A minor and yet a strange issue the other day. The LC has IMO a very small windscreen washer bottle, and with 4 jets at the front and two at the rear it is not unusual to find it empty when you need it most. So I knew I was going on a long journey and had checked everything was OK tyres/fluids et al were all good. As I was driving at night the bugs get attracted to the headlights and it is not long before the windscreen resembles a killing field.
A couple of squirts and all was nice and clear, an hour or so and another clean needed......and there was no water hitting the screen? I could not have used up the container already, I checked the rear washer and it worked for a second then that too stopped. So next stop in the garage which typically in Spain could be another two hours away as 24/7 is still pretty rare when not on a motorway.
Eventually found a garage and checked the water and it was more or less full....hmmm

.
It could not be jets blocked because they all stopped at the same time, so I washed the screen with the hose and picked up a couple of bottles of water from the shop and finished the journey.
Yesterday I went to the garage to check it out, the pumps were running ok so it must be the filters in the pumps, bearing in mind the car had stood for over a year so I guessed they might be blocked with some kind of nasty growth. The bottle looked clean inside as I do not use additives just plain tap water, to get the pumps out you have to move the fuse box out of the way, out come the pumps and there are no filters, water flowed out and the bottle emptied. It turns out that the tubes leading to the jets were blocked, right from the jets (front and rear) back up the tubes around three inches, WTF!
All jets were working fine one minute and then seemingly in an hour the whole system became blocked! It was all calcium and took nearly three hours to clear the tubes and jets out, no sooner had I thought they were clear that a few seconds later they blocked again
Eventually the fronts and rears flowed OK, I went to the mall and picked up a gallon of screen wash, pumped some of that through just to make sure the system was clean. This might not seem to be a big deal and we all are familiar with one jet blocking and giving it a clean with a pin and all is well but to lose all SIX jets at the same time is IME very unusual, you work with cars for years and you think you are quite savvy around them, and then along comes something as odd as this to catch you out.
