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 terminal of the battery for safety.

2. Replace Blown Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Use a fuse puller or pliers to remove the fuse related to the climate control.
Inspect the fuse; if it is blown, replace it with a new fuse of the same amperage.

3. Repair or Replace Climate Control Module

Remove any trim or panels blocking access to the climate control module.
Disconnect the wiring harness from the module.
Remove the mounting screws securing the module.
Install the new or repaired module by reversing the removal steps and reconnecting the wiring.

4. Inspect and Replace Blower Motor

Locate the blower motor, usually found under the glove compartment.
Disconnect the electrical connector from the blower motor.
Remove the mounting screws and take out the blower motor.
Install a new blower motor by reversing the removal steps, ensuring proper alignment.

5. Recharge AC System

Connect a manifold gauge set to the AC service ports.
Check the pressure readings; if low, evacuate the system using a vacuum pump.
Recharge the system with the manufacturer-recommended refrigerant type and quantity.

6. Replace Cabin Air Filter

Locate the cabin air filter access panel, often behind the glove box.
Remove the panel and take out the old filter.
Insert the new cabin air filter, ensuring it is oriented correctly, and replace the access panel.
