Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multi-meter, and screwdrivers.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check Coolant Levels

Open the hood and locate the coolant reservoir.
Ensure the coolant is at the recommended level. If low, top off with the manufacturer-recommended coolant.
Inspect for any leaks around hoses and connections.

3. Inspect Cabin Air Filter

Locate the cabin air filter, typically behind the glove compartment.
Remove the glove compartment to access the filter compartment.
Remove the filter and inspect for dirt or blockages. Replace if necessary.

4. Check Heating System Components

Use a multi-meter to check the continuity of the heating elements and fuses.
Remove any faulty components and replace them with new, OEM parts.
Ensure all electrical connections are secure.

5. Refill and Bleed Cooling System (if necessary)

If coolant was added, run the engine until it reaches operating temperature while monitoring for air pockets.
If air pockets are present, bleed the cooling system according to the manufacturer’s guidelines.
