My headlamp washers don't work, I'm hoping it's just a fuse LOL Anyone know if one of these is the one I should look at? (It's the fuse terminal at the drivers side dash)

Unlikely to be fuse as several functions operate off the same circuit.

But if you think it is a fuse, it won’t take more than a few minutes to check them all.

What is the nature of the faulty? can you hear the pump operating.
Do the windscreen squirters still operate?
Are the lights on or off?


I am assuming you have the car doors closed.
 
Yes, doors are shut, lights are on, and on pressing the button, zippo, nothing at all, which led me to believe there's no power getting to them, hence the first diagnosis would be the fuse. Before I check ALL those fuses, is that were the headlamp one resides or is there one under the bonnet?
 
I’m pretty sure the fuse for headlamp washer pump is in the engine bay fuse box. However if it has blown that will usually be for a worse cause, unless it’s happened in the winter if the washer fluid was frozen when it was last operated.

Good to know, will check that out in daylight and see if it's anything obvious...
