U all sound so cute.. :) yes, our rear windscreen has washer..
Mayb BlackieLatio can try poking the nozzle outlet with a pin/needle, to check mayb it is block. Hold on longer to the washer and see if it helps.. :)
I poke the hole liao but there is still no water. I open up the bonnet & disconnect the tube that link up to the washer. With that disconnection i hold on to the washer, water split out the the hose.
Maybe really due to the connector problem. So far my 1 wk old car got few outstanding issues need to go bk TCM kp them liao.

a) Washer not working
b) Spoiler left hand side paint not spray
c) car boot closing got kong sound. Sound like metal knocking against each other
d) rear glass uv film got bubbles.
With these open issues i think must spent at least 1 full day there.
