Q: AC not working

asked by on

The AC in my car is not running cold.

Hi there. The a/c compressor suction manifold hose may be defective and might be leaking where it seals on the compressor. The manufacturer has issued a technical bulletin to replace these leaking hoses, no matter the mileage, on the affected vehicles. This means they made a defective part and should replace it at no charge. I recommend you have a mechanic, like one from YourMechanic, inspect your AC and figure out where the leak begins. After the leak is diagnosed, you could see if the dealer will replace it for free, otherwise, YourMechanic can do it for you.
