how to fix the AC not blowing cold air in my Acura MDX YF3 (2022-Present)

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Disconnect the battery to prevent electrical shorts while working on the AC system.

2. Recharge Refrigerant

• Tools Required: Manifold gauge set, refrigerant canister, and hose.
• Connect the low-pressure side of the manifold gauge to the AC service port.
• Start the engine and turn on the AC to the coldest setting.
• Check the pressure readings; if low, add refrigerant according to the manufacturer's specifications.
• Monitor the gauge while adding refrigerant until the correct pressure is achieved.

3. Inspect and Replace AC Components

• Tools Required: Socket set, screwdrivers, and wrenches.
• If the compressor does not engage, check the electrical connections and replace any damaged wires.
• If the AC compressor is faulty, detach the compressor from the mounting brackets and disconnect the refrigerant lines.
• Install the new compressor, tightening bolts to the manufacturer’s torque specifications.

4. Replace Cabin Air Filter

• Tools Required: Screwdriver.
• Locate the cabin air filter compartment, usually behind the glove box.
• Remove the glove box if necessary to access the filter.
• Replace the old cabin air filter with a new one, ensuring it is oriented correctly.

5. Test the AC System

• Reconnect the battery and start the vehicle.
• Set the AC to the coldest setting and allow it to run for a few minutes.
• Monitor the temperature of the air blowing from the vents to ensure it is cold.
