2000 CDX Auto: mystery of fuse no 6 function

[James Burton]

My windscreen washers, both front and rear have ceased to work - no sound from either pump motor.

In checking the fuse layout, I see that fuse no 6 in the drivers (RH) side fusebox, is the one to check.

However the descriptor states Fuse 6 : Front wipers and washers; Rear wipers and washers; Door lock control.

With exception of the washers, all other items are working normally. I have checked no blockage in the plastic tubing and no sediment in tank.

The lack of sound from the motor pumps indicates an electrical fault - but the fuse is good.

Any thoughts from this mix of owners and experts would be most welcome, as 'no washers' is a MOT fail. Yikes!

Many washers only have one pump - it's driven one way for front and the other for rear. So it may 'just' be the motor has died.

Thank you, I'd not thought of that - I'll see if I can reach underneath the tank to feel whether a 'two way pump' is the case, it would certainly explain all the symptoms.

disconnect the wiper plug from the pump, and check for 12v when the stalk is pulled/pushed to wash

2000 will be a Japan built yaris (JT VIN)

I would suspect the stalk is the issue (integrated relay)

2 wire, 2 outlet with check valves, the stalk swaps the polarity for front or rear
