how to fix the AC not blowing cold air in my Toyota RAV4 XA50 (2019-2024)

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Ensure the vehicle is parked on level ground, and the engine is turned off.
• Disconnect the battery to prevent electrical shocks.

2. Recharge Refrigerant

• Tools Required: Manifold gauge set, refrigerant canister, safety glasses, gloves.
• Attach the manifold gauge set to the AC service ports (low and high side).
• Open the low-pressure valve and check the pressure readings.
• If low, connect a refrigerant canister to the low-pressure side of the manifold.
• Slowly add refrigerant according to the manufacturer's specifications until the proper pressure is reached.
• Monitor the gauge while adding refrigerant to avoid overfilling.

3. Repair AC Compressor (if necessary)

• Tools Required: Socket set, torque wrench, refrigerant oil, new compressor, A/C belt (if damaged).
• If the compressor is faulty, remove the drive belt by loosening the tensioner pulley.
• Disconnect the electrical connector and refrigerant lines from the compressor.
• Remove the mounting bolts and take out the old compressor.
• Install the new compressor, ensuring proper alignment and torque specifications.
• Reconnect the refrigerant lines and electrical connectors.

4. Replace Cabin Air Filter (if dirty)

• Tools Required: None needed for this step.
• Locate the cabin air filter housing (usually behind the glove box).
• Open the glove box and remove any clips or stops holding it in place.
• Take out the old cabin air filter and clean the housing area if necessary.
• Insert the new cabin air filter in the correct orientation.

5. Finalize Installation

• Reconnect the battery.
• Start the engine and turn on the AC to the maximum setting.
• Allow the system to run for a few minutes to stabilize the refrigerant levels.
