my rear washer nozzle recently stopped working. The pump still works, and the nozzle is clear as I've tested both. I'm certain there is a clog in the line, but I've also heard there may be a check valve in the line that gets clogged over time...I can't find it lol.

I've taken out the tube directly behind the nozzle and unplugged the L shaped tube connector, then tried the washer switch. I could hear the motor going but nothing is coming out. I remember a few weeks ago it would still drip liquid but after a few cold nights it just stopped altogether... I wonder if its just a blocked tube or f anything is split because of the icy nights...

So I took the tank out and undid the tube for the rear washer, tried to unblock it by pumping through it with a tyre pump, that didn't do much. I could hear a slight hiss at the tail washer nozzle so I reconnected everything back and tried again, but only dripping. So I undid the L shape connector at the tail, and checked again, it's dripping still so not the problem with the nozzle... and next I did something that might be stupid... I pumped from the tail end, and heard a pop somewhere in the car, and now it won't even drip... so I must have blown something up... crap...

The hose is still attached to the tank, I guess if the pressure was too high it would have detached itself maybe, so there is something else in the car that popped...?

Am I right in thinking that I can take off the interior panels on the left side (closer to the washer tank) and check the hose or is it hidden somewhere else? I believe even if I took the cargo area trim off the hose will disappear into the body anyhow... any ideas gurus please?

 

I've checked the rear all the way from where the hose drops down from the tail gate hinge to the tail light to where the hose goes from the front footwell to the engine bay. I'm sure something must have popped cos' the washer tank is now almost empty (up to the level of the hose to the rear washer) so it must have been leaking from the broken connection. However I did not find any wetness in the side under the door trims, under the boot area / tail light however I did feel some moisture at the hole where the tube goes into the engine bay. I didn't notice any water marks under the car either so I'm a little puzzled where it had all gone...

Unfortunately I can't quite see where the hose goes in the engine bay... I'm just curious what other connections that could have popped... other than the L just by the rear washer nozzle and the bottle...
