Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check and Replace Cabin Air Filter

Locate the cabin air filter access panel, usually under the glove compartment.
Remove the panel by unscrewing any screws or unclipping it.
Take out the old cabin air filter and inspect for dirt or debris.
Insert a new cabin air filter, ensuring it is oriented correctly.
Reattach the access panel.

3. Inspect and Replace Blower Motor

Remove any interior panels obstructing access to the blower motor.
Disconnect the electrical connector from the blower motor.
Unbolt the blower motor from its housing using a socket set.
Remove the blower motor and inspect for damage or debris.
Install a new blower motor if necessary, secure it, and reconnect the electrical connector.

4. Recharge Refrigerant (if applicable)

Connect a refrigerant gauge to the low-pressure port of the AC system.
Check the refrigerant level and add refrigerant as needed, following manufacturer specifications.
Ensure the system is not overfilled and monitor for any leaks.

5. Reconnect Battery and Test System

Reconnect the negative battery terminal.
Start the vehicle and operate the climate control system at different settings.
Monitor for proper airflow, temperature output, and functionality of controls.
