upon seat height that is set.
CORRECTION

PROCEDURE
Move the driver’s seat to its highest position to obtain maximum clearance under the seat.
Check the harness under the driver’s seat near the end of the screw drive for up/down adjustment, to
observe if it is being chafed when the seat moves.
Repair or replace the harness as needed and secure it with an additional cable strap during installation.

removed).
