How to modify the Focus air conditioner if it is not cool?

The poor cooling effect of the air conditioner is usually caused by a malfunction and does not necessarily require modification.

Common fault points of poor air conditioning cooling effect include:

The refrigerant in the air conditioning system leaks completely, resulting in no refrigerant, so the air conditioner stops cooling.

1. You can check whether the pipelines, air conditioning pumps, condensers, evaporation boxes and other components in the air conditioning system are damaged, causing refrigerant leakage. Another inspection method can be to add fluorescent agent while adding refrigerant. After using the vehicle for a week, use a special fluorescent light to check the air conditioning system. If there is a leakage point that will light up, it means that this component is damaged.

2. The air-conditioning pump is damaged internally, resulting in the inability to start the cooling effect. Generally, abnormal noise will occur when the air-conditioning pump is damaged. So check the air conditioning pump and replace it if it is damaged.
