Solution

1. Preparation

Gather necessary tools: flashlight, thermal imaging camera, water spray bottle, and weather stripping adhesive.
Ensure the vehicle is parked on a flat surface and is turned off.

2. Inspect and Replace Door Seals

Sub-steps:
1. Open each door and visually inspect the rubber seals for cracks or gaps.
2. If damaged, gently pry off the old seal using a trim removal tool.
3. Clean the mounting surface with isopropyl alcohol.
4. Cut the new weather stripping to length and press it firmly into place.
5. Ensure it aligns correctly with the door frame.

3. Check Trunk and Hood Seals

Sub-steps:
1. Open the trunk and hood, inspecting the seals in the same manner as the door seals.
2. Replace any damaged seals using the same procedure as above.

4. Perform Air Leak Repair

Sub-steps:
1. If leaks are found using the pressure test, mark the areas.
2. Apply weather stripping adhesive around the affected areas, ensuring a tight seal.
3. Allow the adhesive to cure according to the manufacturer's instructions before re-testing.

5. Test HVAC System

Sub-steps:
1. Ensure the HVAC system is set to heat mode and check for proper air distribution.
2. If air is flowing incorrectly, inspect the HVAC controls and ducting for blockages or malfunctions.
