The reasons for the Roewe RX5's air conditioning not being cold are: 1. Clogged air filter; 2. Damaged air conditioning compressor; 3. Slipping engine belt; 4. Lack of refrigerant. The Roewe RX5 is an SUV model under SAIC Roewe, with dimensions of 4545mm in length, 1855mm in width, and 1690mm in height, and a wheelbase of 2700mm. In terms of power, the Roewe RX5 is equipped with 1.5T and 2.0T turbocharged engines. The 1.5T engine has a maximum power of 169 horsepower and a peak torque of 250 Nm, paired with a 6-speed manual or 7-speed dual-clutch transmission. The 2.0T engine has a maximum power of 220 horsepower and a peak torque of 350 Nm, paired with a 6-speed dual-clutch transmission.
When my Roewe RX5's air conditioning isn't cooling properly, I usually start by examining daily usage habits. Driving in summer heat can be unbearable, and if the AC isn't blowing cold air, it might be due to insufficient refrigerant or leaks, resulting in poor cooling performance. Another common issue is a non-functioning compressor—you'll hear a humming noise as soon as it starts. Other problems like a broken fan, a clogged condenser with dirt, or an air filter that hasn't been replaced for too long and is packed with dust can all reduce cooling efficiency. Last time I encountered this issue, I also found a blown fuse—simply replacing it fixed the problem. I recommend regular check-ups and maintenance instead of waiting for problems to arise, as it affects driving comfort, especially during long trips where safety is crucial. Visiting a professional shop for a thorough solution is the most hassle-free approach.
When it comes to the AC not cooling properly, let me start from a system-level perspective. In the Roewe RX5, refrigerant leaks or insufficient pressure are the primary causes; decreased cooling efficiency of the compressor or internal component wear are also common issues. Fan failures leading to inadequate heat dissipation or poor electrical connections can affect overall cooling performance. I recommend regularly cleaning the air filters, as clogged filters can restrict airflow. Additionally, electrical issues such as relay burnout or voltage instability should be checked. During summer heat when parked under direct sunlight, the system bears greater stress. Timely maintenance prevents minor issues from escalating, ensuring driving safety is what truly matters.
