SUBJECT: LUMBAR SEAT BLADDER NOT INFLATING OR DEFLATING

MODELS AFFECTED: 1988 SEVILLE TOURING SEDANS (STS)


Some 1988 Seville Touring Sedans (STS) may experience a condition where the hose leading from the lumbar bladder gets kinked and/or bent preventing the bag from inflating or deflating. This condition may be caused by an improperly routed hose from the lumbar bag. To repair this condition use the following procedure:

1. Remove seat and disconnect electrical connectors. Place seat on protected surface.
