• Disconnect the vehicle's battery to ensure safety during repairs.

2. Check and Recharge Refrigerant

• Tools Required: Refrigerant gauge set, refrigerant
• Verify the refrigerant level using the gauge set.

• Monitor the pressures to ensure they are within the normal operating range.

3. Inspect and Replace AC Compressor (if necessary)

• Tools Required: Socket set, torque wrench, AC compressor removal tool
• Remove the drive belt from the AC compressor.
• Disconnect the electrical connectors and refrigerant lines from the compressor.
• Unbolt and remove the compressor from its mounting bracket.

4. Check and Replace Cabin Air Filter

• Tools Required: None, but a flat-head screwdriver may be needed for some models.
• Locate the cabin air filter compartment, usually behind the glove box.
• Remove the old filter and inspect for dirt or clogs.
• Install a new cabin air filter, ensuring it is seated correctly.

5. Reconnect Battery and Test

• Reconnect the vehicle's battery.
• Start the engine and turn on the AC to the maximum setting.
