Problem overview

Some Subaru Forester owners report experiencing issues with their A/C not working and the compressor failing to activate after winter. These problems may stem from low refrigerant levels, which can impede the compressor's operation. Additionally, a faulty compressor is a common concern among owners, potentially requiring replacement if it malfunctions. Some owners also find that a clogged expansion valve disrupts the proper flow of refrigerant through the system. Furthermore, electrical problems, such as damaged fuses, relays, or wiring, can prevent the compressor from engaging. To address these issues, it is recommended to check refrigerant levels, inspect the compressor for damage, verify the clutch engagement, and ensure the A/C relay is functioning correctly. If problems persist after these troubleshooting steps, seeking professional assistance is advisable.
