There are several main reasons why a car's air conditioning may not blow air: Blower motor failure: As the core component responsible for air output, a malfunctioning blower motor will definitely result in no airflow. Possible causes of blower motor failure include overheating damage to internal coils or capacitor failure. Owners can diagnose this issue by turning the air conditioning fan speed to maximum and listening for blower motor operation. Clogged cabin air filter: This represents the most common cause of no airflow. The cabin air filter purifies outside air before it enters the vehicle interior, but also accumulates various airborne particles, making it prone to clogging. The filter can be removed for inspection - if not excessively dirty, cleaning it with compressed air and reinstalling may resolve the vent airflow issue.

What Are the Reasons for Slow Engine Coolant Temperature Rise?

Engine coolant temperature rises slowly due to a damaged thermostat that fails to close or a malfunctioning cooling fan that runs continuously. When the thermostat valve fails to close, the coolant continuously circulates through the large loop, causing the car's coolant temperature to drop rapidly. If the cooling fan malfunctions and keeps running, it will result in lower engine coolant temperature. The function of the engine is to convert the thermal energy of gasoline or diesel into mechanical energy by burning the fuel in a sealed cylinder, which expands the gas and pushes the piston to perform work. Methods for engine maintenance include: 1. Using qualified engine oil; 2. Using qualified coolant and antifreeze; 3. Regularly cleaning the radiator scale; 4. Regularly removing engine carbon deposits; 5. Regularly replacing the car's three filters (air, oil, and fuel filters); 6. Maintaining a reasonable engine speed.
