what causes condensation to form inside my Ford F-150

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect and Replace Cabin Air Filter

• Tools Required: Screwdriver, replacement cabin air filter.
• Locate the cabin air filter housing (usually behind the glove compartment).
• Remove the screws or clips securing the housing and take out the old filter.
• Inspect the housing for moisture and clean it if necessary.
• Install the new cabin air filter and reassemble the housing.

3. Check Seals and Weatherstripping

• Tools Required: None.
• Visually inspect the weatherstripping around doors, windows, and the sunroof for cracks or missing areas.
• Replace any damaged seals using OEM parts to ensure proper fit and moisture prevention.

4. Clean and Clear Drainage Areas

• Tools Required: Compressed air or flexible wire.
• Locate and inspect the drainage tubes from the sunroof or cowl area for blockages.
• Use compressed air or a wire to clear any obstructions in the drainage system.
• Ensure that water flows freely through these drains.

5. Inspect HVAC System

• Tools Required: None.
• Turn on the HVAC system and check that the AC is working properly. Ensure that it is set to "fresh air" mode to allow for proper air circulation.
• If the AC is not functioning, service it as needed, which may include recharging refrigerant or replacing components.
