FUNCTIONAL TEST
Before beginning the functional test of the heater system, the engine must be idling with the coolant hot and thermostat open. Coolant temperature must be about 90°C (194°F). During the function test, evaluate the operating efforts of the mode control knob and the temperature control knob. Even if a problem is found during any intermediate step of the function test, the test should be completed before repair is started (refer to accompanying figures).
