Why is my Lexus AC not blowing air?

Possible Causes for Lexus AC Not Blowing Air
There could be several reasons why your Lexus AC is not blowing air. Here are some possible causes based on the search results:
1. Malfunctioning Servo Motor: One possible cause is a faulty servo motor, specifically the MODE door servo. This servo motor is responsible for controlling the direction of airflow in the HVAC system. If it is not functioning properly, it may prevent air from blowing out of the center vents.
2. Clogged Drain Line or Low Refrigerant: Another potential cause is a clogged drain line or low refrigerant levels. A clogged drain line can lead to water accumulation and affect the performance of the AC system. Low refrigerant levels can result in reduced cooling capacity. It is recommended to check the drain line for any blockages and inspect the compressor and sight gauge for potential issues.
3. Leak in the AC System: A leak in the AC system can also cause the AC to stop blowing cold air. If there is a leak, the system needs to be evacuated, recharged with dye, and checked for leaks using a special light.
4. Issues with the Servo Motor Position: In some cases, the servo motor may not be returning to the correct position when adjusting the temperature. This can result in the AC blowing hot air on the passenger side. Resetting the AC using Techstream or having the servo motor replaced may be necessary.
It is important to note that these are potential causes based on the search results. To accurately diagnose and resolve the issue, it is recommended to consult a qualified mechanic or contact a Lexus dealership for assistance.
