Lexus LS Air Conditioning Service
- LS 460 A/C: belt-driven compressor on V8; LS 600h hybrid uses electric compressor — quiet operation befitting flagship sedan; rear passengers get dedicated rear climate zones with individual controls
- LS rear seat A/C: LS rear passengers can control their own temperature — rear blower motor, rear evaporator, and rear expansion valve are separate components; rear A/C diagnosis requires specific Techstream testing
- LS A/C regas: flagship sedan with premium climate system — use OEM-spec refrigerant and PAG oil; regas every 3 years; any reduction in cooling performance should be investigated with UV dye leak test before regas
- LS evaporator odour: LS rear and front evaporators both prone to mould in Malaysia humidity — annual antibacterial fumigation with A/C cleaner recommended; keep cabin filter fresh for LS's premium interior air quality
