Information
The water leaking into the fuse box is caused by possible
contact between the fuse box housing and a PVC seam on
the vehicle body.
This contact can cause the fuse box to become deformed
and result in a leak on the fuse box cover.
To prevent future water leaks, the fuse box cover must be
replaced, and the PVC seam between the fuse box and
unpainted bodyshell must be reworked.
