I can hear the motor trying to "skoosh" the water through to my rear windscreen, but nothing is coming out. Can i get in to fix it myself somehow??

Thanks!!

It sounds like you might have a hole in the line somewhere. An easy trick before you try to take apart your car and find it is to take a needle and try to clean out the sprayer. In some vehicles that sprayer can get clogged and won't let the water spray out. You will hear your punp run but nothing will come out, and the pressure will build up and sometimes cause holes in the line.

Yes. You probably have a piece of gravel or dirt in the hole the water comes out. Use a needle or pin and poke the hole. It will remove the obstacle.

nobody knows

Its not a major problem,so don't worry.I think there must be a hole in the line,its better to check it with a needle and try to clean it.
