A different rear wash wipe problem

[GregorFuk]

My rear wash wipe has decided to stop working during this latest cold spell. Last time this happened the pipe had come apart in the passenger foot well but this time things are slightly different. If I push the stalk forward I can hear the motor working but the level inside the washer bottle doesn't seem to decrease. As a double check I've hunted inside the car and can't find any wet patches nor can I see any water dripping from underneath which seems to confirm that no water is being pumped.

Has anyone else had this problem or possible suggestion as to what could be up?

Cheers

Is it frozen?

No, I wouldn't have thought so. It was pretty mild on Saturday and it still wasn't flowing.

I went out this am and it was cold (-2C) and I tried the wash wipers (front and back) and nothing. I then tried holding the wash wiper for about 45 seconds and hey presto water started trickling and and then finally got full pressure from it on front. Then rear started working. It was probably frozen water in the lines or some other blockage and holding it for longer periods really helped. Try that!
