Camry washer jets blocked - Part 3

The black gunk or Biofilm is still giving me problems. The proper fix is to remove the washer fluid reservoir and give it a thorough cleaning but...that involves jacking up and removing the drivers side wheel then removing the mudguard cover to gain access to remove the reservoir!

Decided to try a sort of cyclic flush-out to avoid the above.

In the last post related to this I mentioned that the passenger nozzle jets clogged up again - just when I thought I was done. Removed the nozzle from the bonnet as shown to check and yeah...clogged with black gunk again.

Disconnected the hose that feeds the nozzles and setup to try a primitive cyclic flush.

Pump out to empty the reservoir, refill about one third and pump out again...repeat.

Yellow is the first pump out, red the second.

Second pump out settling, bloody black stuff in there.

Third pump out...keep going.

Looking better...

Bugger...gunk from the black lagoon is back.

After another three pump outs (eight in total) we'll leave it at that...see what happens.
