Owners can first perform a self-check. Inspect the circuit switch, fan switch, and fan motor for any faults; If the issue cannot be resolved on your own, it is recommended to contact a 4S shop for professional assistance.

It's really frustrating when the air conditioning in a new car has issues. I once encountered this situation and drove straight to the 4S shop. New cars are all under warranty, so don't try to fix it yourself. The mechanic said common faults include refrigerant leaks, compressor failure, or electronic control system malfunctions. After inspection, they replaced the expansion valve for free, and it took about two hours to complete. Reminder: bring your purchase invoice and warranty manual, as the 4S shop will register the vehicle information and follow the claim process. Also, here's a tip: test the air conditioning cooling effect thoroughly when you first get the car, and address any issues early. And remember to ask clearly if it affects the three-guarantee period, as some brands extend the warranty after repairs.

Last year, the air conditioning in our newly purchased car malfunctioned—it stopped cooling after three days of use. The sales consultant advised against starting the compressor to prevent further damage and recommended taking it directly to the after-sales service for inspection, especially since all components were under warranty. Common issues could be blocked pipelines or faulty temperature control sensors; in my case, it was a loose wiring connection. During repairs, remember to request a courtesy car service, which most brands offer. Also, here’s a handy tip: during maintenance, ensure they check the air filter’s installation—some new cars leave the factory with improperly installed filters, which can affect cooling. Don’t forget to take photos of the repair receipts for future reference.
