General Description

The electric mechanism that operates the rear windows is of the conventional type (button pressed - in one direction or the other - the window closes or opens): the control switch is located on the centre console and may also be operated from the front seats.

For safety reasons a special consensus switch, also on the centre console, makes it possible to cut off the supply to the switches.

Operation of the rear power windows is only possible with the ignition switch engaged.

Functional Description

The rear power window relay I13 supplies and controls the entire system.

The relay coil is energised by a "key-operated" signal, leading from the ignition switch supply relay I35 and from fuse F4 of fusebox G1 (box "A") or from fuse F3 of box G1 (box "C");

this supply crosses the safety switch for consensus for the rear power windows B25: if pressed, this switch de- energises the coil of I13, completely cutting off the supply to the circuit, and contemporaneously turning on a led which lights up the ideogram [symbol].

Once the coil of relay I13 is energised, switches B23 and B24 are supplied with battery voltage which leads through the rear power window fuse F21 of fusebox G1 (box "A") or through fuse F23 of G1 (box "C").

The double switches supply the motors P16 and P17, sending a supply and an earth, inverting the signals depending on the contact that has been closed, thereby establishing the direction of rotation of the motor.
