Car air conditioner has no wind in gears 1-3 but works normally in gear 4 due to a blower motor resistor failure. Here are the relevant explanations: Purpose: When using the air conditioner in summer, parked vehicles should first open the windows, set the blower to the highest gear, allow air convection inside the car to expel hot air quickly, then close the windows for rapid cooling. Starting load: When parking, turn off the air conditioner before shutting down the engine to avoid increasing the starting load. Internal circulation: Turn on internal circulation when using the air conditioner for optimal cooling effect. Long-term use of air conditioner: Avoid prolonged use of the air conditioner when the vehicle is parked to prevent deterioration of air quality inside the car, which may affect health.
