Rear windscreen washer doesn't work, continually blows fuse

[CPDS3]

Hi all,

A slight variation of the common "windscreen washers don't work" thread.

Neither worked, so I went and replaced the fuse. Front worked, back didn't. After trying the back one it blew the fuse again.

I tried this a couple more times and the rear blew the fuse every time...

Apart from only using my front washers and avoiding the rear all together, does anyone have any suggestions of what I can check/ fix?

If I remember correctly this is a fairly common problem, cured by using a higher-rated fuse. If you do a search on here you may find posts confirming that, or somebody else may know for sure.

The back wiper blowing isn't a common issue.

You could try up-rating the fuse but as this isn't a common fault I suspect something auxiliary may be at fault.

You just HAD to go there! -_-

As there is only one pump and therefore one fuse, I'd surmise the rear pipe is blocked somewhere (maybe at the screen) - perhaps due to lack of use?

Or you may need to purge the line going to the rear screen if there is no flow - the pump overheats pretty quickly with no water.

Perhaps putting in a 15amp fuse (as mentioned in similar threads) until the flow has returned (hoping that it's enough to clear the blockage) would be the simplest option.

If you get excited, item 22 in the attached picture is the t piece where the front and rear jets separate, but I'm not sure how easy it is to get to that item.

You could unplug it and see whether you have fluid to there, to determine if the blockage is downstream.
