Hey, No water comes thru when i try to clean my windscreen, does this mean that my water pump is broken?, is it a serious problem, easy to fix?

*if* you can hear the pump then chances are the nozzles or the little plastic non-return valve are just blocked, could also check the end of the pipe inside the bottle, it could be clogged there.

I had 2 problems that needed fixing with mine. 1) the elect. connection at the pump needed cleaning and 2) the "non-return" valves were blocking flow in both directions. You can get by without them - just need to wait a little longer for the fluid to come up the line. -But of course that's better than not having to wait so long, and then getting nothing out of the squirters.

Check the hoses for kinks too - they seem to like to kink up where the hose bends when the hood is shut. My pump was buzzing good, but no fluid was coming because of the kink that only blocked the flow when the hood was shut.

I also bought an extra pump just for safe keeping.
