Rubber Seal Inspection

WARNING: This page is about a different car, the 2003 Infiniti QX4. However, it is still accessible from the selected car via links, so may be relevant.

Most waterproof connectors are provided with a rubber seal between the male and female connectors. If the seal is missing, the waterproof performance may not meet specifications.
The rubber seal may come off when connectors are disconnected. Whenever connectors are reconnected, make sure the rubber seal is properly installed on either side of male or female connector.
