WATER LEAK DETECTION AND IDENTIFICATION
CONDITION: Interior Water Leaks
First, use the customer's statements to determine the following:
- Where is it wet? (Examples: near the wheel house, in the spare tire well, at the front, at the back)
- When does it leak? (Examples: while parked level, while parked on a slope, while driving, only during heavy down pours)
- What color is the moisture? (Examples: muddy water from the road surface, clean water from above)
- How wet? (Examples: light dampness after a heavy rain, soaking while driving in a drizzle)
Based on the customer's statements, some determinations can be made:
- Location of possible leak points near the damp area.
- Dirty water usually comes from below. Check the wheel house weld seams, floor plug, lower air vents, etc.
- Clean water usually comes from upper panel surfaces. Check the trunk lid seal, around the windows, sunroof drains, door panel moisture barriers, etc.
- Leaks noted only while the vehicle is parked are usually associated with water leaking in at one point and seeping to another. Also, damaged seals can leak like this but may not show visible damage.
