Washer jets mystery
 

I have a tourer with erratic washer jets. The rear is fine and has a strong jet but the bonnet washers are typically feeble though occasionally flip to full power. I’m assuming a blockage somewhere but where’s the best place to track it down?

The filter at the bottom of the bottle:cool: Just remove it and give it a good clean;)

Surely that would affect the rear jet equally. The rear is strong whilst fronts are weak. Don’t want to get the tank out if it’s something simpler

No need to remove the tank, just the front wheel. Peel back the liner and pull off the filter. Or, take the nozzles off and give them a good clean.
Alternatively, fit Ford Focus washer jets, much better:cool:

water jet mystery
 

hi andy, had similar problems with my saloon, turned out to be the T piece between the jets under the bonnet. poss non return valve issue or just drawing in air. john ,

If you detach the supply tubing to the under-bonnet T-piece, you can test everything from there back. Get an assistant to operate the washers while you watch the tube. If you get a faceful of screenwash, the problem is from the T-piece forwards. Maybe the washer jets are bunged up?

Thanks for the tips everyone. Investigations confirm a problem with the t-piece. I will now try and fix it, but if unsuccessful can anyone recommend a replacement part? I will also need new underbonnet insulation fixings. Damn those clumsy fingers!

You could possibly get new connectors and hose from a pet shop? I used stuff for fish tanks when sorting the rear screen wash on my ZR years ago, seems better suited tbh as more flexible and when I sold the car the new hose and connectors had been on the car longer than the oe stuff had managed to last.

I had (and still have to an extent) the same problem, I fixed it briefly by removing the supply pipe to the t piece and working the washers, the stuff that came out smelt foul.

When I filled the bottle with very hot water it bubbled up like a swamp, worked ok for a while though.

I'm thinking it's poor quality screenwash breaking down into jelly, my fix is going to be to drain it again, leave a bottle of white vinegar soaking in there for half a day or so, flush with boiling water then refill with quality screenwash.

Eventually found time to disassemble the t-piece and have a look. No dirt or jelly-like substances so reassembled and tested and working fine now. My theory is the return valve was sticking and is now freed up. With MOT tomorrow I have fingers crossed it stays that way. Thanks everyone for the helpful comments.
