Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shock.

Tools Required:

OBD-II scanner
Multimeter
Socket set
Torque wrench
Refrigerant pressure gauge

2. Replace Blown Fuse

Locate the fuse box and identify the correct fuse for the climate control system.
Remove the blown fuse and replace it with a new fuse of the same amperage.
Reconnect the battery and test the climate control system.

3. Inspect and Repair Connections

Remove the climate control module from the dashboard.
Inspect the wiring harness for any signs of wear, corrosion, or loose connections.
Clean any corrosion with electrical contact cleaner and secure connections tightly.
Reinstall the climate control module.

4. Test and Replace Blower Motor

Use a multimeter to check for voltage at the blower motor connector.
If there is no voltage, trace back and repair any wiring issues.
If the blower motor is faulty, remove it by:
- Disconnecting the electrical connector.
- Unscrewing the mounting bolts.
- Removing the blower motor from the housing.
Install the new blower motor and reconnect the electrical connector.

5. Check and Recharge A/C System

Connect the refrigerant pressure gauge to the service ports of the A/C system.
Check the refrigerant levels; if low, locate leaks and repair them.
Recharge the A/C system with the appropriate refrigerant per the manufacturer's specifications.
Test the system for proper operation.

6. Replace Cabin Air Filter

Locate the cabin air filter compartment, typically behind the glove box.
Remove the old cabin air filter.
Install the new cabin air filter, ensuring it is oriented correctly.
