| Condition | Customer may comment on finding water in the rear interior of the cab. |
| Cause | 5203798
5201854 5201855 Note: The cracks can be in the left and/or right side of the rear sliding window plastic upper rail glass guide which is covered by the roof rear spoiler. Examples of a left (1), then right side (2) visual crack (with the spoiler removed) are shown in the graphics above. The cause of the condition may be cracking in the rear sliding window plastic upper rail glass guide. The plastic upper rail glass guide may develop small fractures/cracking which allows water to pass through on the glass side of the urethane that attaches to the vehicle body. |
| Correction | Important: When verifying this condition, ensure that the water leak path is due to cracks in the rear sliding window plastic upper rail glass guide, and NOTa leak in the primary urethane seal, between the window and the body; or from the spoiler attachments to the truck cab which are in the same area. Please indicate power sliding rear window crack in warranty claim verbiage.
A leak in the primary urethane seal should be addressed by removing and resealing the window, using the standard service procedure from SI. R & R the roof rear spoiler and apply seam sealer to the rear sliding window top encapsulate, following the steps in the Service Procedure below. |
