Solution

1. Cabin Air Filter Inspection

Locate the cabin air filter: Open the glove compartment and remove any contents.
Remove the glove compartment: Depress the sides to release it and let it hang down.
Access the filter: Remove the cover for the cabin air filter.
Inspect the filter: Check for dirt, debris, or mold; replace if necessary.
Reassemble: Reinstall the cover and glove compartment.

2. Check for Coolant Leaks

Visual inspection: Look for any signs of coolant leaking around the engine bay.
Check coolant level: Ensure that the coolant reservoir is at the appropriate level.
Repair leaks: If coolant is found leaking, replace the affected hoses or components.

3. Brake System Examination

Inspect brake pads: Remove the wheel to access the brake assembly.
Check for wear: Look for uneven wear on the brake pads; replace if necessary.
Inspect calipers: Ensure calipers are not sticking and causing overheating.
Reassemble: Replace the wheel and ensure lug nuts are torqued to specification.

4. HVAC System Cleaning

Access the HVAC system: Locate the air intake for the HVAC system.
Clean the vents: Use a vacuum or cleaning solution to remove any debris or mold.
Replace cabin air filter (if not done previously): Install a new filter if needed.
