REFRIGERANT SYSTEM TESTS1. Connect an A/C recovery and/or charging station with gauges or Connect an R134a manifold gauge set to the refrigerant system.
2. Set the climate control system to MAX A/C (if equipped), or select A/C and RECIRC (if equipped), at HI blower.
3. Run the engine at 1500 rpm for 10 minutes.
NOTE: When the ambient temperature exceeds 38°C (100°F), do not run the engine above normal idle speed.
4. Stabilize the vehicle interior temperature at 21°C to 27°C (70°F to 80°F).
