Water Leak and Wind Noise Diagnosis and Repair
This section describes the procedures for diagnosing and repairing water leaks and wind noise in Jeep vehicles. It includes methods such as the spray test, ultrasonic test, and light test to identify the source of the leak.
The manual emphasizes the importance of complete and accurate diagnosis, as water leaks can be deceiving and may not be immediately apparent. It also provides guidance on how to perform the spray test, including starting from the bottom and simulating wind-driven water.
The ultrasonic test is also described, which uses high-frequency sound to detect leaks. The light test is another method for finding sealer skips in sheet metal joints and seams.
