When Saint Serek replaced my wishbones, etc, the other week, as part of his attention to detail he checked my screenwashers - no wetness!
Ugh, I thought, I've not long cleaned the filter and cleaned the reservoir, so it should work.
Hearing this, Serek opened the feed connector halfway along the body edge, nearside, and blew down the tube section which led to the reservoir/pump.
Water issued forth from the reservoir filler cap, an d normal operation was restored.
I have two motives for sharing this: firstly, I may not be the only one who didn't know this trick and secondly, it has stopped washing the screen again.
I tried to repeat what Serek did, but after trying several different ploys, I simply could not separate that join.
How did Serek do it?
