Hello folks!

I'm a newbee with a problem, can someone please help me?

I have owned my Civic Type R for just over two years (trouble free!). But since I returned from my last holiday a couple of months ago my windscreen washers have been losing pressure intermittently. Sometimes they work and other times they just pump the water out with only enough pressure to reach the bottom of my windscreen. As my car sat garaged for a couple of weeks whilst I was away I was wondering if it could be some sort of an air lock? Hopefully it's not something more sinister!!!

Any help would be greatly appreciated.
