Lexus RX Air Conditioning Service
- RX 350 belt-driven compressor: V6 compressor driven by accessory belt — inspect belt tension at every service; RX 450h uses electric compressor driven by HV battery — no belt
- RX family SUV A/C demand: 7-seater RX L and standard 5-seater; 3-row RX L has extended rear A/C ducts — inspect rear duct connections and rear A/C vents for obstruction if rear passengers report weak cooling
- RX A/C regas: large SUV cabin volume — refrigerant charge is higher than sedan; regas every 3 years; UV dye leak test recommended before regas if cooling was gradually declining
- RX condenser: large SUV condenser — inspect for fin damage from road debris; bent fins reduce airflow and cause A/C pressure issues; straighten fins with fin comb or replace condenser if severely damaged
