not squirting owt. No signs of leaks - front washer bottle has juice in - is there a rear bottle or d'ya reckon I'm blocked up?

There is only one washer bottle. Have you checked to see if the floor area around the CD changer is wet? It is common for the pipe to become disconnected in that area - probably as a result of the washer fluid freezing. See the thread below:

was that what it was, Sean?

I am having the same problem on mine. Have looked in boot but cannot see, feel any puddle of water under CD changer. Will try the old trick of sticking a needle down the jet to see if there is any blockage. failing that will try and work tube off to see if there is any flow from there. If not I am stumped and will have to investigate further. Has anyone else had same problem but not related to tube coming off???

I have this prob too - and i have water under/around the cd changer in the boot. I cant get the carpet up enough t o get under the cd changer (i assume this is where the pipe connection is?) - so do i have to remove the cd changer to get access to the plug? if so, how is it fixed? thanks!

I believe that the carpet (trim) in question is behind not under the CD changer.

The pipe connection is on the n/s/r wheel arch.
