Diagnosis With GDS 1. The heating, ventilation and air conditioning can be quickly diagnosed failed parts with vehicle diagnostic system (GDS). ※ The diagnostic system (GDS) provides the following information.
Inspection 1. Measure the resistance between the terminals. 2. The measured resistance is not within specification, the blower resistor must be replaced. (After removing the resistor) Replacement 1.
