I hadn’t driven the van for about eight weeks until yesterday whereupon I noticed my wipers weren’t working.
The van is under warranty so I will book it in somewhere to get it looked at but ….
I have obsessive need to know how stuff works so my preferred option would be to find and fix the problem myself.
So far I have checked the dashboard fuse number 43. This is fine, if I pull it the washers stop working so I know it fuse is OK.
I have downloaded an electrical circuits diagram for the Ducato which explains and locates all the of wiring connectors, along with the various fuseboxes and electronic modules.
Looking at the under-bonnet fuseboard the wiper 30Amp fuse is no. T20 along with a relay No. T19.
If I pull the electrical connector at the wiper motor and check the voyage across the pins I am getting readings around 9V. ignition off - 0 Volts. So something is getting there.
I have manually moved the wiper arms in case the motor had seized but all seems free enough. Obvs I gave the motor a light tap with hammer in an oldschool mechanic approach.
I will try the under-bonnet wiper fuse T20 next but my question is … if the relay, no. T19, has failed are they a specific Fiat part or a generic relay?
The relay is listed a 30Amp Micro on the electric diagram.
If they are a generic part should I be carrying a spare relay in my general toolkit?
