Why does the BMW car's air conditioner not respond when turned on?
1 Answers
When the BMW car's air conditioner is turned on and there is no response, it may be due to a lack of refrigerant, a dirty condenser, or water in the pipeline. Below are the detailed explanations for these causes. Lack of Refrigerant: The loss of refrigerant is mostly due to leakage. If the car's air conditioner is not working properly and the issue recurs after refilling the refrigerant, it is important to pay attention. A relatively simple method to detect leakage is to observe the condenser surface through the grille for signs of oil wetting. If such a condition is present, it usually indicates a leakage in the condenser. Dirty Condenser: During summer, it is common to find the air conditioner not working properly. When visiting a 4S shop for repairs, the owner is often recommended to clean the radiator. The purpose of cleaning the radiator and condenser is mainly for heat dissipation. If poplar or willow catkins accumulate on the condenser, it can lead to phenomena such as excessive engine temperature or poor air conditioning performance. During cleaning, it is crucial to first use an air gun to blow away the debris before washing with a water gun. Otherwise, it may have the opposite effect, not only causing poor air conditioning performance but also increasing fuel consumption. Water in the Pipeline: There is a dryer in the car's air conditioning 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. This phenomenon can lead to poor refrigerant flow, increased resistance, and ultimately result in the air conditioner failing to cool.
