Chrysler PT Cruiser heating issue with fan running continuously and inconsistent heat production on Chrysler PT Cruiser

Some Chrysler PT Cruiser owners report experiencing issues with continuous fan operation, which may be due to wiring modifications that cause the fan to run constantly, affecting engine temperature regulation. This can lead to inconsistent heat production inside the vehicle, particularly noted in model years like 2004 and 2010. Additionally, overheating problems are reported, stemming from coolant leaks, radiator fan malfunctions, failed thermostats, or clogged radiators, which can cause the engine to overheat during idle or low-speed situations. Common causes of radiator fan malfunctions include issues with the fan assembly, fan clutch, or coolant temperature sensor. Furthermore, some owners find that air trapped in the cooling system can hinder performance and contribute to overheating. To address these heating issues, it is recommended that owners check the fan wiring, inspect cooling system components, and ensure proper bleeding of the system. If problems persist, consulting a qualified technician may be necessary for effective diagnosis and resolution.
