Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety during repairs.

2. Inspect and Replace Cabin Air Filter

Locate the cabin air filter compartment (usually behind the glove box).
Remove the glove box if necessary to access the filter.
Take out the old cabin air filter and inspect for dirt or blockages.
Install a new cabin air filter, ensuring it is oriented correctly.

3. Check and Replace Blower Motor Fuse

Locate the fuse box (refer to the owner's manual for exact location).
Identify the fuse for the blower motor and remove it.
Inspect the fuse for continuity using a multimeter.
Replace with a new fuse of the same amperage if blown.

4. Test the Blower Motor

Reconnect the battery.
Set the AC to the highest setting to check if the blower motor operates.
If no airflow, remove the blower motor from its housing.
Test the motor by connecting it directly to a power source; if it does not run, replace the blower motor.

5. Check and Service AC Compressor

Inspect the AC compressor for visible damage or leaks.
If the compressor does not engage, check the AC relay and replace if necessary.
If the compressor is faulty, evacuate the refrigerant, remove the old compressor, and install a new one.
