2892552 - E3051 ELECTRIC REAR WINDOWS - Functional description (SX setup)

Functional description

The electric windows relay J65 controls the operation of the front electric windows circuit. The electric windows relay is supplied by the direct line from the battery through the maxifuse J/B2 for B5 . The coil for the relay is supplied when the ignition is switched on (INT) from the line for fuse F8 for the junction unit B1 and is always earthed: the relay is therefore always energized when the ignition is switched on (INT). In this way, the line protected by fuse B17 supplies switches H47 (left), H48 (right) and H55 (rear electric windows lock) whose supply is controlled by the ignition (INT/A) and are connected to earth; in this way they are also lit up when the ignition is switched ON. When these switches are operated - if switch H55 is in the go ahead position - they send the control signals (positive and negative) to the switches in the rear doors H53 and H54 and from there to the motors N65 (left) and N66 (right): reversing the signals according to the contact which has been closed, determines the direction of rotation of the actual motor.
