What is the reason for the car's air conditioning not cooling after passing through a puddle?

It may be due to excessive refrigerant, which leads to a decrease in cooling efficiency. The refrigerant and refrigeration oil contain too many impurities, causing slight blockages and resulting in insufficient cooling capacity. Here is some relevant information: 1. Introduction: Freon is a common refrigerant, with many types, such as R22, R32, R134a, etc. Freon is generally a gas at normal temperature and pressure, with a slight aromatic odor. Under low temperature and high pressure, it appears as a transparent liquid. It can mix with halogenated hydrocarbons, monohydric alcohols, or other organic solvents in any proportion, and different types of Freon can also mix with each other. Due to its strong chemical stability, thermal stability, low surface tension, easy phase change between gas and liquid, non-toxicity, oil affinity, and low cost, Freon is widely used in industries such as refrigeration, foaming, solvents, sprays, and cleaning of electronic components. 2. Classification: Freon is roughly divided into three categories, including chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and hydrofluorocarbons (HFCs).
After driving through a puddle, the car's AC isn't cooling properly. I suspect mud and water might have clogged the AC condenser. Located at the front of the car, the condenser is responsible for heat dissipation. When splashed with mud, its cooling efficiency drops instantly due to poor heat dissipation. Another common issue is that water impact may cause electrical shorts or moisture damage, such as a malfunctioning AC fan sensor that automatically shuts off the fan. Additionally, the compressor might have been waterlogged and stopped working, or the refrigerant lines could have loosened and leaked. It’s as frustrating as a broken fan after a summer run. After parking, try rinsing the condenser first to see if it helps. If not, visit a professional shop to check the electrical system. When driving through water, slow down and brake early to minimize these issues. Don’t overlook regular car washing and maintenance to extend your AC's lifespan.
