- If the air conditioning system is low on refrigerant, the evaporator coil will not be able to absorb enough heat from the air, resulting in warm air blowing from the vents.
Compressor issues:
- The air conditioner compressor is the heart of the cooling system. If the compressor is not functioning properly, it will not be able to properly compress the refrigerant and circulate it through the system, resulting in warm air blowing from the vents.
Faulty expansion valve:
The expansion valve regulates the flow of refrigerant into the evaporator coil. If the expansion valve is not functioning properly, it can cause the evaporator coil to become too cold or too hot, resulting in warm air blowing from the vents.
Blocked air vents:
- If the air vents are blocked, the airflow to the evaporator coil will be restricted, preventing it from absorbing heat from the air. This can result in warm air blowing from the vents.
Electrical problems:
- Electrical issues, such as a faulty wiring or a blown fuse, can also prevent the air conditioner from working properly.
If you have already recharged the system and the air conditioner worked for a little while, but then stopped blowing cold air again, it is likely that one of these issues is the cause. It would be best to have your vehicle inspected by a qualified mechanic who can properly diagnose and repair the problem.
