged quality here usually refers to those that have undergone major repairs. The other type consists of vehicles used in manufacturer test drive events. Dealers typically handle damaged quality vehicles through internal processing or sell them at discounted prices.

What does 100 mph mean?

100 mph = 100 miles = 100 km/h = 100 kilometers per hour. Driving speed: There are two ways to express the driving speed of a car, one is "kilometers per hour (Km/h)", and the other is "miles per hour (MPH)". Generally, Japanese and Korean car models and most European car models are accustomed to using "kilometers per hour" to indicate speed, while the North American market usually uses "miles per hour" to indicate speed. As for domestic car models, including most imported models, they all use "kilometers per hour" to indicate speed. Origin of the term "mph": The common saying of how many mph a car is going originates from the speed unit "mile". Originally, one mile equaled 1 mile per hour, which is approximately equal to 1.6 kilometers per hour when converted to the metric system. Later, the metric system became internationally common.

What is NEDC Combined Fuel Consumption?

NEDC combined fuel consumption serves as China's reference standard for testing the driving range of electric vehicles. The NEDC test cycle consists of two parts: ECE (Urban Driving Cycle) and EUDC (Extra-Urban Driving Cycle). Purpose of ECE: It simulates traditional urban road conditions, composed of four ECE15 cycles. Each ECE15 cycle includes 15 driving conditions such as acceleration, deceleration, constant speed, and idling. The ECE cycle lasts for 780 seconds, covers a total distance of 4.052 km, with an average speed of 18.7 km/h, characterized by low speed, low load, and low exhaust temperature. Purpose of EUDC: EUDC simulates suburban road conditions, lasting for 400 seconds, covering a distance of 6.955 km, with an average speed of 62.6 km/h. The maximum speed in this segment reaches 120 km/h.
