Chrysler PT Cruiser overheating issue with fan not activating and loud compressor noise when AC is turned on on Chrysler PT Cruiser

Some Chrysler PT Cruiser owners report experiencing overheating issues due to the radiator fan not activating and a loud compressor noise when the AC is turned on. Common causes for the fan not working include problems with the fan assembly, fan clutch, or the coolant temperature sensor. Additionally, a loud compressor noise may indicate issues with the AC compressor itself. Owners are advised to check for debris between the condenser and the fan, as well as ensure the fan is functioning properly. If the AC is on and the fan is not running, especially at high speed, this could suggest a malfunction in the fan's high-speed function. Checking the relays mounted on the fan and monitoring coolant levels are also important steps, as inadequate coolant can contribute to overheating. Prompt inspection and diagnosis of these components are crucial for effective resolution of these issues.
