why does my Volvo XC60 Second Generation (2018-2024) AC blow warm air

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Ensure the vehicle is parked on a level surface and the ignition is off.
• Disconnect the negative battery terminal to avoid electrical hazards.

2. Recharge the AC System

• Tools Required: AC refrigerant gauge, R-134a refrigerant.
• Sub-steps:
  1. Connect the AC refrigerant gauge to the low-pressure service port.
  2. Start the engine and turn the AC to maximum cool.
  3. Check the pressure reading; if low, proceed to add refrigerant.
  4. Add R-134a refrigerant slowly while monitoring the pressure gauge until it reaches the manufacturer's recommended level.
  5. Disconnect the gauge and reconnect the battery terminal.

3. Replace the Cabin Air Filter

• Tools Required: Screwdriver or trim removal tool.
• Sub-steps:
  1. Locate the cabin air filter access panel, usually found behind the glove compartment.
  2. Remove the screws or clips securing the access panel and gently pull it off.
  3. Take out the old cabin air filter and inspect it for dirt and debris.
  4. Insert the new cabin air filter in the correct orientation.
  5. Reattach the access panel and secure it with screws or clips.

4. Inspect and Replace the AC Compressor (if necessary)

• Tools Required: Socket set, torque wrench, refrigerant recovery machine (if replacing).
• Sub-steps:
  1. Recover the refrigerant from the system using the refrigerant recovery machine.
  2. Disconnect the AC compressor electrical connector and the refrigerant lines.
  3. Remove the mounting bolts from the compressor and carefully take it out.
  4. Install the new compressor by reversing the removal steps.
  5. Reconnect the refrigerant lines and electrical connector, ensuring all seals are intact.
  6. Recharge the AC system with refrigerant as outlined in Step 2.
