Solution

1. Preparation

Tools Required: OBD-II scanner, flashlight, rags, multimeter, safety goggles, gloves.
Safety Warnings: Disconnect the battery before working on electrical systems to prevent shocks or short circuits.

2. Inspect for Fluid Leaks

Raise the vehicle using jack stands.
Use a flashlight to look for any fluid leaks, particularly around the coolant reservoir and oil pan.
If found, identify the source and proceed to repair or replace the leaking component.

3. Replace Cabin Air Filter

Locate the cabin air filter housing, usually found behind the glove compartment.
Remove the glove compartment to access the filter.
Take out the old filter and replace it with a new one, ensuring it is oriented correctly.

4. Repair or Replace Damaged Wiring

Visually inspect wiring harnesses in the engine compartment for any signs of wear or damage.
Use a multimeter to test for continuity in damaged wires.
Repair any damaged wiring using electrical tape or replace sections as necessary.

5. Check Battery Cooling System
