What Causes a Car's Air Conditioning to Blow Air After a Few Minutes Delay?

[DelHector]

Car air conditioning blowing air after a few minutes delay may indicate an issue with the resistor. Here are some important considerations regarding car air conditioning: 1. Select the appropriate fan speed setting: During normal vehicle operation, to prevent excessive frosting on the evaporator which could affect the air conditioning system's performance, the air delivery speed and temperature control should not be operated simultaneously. When driving below 25km/h, set the fan speed to the low setting to avoid insufficient power generation and inadequate cooling. 2. Adjust air vent direction: Following the principle that cold air sinks while warm air rises, the correct adjustment method is to direct the vents upward when using cooling mode and downward when using heating mode. 3. Regular winter activation: In regions with relatively warm winters such as Guangdong and Hainan, some car owners don't use their air conditioning throughout winter. Prolonged disuse can cause rubber seals to deteriorate and internal lubricants to dry out. Periodic activation allows components to receive proper lubrication and maintain good condition. Therefore, it's recommended to run the air conditioning every 1-3 weeks during winter.
