Why is my Lexus SC430 AC not blowing cold air?

Possible Reasons for Lexus SC430 AC Not Blowing Cold Air
There are several potential reasons why your Lexus SC430’s AC may not be blowing cold air. Here are some possibilities based on the information from the search results:
1. Refrigerant Leak: Over time, refrigerant can leak from the AC system through seals. If the AC does not have enough refrigerant, it will not blow cold air.
2. Malfunctioning Compressor Clutch: An AC system that starts off blowing cold air but then turns warm can mean there’s a malfunctioning compressor clutch.
3. Issues with Expansion Valve and Dryer: It’s recommended to change the expansion valve and dryer whenever the system is opened to prevent issues like leaking.
4. Damaged Servo Motor: If the AC is not blowing from the center vents, it’s possible that the MODE door servo, located on the passenger side of the car, may be bad.
Recommendations
Based on the potential reasons mentioned above, here are some recommendations to address the issue:
– Have a mechanic check for a refrigerant leak and recharge the system if necessary.
– Get the compressor clutch inspected and repaired if it’s malfunctioning.
– Consider having the expansion valve and dryer changed to prevent potential issues.
