Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to prevent electrical issues.

2. Inspect and Clear AC Drain Tube

Locate the AC drain tube, usually found under the vehicle near the firewall.
Use compressed air to blow out any debris or blockages in the drain tube.
Check for proper drainage by running the AC and observing water flow outside the vehicle.

3. Replace Cabin Air Filter

Open the glove compartment and remove any contents.
Unclip the glove compartment to allow it to drop down.
Locate and remove the cabin air filter cover.
Replace the old cabin air filter with a new one, ensuring it is oriented correctly.

4. Inspect Evaporator Coil

Remove the dashboard cover to access the HVAC unit.
Check the evaporator coil for ice or frost buildup.
If frozen, allow the vehicle to idle with the AC turned off until it defrosts.
Inspect for any airflow obstructions.

5. Check Refrigerant Levels

Connect a manifold gauge set to the AC service ports.
Verify that the pressure readings are within manufacturer specifications.
If low, evacuate and recharge the AC system with the correct type and amount of refrigerant.

6. Reassemble Components

Reattach the dashboard cover and glove compartment.
Reconnect the battery.
Ensure all tools are removed from the vehicle.
