Windscreen wiper motor (Opel Vectra B)

The windscreen wiper control in the Vectra is influenced by a technical subtlety – a multi-timer (see pages 159 and 227). In intermittent mode, depending on the speed of movement, it provides a longer or shorter interval of movement of the windshield wipers. But in the basic connection diagram of the windshield wiper motor, nothing changes:

The windshield wiper motor receives current through the appropriate fuse. The wire terminals on the windshield wiper motor have the following meaning:

• 53 supplies voltage for operation of windshield wipers at first speed.
• 53V supplies voltage for the windshield wipers to operate at the second speed.
• 53A provides constant current to the wiper motor (responsible for the reverse movement of the windshield wipers).
• 53E after turning off the windscreen wipers makes them return to the parking position and ensures that the motor is locked in the final position.

Tip: When the ignition is on, the windshield wiper blades should not be blocked outside their parking position - for example, due to a thick layer of snow or freezing. In this case, voltage is constantly supplied from terminal 53A. Since the windshield wiper motor cannot work due to the frozen blades, it burns out after a while. In such cases, you need to lift the blades so that they can return to their original position.

Is the windshield wiper motor or power supply wire faulty?

The following check will help to identify a fault in the windshield wiper motor, its wire or switch:



Expose the windshield wiper motor as described in the section "Removing the windshield wiper motor".

Disconnect the multi-pin connector on the wiper motor.

Then two auxiliary wires are laid.

The second wire is laid from the negative terminal of the battery to terminal 31 on the windshield wiper motor (where the brown wire is).

The windscreen wiper motor should now operate depending on the terminal used, either on stage 1 or stage 2. If not, it is faulty.

If it works, then the defect is in the switch or in the wire.

Removal the windshield wiper motor

Remove the windshield wiper arms.

Unscrew the plastic nuts underneath.

Remove the rubber gasket from the water repellent.

Remove the water repellent from the side clips and remove.
