Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Inspect and Replace Fuses

Locate the fuse box, usually under the dashboard or in the engine compartment.
Use a fuse puller to remove the climate control fuse.
Inspect the fuse for any signs of damage or burn.
Replace with a fuse of the same amperage if necessary.

3. Replace Cabin Air Filter

Open the glove compartment and remove any contents.
Disconnect the glove compartment stop arm to allow it to drop fully.
Locate the cabin air filter cover and unclip it.
Remove the old cabin air filter and replace it with a new one, ensuring it is properly seated.

4. Test and Replace Blower Motor

Locate the blower motor, generally found beneath the dashboard on the passenger side.
Disconnect the wiring harness and remove the blower motor retaining screws.
Remove the blower motor from its housing.
Test the motor by applying direct power from a battery; if it does not operate, replace it with a new blower motor.

5. Recharge Refrigerant

Attach a refrigerant gauge to the low-pressure service port of the AC system.
Check the refrigerant level and, if low, add the appropriate refrigerant type according to the manufacturer's specifications.
Monitor the system for proper operation after recharging.

6. Reassemble and Test

Reconnect all disconnected components, ensuring all connectors are secured.
Reconnect the battery and start the engine.
Test the climate control system for proper functionality across all settings.
