What is the reason for the front of the car air conditioner not cooling while the rear is cooling?

Introduction to the reasons why the front of the car air conditioner does not cool while the rear does: 1. Lack of refrigerant: The loss of refrigerant is mainly due to leakage. If the car's air conditioner is not working properly and starts malfunctioning again after adding refrigerant for a period of time, a relatively simple method is applicable when leakage occurs. You can see oil stains on the surface of the condenser through the grille. When this happens, it usually indicates a leakage in the condenser. 2. Dirty condenser: When cleaning, be sure to first use an air gun to blow it clean, then wash it with a water gun, otherwise it will have the opposite effect. Not only will the air conditioner not work properly, but fuel consumption will also increase. 3. Water in the pipeline: There is a dryer in the car air conditioner's refrigeration system, whose task is to absorb moisture from the refrigerant. When the desiccant in the dryer is saturated, moisture can no longer be filtered out. When the refrigerant passes through the expansion valve orifice, its pressure and temperature drop, causing the water in the refrigerant to freeze in the small hole, leading to poor refrigerant flow, increased resistance, and the air conditioner's inability to cool.
