Solution

1. Preparation

Tools Required:
- Screwdriver set
- Hose clamp pliers
- Heat gun or blow dryer
- Vacuum cleaner (optional)
Ensure the engine is off and cool.
Disconnect the vehicle's battery to prevent any electrical issues.

2. Remove Air Intake Duct

Locate the air intake duct connected to the air filter and the throttle body.
Use a screwdriver to loosen the clamps securing the duct.
Carefully detach the duct from both the air filter and throttle body.

3. Clear Ice Buildup

Use a heat gun or blow dryer on a low setting to gently warm the area where ice has formed. Keep the heat source moving to avoid damaging any components.
If possible, use a vacuum cleaner to remove any loose ice fragments and debris.
Do not use sharp tools to scrape off the ice, as this can cause damage to the intake components.

4. Inspect and Clean Components

Check the air filter for any moisture; if wet, replace it with a new one.
Inspect the intake manifold and throttle body for any remaining ice or moisture, cleaning as necessary with a soft cloth.

5. Reassemble System

Reattach the air intake duct, ensuring it fits snugly against the air filter and throttle body.
Tighten all clamps securely to prevent any air leaks.
Reconnect the vehicle's battery.
