a Content Block 1: Bus Air Conditioner Overheating – Reduced Cooling System Efficiency – The Direct Root Cause of Overheating Problems Problem Status: As the main heat dissipation component, the condenser, due to surface contamination (catkins, insect remains, dust), fan malfunction (not rotating, insufficient speed), or poor ventilation in its installation location, prevents the high-temperature, […]
Bus AC not blowing air is a common but directly impactful malfunction, involving multiple subsystems including power, control, mechanics, and operation. An article titled “Failure Mode Analysis of Commercial Vehicle HVAC Air Supply System,” published in the 12th issue of the *China Transportation Equipment Technology Journal* in 2025, points out that “approximately 70% of ‘no […]
Analysis and Solutions to Bus AC Pressure Problems The stable operation of the bus air conditioning system is directly related to passenger comfort and driving safety. Abnormal pressure is a comprehensive fault signal, often involving multiple subsystems. This article draws on the research framework of the article “Fault Modal Analysis of Thermal Management System for […]
Bus AC fan not working will directly cause air conditioning failure and may trigger a chain reaction of problems such as high system pressure and compressor damage. The bus air conditioning fan (including the condenser fan and evaporator blower) is a core component ensuring heat exchange efficiency, cooling effect, and system safety. The first issue […]
