Circuit Diagram
Inspection1.Turn the ignition switch OFF.2.Disconnect the evaporator temperature sensor connector.3.Measure the resistance between terminal "+" and "-" of the evaporator temperature sensor.Specification Evaporator core temperature [°C (°F)] Resistance [KΩ]
Inspection1.Connect the battery voltage and check the blower motor rotation.2.If the blower motor does not operate well, substitute with a known-good blower motor and check for proper operation.3.Replace the blower motor if it is proved that there is a problem with it.
