why is my Honda Accord’s HVAC system blowing warm air

Solution

1. Preparation

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

2. Recharge the A/C System

• Tools Required: A/C refrigerant recharge kit, manifold gauge set
• Locate the low-pressure service port on the A/C system.
• Attach the low-pressure hose from the recharge kit to the service port.
• Start the engine and turn the A/C to maximum cooling.
• Slowly add refrigerant until the system reaches the recommended pressure (typically between 30-40 psi).
• Disconnect the recharge kit.

3. Replace the Cabin Air Filter

• Tools Required: Screwdriver (if applicable for access)
• Locate the cabin air filter access panel (usually behind the glove compartment).
• Remove the access panel and take out the old cabin air filter.
• Install the new cabin air filter, ensuring it is oriented correctly.
• Reassemble the access panel.

4. Inspect and Replace A/C Compressor (if necessary)

• Tools Required: Socket set, torque wrench, refrigerant recovery machine (if needed)
• Disconnect the electrical connector from the A/C compressor.
• Remove the drive belt from the compressor pulley.
• Unbolt the compressor from the engine and remove the refrigerant lines (recover refrigerant using the recovery machine if applicable).
• Install the new compressor, ensuring proper alignment and torque specifications for bolts (typically around 20-30 ft-lbs).
• Reconnect refrigerant lines and electrical connectors.
