Begin the front seat adjuster motor replacement by taking out the seat. The next step requires removal of the six-way power seat adjuster. The first step involves removing wires from the front vertical gearnut motor together with the rear vertical gearnut motor and horizontal adjuster motor during disassembly. Depress the nut which connects the motor support bracket front to the inboard adjuster before extracting it partially from its positions with adjuster and gear-nut drives (3, 13). The completion of support bracket with motors attached requires disconnection of the front vertical drive cable and rear vertical drive cable and horizontal drive cable from the motors. As a first step remove the metal from grommet end(s) that secured motor to support then proceed to separate the motors. You should drill through the top end of the grommet with an 8 mm (3/16-inch) drill bit. Insert the grommet onto the motor support bracket prior to rivet a 3/16-inch fastener into the grommet to keep the motor securely attached. The drive cables must connect to motors after installation of the motor on the inboard adjuster with a securing nut and following the connection of motor feed wires. Reinstall both the front seat together with the six-way power seat adjuster.

The replacement procedure for the lumbar motor begins with removal of the adjuster followed by dismounting the front passenger seat. Disconnect the air supply hoses that connect to the lumbar module as well as the electric connectors. Pull the leather module pouch open and extract the module from its installation position. To install the lumbar module, first secure it within its leather pouch then reconnect electrical connectors and air supply hoses to the lumbar module. After installation complete both the front passenger seat and the adjuster.
