How to Solve the Issue of Unable to Activate Temperature Control in Model 3?

[VanAlexa]

The reasons and solutions for the inability to activate temperature control in Model 3 are as follows: 1. Complete Refrigerant Leakage: It is necessary to identify the leakage point (such as worn-out pipelines, ruptured pipeline sealing rings, damaged condenser tubes, loose or untightened pressure switches, damaged and leaking expansion valves, or failed compressor safety discs). After replacing the failed components, refill the refrigerant according to the specified amount for the air conditioning system to resolve the issue. 2. Worn-out Expansion Valve Temperature Sensor: A worn-out expansion valve temperature sensor causes the compressor to engage without cooling the air conditioning system. The surface temperature of the compressor discharge pipe becomes very high, and there is no temperature difference between the inlet and outlet pipes of the expansion valve. After the compressor engages, the high pressure remains unchanged, but the low pressure is very low. In this case, replace the expansion valve and refill the refrigerant according to the specified amount for the air conditioning system to resolve the issue.
