Solution

1. Preparation

Park the vehicle on a flat surface and turn off the ignition.
Disconnect the negative terminal of the battery to ensure safety.
Gather necessary tools and replacement parts.

2. Inspect and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Use a fuse puller to remove the climate control-related fuses.
Inspect each fuse for continuity using a multimeter. Replace any blown fuses with the same amp rating.

3. Replace Cabin Air Filter

Access the cabin air filter compartment, usually located behind the glove box.
Remove the glove box by unscrewing it and unclipping any retaining tabs.
Take out the old cabin air filter and clean the housing.
Install a new cabin air filter, ensuring it is oriented correctly.

4. Test and Replace Blower Motor

Locate the blower motor, usually beneath the dashboard on the passenger side.
Disconnect the electrical connector and use a multimeter to test for voltage.
If no voltage is present, check the wiring and connections; repair as necessary.
If the blower motor is faulty, remove it by unscrewing any mounting screws and replace it with a new unit.

5. Recharge AC System

Connect a refrigerant gauge to the AC service ports.
Check the refrigerant level and inspect for leaks using a UV light.
If low, recharge the system with the appropriate refrigerant per manufacturer specifications.
