Solution

1. Preparation

Gather necessary tools: socket set, multimeter, OBD-II scanner, refrigerant gauge, and replacement parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Locate the fuse box (usually under the dashboard on the driver's side).
Identify the climate control fuse using the diagram on the fuse box cover.
Remove the fuse and check for continuity with a multimeter.
Replace any blown fuses with the same amperage rating.

3. Repair or Replace Wiring Harness

Visually inspect the wiring harness connected to the climate control unit for frayed or damaged wires.
If damage is found, repair the affected wires using solder and heat shrink tubing or replace the entire harness if necessary.

4. Test and Replace Blower Motor

Disconnect the blower motor connector and apply direct power to test its operation.
If the blower motor does not run, remove it by unscrewing the mounting screws and disconnecting it from the housing.
Install a new blower motor by reversing the removal steps and ensure proper connections.

5. Recharge Refrigerant

Connect the refrigerant gauge to the low-pressure service port of the A/C system.
Check the refrigerant level; if low, follow the manufacturer's specifications to recharge the system with the correct type of refrigerant.
Monitor the system while recharging to ensure no leaks are present.

6. Replace Cabin Air Filter

Locate the cabin air filter housing, typically behind the glove compartment.
Remove the glove compartment for access.
Take out the old cabin air filter and replace it with a new one, ensuring proper orientation.
