Abstract

The air conditioning (AC) system in a vehicle is a crucial component, especially in cars. Its primary task is to ensure the comfort of the driver and passengers. This system requires monitoring and maintenance for long-term use. This also applies to the AC system in Avanza/Xenia vehicles. Maintenance and repairs are ways to address issues that may weaken or damage your vehicle's AC system. Of course, maintenance and repair procedures should be carried out in accordance with proper troubleshooting rules. Troubleshooting involves a process known as diagnosis, which is the step to identify signs of damage and schedule investigations to resolve existing problems. Inspections involve using measuring tools such as a compressor and a multimeter on the magnetic clutch and evaporator to check the main components of the AC system. This is done to determine whether these components are operating properly according to service and maintenance standards for vehicle AC systems. Upon identification, corrective actions can be taken. The results show that the resistance value of the magnetic clutch coil is 3.9 ohms, and the magnetic clutch gap is 0.5 mm. The blower system resistance with three speed variations is 2.6 ohms at the low position, 0.7 ohms at the middle position, and 0 ohms at the high position. The blower motor resistance is 4 ohms. The measured values fall within the service limits or normal range as per the Avanza/Xenia manual. Therefore, it can be concluded that there are no issues with the AC system in the Avanza/Xenia vehicle, and the condition of the AC system is normal and suitable for use. No repair procedures are required, only routine maintenance is performed to ensure all components are in good condition.

Highlights:

• Routine maintenance prolongs AC system lifespan.


• Accurate diagnosis prevents potential issues.


• Component inspection ensures system health.
