- This is the most common cause of uneven cooling in a car’s air conditioning system.
- When the refrigerant level is low, the system cannot absorb heat from the passenger compartment efficiently, resulting in warm air blowing on the driver’s side.
2. Faulty temperature blend door:
- The temperature blend door is a valve that controls the mix of hot and cold air that flows into the passenger compartment.
- If the blend door is stuck or malfunctioning, it can cause warm air to flow into the driver’s side, even when the air conditioner is turned on.
3. Clogged evaporator core:
- The evaporator core is a component of the air conditioning system that absorbs heat from the air.
- If the evaporator core is clogged with dirt or debris, it can restrict airflow and reduce the system’s cooling capacity, resulting in warm air blowing on the driver’s side.
4. Faulty expansion valve:
- The expansion valve controls the flow of refrigerant into the evaporator core.
- If the expansion valve is faulty, it can cause too much or too little refrigerant to flow into the evaporator core, resulting in uneven cooling.
5. Air leaks:
- Air leaks in the air conditioning system can also cause uneven cooling.
- Leaks can allow warm air to enter the system, which can mix with the cold air and result in warm air blowing on the driver’s side.
If you are experiencing uneven cooling in your car’s air conditioning system, it is important to have the system inspected by a qualified mechanic as soon as possible. Ignoring the problem can lead to further damage to the system and more expensive repairs.
