Rear Windscreen Washer Is Blocked

[mr_infamy]

Hey guys

I've finally gotten around to addressing this problem on my car. The rear windscreen washer isn't squirting any water out, while the front ones are working fine. I've had a look on the forums and I've come to the conclusion that the hose is probably blocked.

What I'd like to know is, has anyone else had this problem? and if so, how did you go about fixing it? I assume I'm going to have to remove the head liner if possible.

Thanks in advance

Blowing some air from an air compressor through the line should unblock it, right?

well, you need to check if its a blockage or the pump is dead

so remove the pipe from the end of the line at the nozzle and hit the squirter, if it comes out, the nozzle is dirty. if it doesnt, there is either a blockage further up (check it by following the pipe) or the pump is dead. youll need to use your head with this one, but its quite simple!

yep, check the pump first - quick and easy

I suspect the check valve is blocked 'cos I've replaced the pump and that now works but still no rear squirt. Can you advise how to get to the check valve (see part 27461N on the attachment)?

Did you try what zei20l said? nozzle is the most likely thing to be blocked and easy to check by pulling the hose off the back of it.

Beyond that, looks like the hose runs along the inside of the sill where the wiring is. You'll need to pull up the kick panel (carefully, don't break irreplaceable clips!). Pull it apart at each connection you can to narrow down the blockage.
