LS 400
Title:
1993 LS 400 INSTRUMENT PANEL
LS 400's have warning indicator lenses (located on the underside of the instrument cluster finish panel) which project images onto the meter glass. Some early production 1993 models may exhibit partial delamination of one or both of the lenses due to interference between the warning indicator lens and instrument cluster finish panel. This may cause a buckled appearance for the lens(es) or light leaks visible in low ambient light conditions.
PRODUCTION CHANGE
Clearance was increased between the indicator lamp lens and the instrument cluster finish panel.

c) Carefully align the new lens inner corners with the cluster finish panel opening as shown in the circle area.
d) Finish positioning the lens in the opening and apply strong finger pressure to secure the adhesive.
