What causes the Highlander's air conditioning to not cool?
1 Answers
Possible reasons for the Highlander's air conditioning not cooling include the compressor protection device tripping and electrical circuit issues. Here are the specific details: 1. High pressure or overheating: Excessive refrigerant. Appropriately reduce the refrigerant amount. Poor heat dissipation. Check if the condenser tube has dust buildup and clean the condenser. Blockage in the pipeline system. Refer to the pressure gauge for judgment, troubleshooting, and re-system processing. Dust accumulation or scaling on the evaporator or filter. 2. Electrical circuit issues include: Control circuit board failure. Temperature sensor overload, incorrect information. Loose power wiring, poor contact. Start capacitor or compressor start coil burned out.
