What causes the air conditioning in a 2013 Mondeo to not cool?
1 Answers
Reasons why a car's air conditioning may not cool include: insufficient refrigerant, a dirty condenser, or water in the pipes. Below are the relevant explanations: Insufficient refrigerant: Refrigerant loss is mainly due to leaks. If the car's air conditioning is not working well and becomes ineffective again after refilling the refrigerant for a period of time, it should be noted. A relatively simple method applies when there is a leak: you can see oil stains on the surface of the condenser through the grille. When this happens, it usually indicates a leak in the condenser. Dirty condenser: In summer, it is often found that the air conditioning is not working well. When going to 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. When poplar and willow catkins accumulate on the condenser, it can cause issues such as excessively high engine temperature or poor air conditioning. When cleaning, be sure to first use an air gun to blow them clean, then wash with a water gun; otherwise, it may have the opposite effect, not only causing poor air conditioning but also increasing fuel consumption. Water in the pipes: There is a dryer in the car 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, leading to poor refrigerant flow, increased resistance, and ultimately the air conditioning not cooling.
