Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface.
• Disconnect the battery to prevent electrical issues.

2. Recover Refrigerant

• Use a refrigerant recovery machine to safely remove refrigerant from the system.
• Follow the machine’s instructions to ensure proper recovery.

3. Inspect and Replace Components

• Check AC Compressor:

  • Inspect the compressor for any physical damage.
  • If damaged, remove the compressor using a socket set (torque bolts to manufacturer specifications).
  • Replace with a new compressor if necessary.

• Recharge Refrigerant:

  • Connect the gauge set to the low and high-pressure ports of the AC system.
  • Use the appropriate refrigerant as specified by Toyota (typically R-134a or R-1234yf).
  • Follow the manufacturer’s guidelines for the correct amount of refrigerant.

4. Replace Cabin Air Filter

• Open the glove compartment and remove it to access the cabin air filter.
• Replace with a new filter, ensuring it is oriented correctly.

5. Test System Operation

• Reconnect the battery.
• Start the engine and turn on the AC to the max setting.
• Monitor the temperature of the air blowing from the vents.
