Why aren't my 2023 Mitsubishi Triton's windscreen washers working?

Asked by Angus

My 2023 Mitsubishi Triton’s windscreen washers are not operating, but the wipers are – in all modes.

Let’s go back to basics here: Is there water in the reservoir? It might sound like a silly question, but many owners don’t think about routine maintenance like this, mainly because modern cars are so reliable in the first place.

If there is water in the reservoir, can you hear the washer pump motor when you hit the lever for the washers? If you can, then there could be a blockage in the line somewhere (it wouldn’t be the first time an insect or dust has blocked one of these tiny tubes). If you can’t hear the motor, the problem is most likely an electrical one and could be anything from a fried pump motor to a simple blown fuse.

Don’t be confused by the wipers working and the washers not; they’re two very separate systems.
