why is my Toyota Tacoma N300 (2016-Present) AC blowing hot air

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to ensure safety while working on electrical components.

2. Recharge Refrigerant

• Tools Required: Refrigerant gauge set, refrigerant canister.
• Check the low-pressure service port for refrigerant pressure using the gauge.
• If the pressure is low, connect the refrigerant canister to the low-pressure port and follow the manufacturer’s instructions to recharge the system.
• Monitor the pressure until it reaches the manufacturer's specified level.

3. Inspect and Replace AC Compressor

• Tools Required: Socket set, wrench set, AC compressor replacement.
• Remove the serpentine belt by loosening the tensioner.
• Disconnect electrical connectors from the AC compressor.
• Remove refrigerant lines connected to the compressor (ensure proper recovery of refrigerant).
• Unbolt the old compressor and replace it with the new unit, ensuring proper alignment.
• Reconnect refrigerant lines and electrical connectors.

4. Replace Cabin Air Filter

• Tools Required: None (may vary by installation).
• Locate the cabin air filter access panel (usually behind the glove box).
• Open the access panel and remove the old cabin air filter.
• Install the new cabin air filter, ensuring it is oriented correctly.

5. Recheck System Functionality

• Reconnect the battery.
• Start the vehicle and turn on the AC system to the maximum setting.
• Check for any leaks around the AC compressor and lines.
• Ensure the AC is blowing cold air and operating normally.
