DESCRIPTION - HEADLAMP WASHER - Fiat GRANDE PUNTO 1.3 Multijet
The headlamp washer cleans the headlamp lenses as the windscreen is being cleaned.The headlamp washer function is managed by the Body Computer which automatically activates the headlamp washer, with the dipped headlamps on, when the windscreen washers are activated through the lever on the right of the steering wheel.The headlamp washer consists of a pump that sends detergent to two nozzles located in the bumpers which spray a powerful jet onto the headlamps.A timer activates the headlamp washer pump by means of a series of pulses lasting about half a second.The headlamp washer circuit is protected by a fuse and governed by a special relay located in the engine compartment junction unit.
