What is the reason for the Passat's air conditioning not cooling?
2 Answers
Passat's air conditioning not cooling may be due to a lack of refrigerant or a malfunction in the compressor or heat exchanger. Here is a detailed introduction about the Passat: Overview: The Passat (PASSAT) is a mid-sized sedan designed by Volkswagen in Germany. In the Volkswagen lineup, it is classified as a B-segment car. The Passat has been in production since 1973. Features: With the Passat, the application of the most advanced engineering technology has allowed the sedan to surpass the standard design of mid-range cars in terms of power performance, overall design, safety concepts, driving comfort, durability, and reliability.
I've been driving a Passat, and last summer the air conditioning suddenly stopped cooling, making the car as hot as a steamer, which easily leads to fatigue driving and accidents. The reason is mostly due to refrigerant leakage—even a tiny bit less and the AC stops working, or the compressor gets stuck and won't run. That time, I found a small crack in the pipe during inspection—the rubber had aged due to the extreme heat. Other possible causes include a broken fan, a blown fuse, or poor contact in the AC switch. It's recommended to first pop the hood and check if there's any air leakage by feeling the AC pipes. If that doesn't help, head to a repair shop immediately. Before driving in summer, test the AC to identify issues early and avoid problems on the road.
