What is the reason for the Honda CR-V air conditioning not working?
3 Answers
The reasons for the air conditioning not working are as follows: 1. Air in the air conditioning system: Once air enters the air conditioning system, it will cause excessive pressure in the refrigerant pipes, and poor refrigerant circulation will also lead to insufficient cooling. This type of fault is mainly due to the deterioration of the sealing of the refrigeration system or incomplete vacuuming during maintenance. 2. Excessive refrigerant causing insufficient cooling: Excessive refrigerant is usually caused by overcharging during maintenance, as there is a certain requirement for the proportion of refrigerant volume in the air conditioning system. If the proportion is too high, it will affect the heat dissipation, meaning more heat dissipation results in greater cooling capacity; conversely, less heat dissipation results in smaller cooling capacity. Similarly, if too much cooling oil is added during maintenance, it will also reduce the heat dissipation of the refrigeration system.
My Honda CRV's air conditioning suddenly stopped cooling the other day. At first, I thought it was due to the high summer temperatures, but after checking, there turned out to be multiple issues. The most common problems are low or leaking refrigerant, or system degradation from prolonged use, which reduces cooling efficiency. Checking the AC compressor is also crucial—if it fails, there will be no cold air output. Electrical issues, such as blown fuses, faulty relays, or poor switch contact, can also cause the AC to stop working. Remember to inspect the engine compartment’s fuse box, as some CRV models are prone to issues in this area. Another common issue is the fan not spinning, especially if the condenser fan is damaged, which affects heat dissipation. I recommend not attempting DIY fixes, especially for pipeline-related problems, as improper handling could cause further damage. It’s best to visit a 4S shop or a professional repair center promptly—they have the tools for proper diagnostics. Driving without AC in summer is unbearable; opening the windows leads to loud wind noise and unbearable heat, even causing dizziness. Regular maintenance can help prevent such issues.
When my CRV's air conditioning stopped working, I initially thought it was due to the weather. Later, I realized it might be because the fan motor was broken, leading to poor air circulation, or there could be a refrigerant leak causing a drop in system pressure. Electrical issues like a blown fuse are the easiest to check—just look under the dashboard. If the compressor doesn’t start, there will be no cold air at all, and sometimes it’s due to a worn-out belt. When inspecting it yourself, pay attention to unusual smells or noises as clues, but avoid disassembling parts to prevent accidental damage. It’s best to visit a professional shop for a quick diagnosis. My friend’s car had a similar issue, and delaying repairs led to circuit damage, doubling the repair cost. Driving without AC in hot weather affects both mood and comfort, so proactive maintenance saves hassle.
