DS3 2011 rear window wipers/wash doesn't work

Post by sebbDS3 »

Since a couple of weeks ago my back window wipers has stopped working. Nothing happens when I put the car in reverse (it usually wipes when put in reverse) and nothing happens when I turn the wiper switch on. There's no sound coming from the pump and there no washer fluid coming from the nozzle then I turn the switch all the way.

For the windshield everything works fine, both wipers and wash so I don't think there's something wrong with the pump nor the electronics in the switch.

I have tried swapping out the 15A fuse F1 in the dashboard fuse box, with a new one, with no luck.

I have noticed there's another fuse in the engine compartment (F3, 10A) that is assigned to the front/rear screen wash. Though it seems strange to me since the windshield wipers works perfectly...

Could that fuse be the problem or is there something else I could try to make the back window wipers work again?

Edit: changed engine compartment fuse box to dashboard fuse box

It might help if you pop your VIN up then I can see the electrical system for your car. Fuse F1 on the engine fusebox is a multifunction motor control.

The fuse for the rear wiper is located in the passenger compartment under the BSI - bottom row of fuses F1 - not the Engine Fusebox under the bonnet.

My bad - I was too fast on the keys. I have swapped the F1 fuse in the dashboard fuse box, not the engine compartment fuse box, according to this diagram:

Ok, to be sure, if you have your VIN handy I'll look up the electrical circuit to double check the fuse as they can vary.

The rear wiper motor is controlled by a relay on the BSI, but I would look at the connection to the rear motor first of all:

5215 is the rear motor. Pin 3 is the earth
521: Rear windscreen wiper motor command (Pin 1)
522: rear wiper motor fixed stop control (Pin 2)

The earthing point (MC60) is on the rear tailgate located below:

So I would check the plug connections there first of all and the condition of the pins and socket for damage or water.
