1 Answers
Possible reasons for the Highlander's air conditioning not cooling include the compressor protection device tripping and circuit-related issues. Here are the specific details: High pressure or overheating: Excessive refrigerant. Appropriately reduce the refrigerant amount. Poor heat dissipation. Check the condenser pipes for dirt and clean the condenser. Blockage in the piping system. Refer to the pressure gauge for judgment, troubleshooting, and system reprocessing. Dust or scale accumulation on the evaporator or filter. Circuit-related issues: Control circuit board failure. Temperature sensor overload, incorrect information. Loose or poor contact in power wiring. Burnt-out start capacitor or compressor start coil.
