why does my Honda Accord's AC blow warm air when on Max AC

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 systems.

2. Recharge the Refrigerant

• Tools Required: Refrigerant kit, manifold gauge set.
• Locate the low-pressure service port on the AC system.
• Attach the refrigerant gauge to the port.
• Add refrigerant to the system until it reaches the recommended pressure (typically between 30-40 PSI for R-134a).

3. Inspect and Replace AC Compressor (if necessary)

• Tools Required: Socket set, torque wrench.
• Remove any components obstructing access to the AC compressor.
• Disconnect the electrical connector and the refrigerant lines from the compressor.
• Unbolt the compressor from its mounting bracket and remove it.
• Install the new compressor, ensuring proper alignment and torque specifications.
• Reconnect the refrigerant lines and electrical connector.

4. Check and Replace Cabin Air Filter

• Tools Required: None (may vary).
• Locate the cabin air filter compartment (usually behind the glove box).
• Remove the old filter and inspect for dirt and debris.
• Install a new cabin air filter, ensuring it is oriented correctly.

5. Reconnect Battery and Test AC System

• Reconnect the battery terminals.
• Start the vehicle and set the AC to Max mode.
• Monitor the air temperature from the vents to ensure it is now blowing cold air.
