how to troubleshoot the AC not blowing cold air in my Honda CR-V Sixth Generation (2023-present)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and turn off the ignition.
• Disconnect the battery to prevent any electrical shorts.

2. Leak Inspection

• Inspect all AC lines, components, and the evaporator core for refrigerant leaks.
• Use UV dye and a black light if necessary to identify any leaks.
• If leaks are found, proceed to repair or replace the affected components.

3. Recharge the AC System

• Connect the manifold gauge set to the service ports on the AC system.
• If refrigerant levels are low, use a refrigerant canister to recharge the system.
  • Open the low-pressure valve on the manifold gauge set.
  • Monitor the pressure and ensure it falls within manufacturer specifications (typically around 30-40 psi for low side).
• Ensure not to overcharge the system.

4. Replace Cabin Air Filter

• Locate the cabin air filter compartment, typically behind the glove box.
• Remove the glove box for access (if required).
• Remove the old cabin air filter and install a new one, ensuring proper orientation.

5. Test AC System

• Reconnect the battery and start the engine.
• Turn on the AC system to the maximum setting and check for cold air.
• Observe the AC compressor to ensure it engages properly.
