DESCRIPTION OF OPERATION
The passenger seat can be adjusted using the switch on the outside of the seat. Electric motors move the seat lengthwise, change the height of the seat cushion at the front and rear and change the angle of the backrest.

When the ignition switch is in the Drive position, current is supplied via fuse 26 to switch 358 in the passenger seat.

The following electric motors can be controlled from switch 358 in the left-hand seat:
^ Electric motor 358A moves the seat forwards and rearwards.
^ Electric motor 358B raises or lowers the front of the seat.
^ Electric motor 358C raises or lowers the rear of the seat.
^ Electric motor 358D changes the angle of the seat backrest. The seat backrest can be reclined until it rests against the rear seat cushion. Forward movement is limited by microswitch 369.

Relay 446, which is controlled by the door switches, makes it possible to adjust the seat even when the ignition switch is in the OFF position.

FAULT DIAGNOSIS HINTS
The seat can be electrically adjusted with the ignition switch in the OFF position.
1. Check that fuse 26 is intact and that the fuses are supplied with current.
2. Check that current is supplied to switch 358.
3. Check that current is supplied to the motors by activating the corresponding switches.
4. Check the connectors, wiring harness and ground connections.
