Condition

Cause
This condition may be caused by an open sheet metal seam in the metal support panel between the frame rail and the rocker panel.
Correction
1. Raise the vehicle on a hoist. Refer to Lifting and Jacking the Vehicle in the General Information Subsection of the Service Manual.
2. Locate the support panel between the underbody frame rail and the rocker panel. It is in the middle of the underbody of the vehicle just behind the front doors. The support panels on both sides of the vehicle must be sealed.
