Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked in a well-ventilated area.
Disconnect the battery if working on electrical components.

2. Replace Cabin Air Filter

Locate the cabin air filter compartment, typically behind the glove box.
Remove the glove box by unscrewing any fasteners and gently pulling it down.
Remove the old cabin air filter, noting its orientation.
Install the new cabin air filter, ensuring it is positioned correctly.
Reattach the glove box.

3. Inspect and Repair Seals

Examine door and window seals for cracks, tears, or signs of wear.
Clean the seals with a gentle cleaner to remove dirt and debris.
If any seals are damaged, replace them with OEM or equivalent parts.
Ensure all seals are seated properly to prevent water ingress.

4. Check and Service Air Conditioning System

Start the vehicle and turn on the A/C system to the coldest setting.
Use a thermometer to measure the temperature of the air from the vents.
If the air is not cold, check refrigerant levels using a refrigerant gauge.
If low, recharge the A/C system with the appropriate refrigerant.
Inspect for any leaks in the A/C system, including the compressor and hoses.

5. Inspect Heater Core

Look under the dashboard for any signs of coolant leaking from the heater core.
If a leak is detected, the heater core will need to be replaced:
- Drain the coolant from the system.
- Disconnect the heater hoses from the heater core.
- Remove the dashboard components necessary to access the heater core.
- Replace the heater core and reassemble the dashboard.
