Hi all always meant to ask as I have recently sorted my rear wiper I have cleared the two holes but it just dribbles out no spray is that right? It’s a bit  Current stable:

My jets were blocked hence no water. Took the panel off inside the tailgate and pulled the pipe from the motor to the jets. Used some gentle compressed air reconnected the pipe and I just got a few blobs of water out. Did the same procedure another 3 times and I ended up with a nice wide spray.

Take the cap off and clean the jets out

I’ve poked a needle all the way through will that not work? How do you get the cap off? Current stable:

I think you have to take the spoiler off that's why I just did mine with air.

UPDTED WITH PHOTOS...

You do have to remove the spoiler - I did mine this evening and literally took 5 minutes.

First you have to remove the trim panel from the inside. Grab the top of the panel and pull away from the glass and then downwards. It can be quite stiff to start with if it’s not been off before - be bold...!



You should then see 3 silver bolt heads at the top (circled in red) - although the bottom edge now you have the tailgate up - these secure the spoiler to the car. (10mm)



Undo and remove them. Now, assuming you are standing behind the car, pull the spoiler towards you (pulling it towards the back of the car) as there are two white locating rings on the tailgate.



Once you have pulled the spoiler about 2 inches or so backwards it just ilfts up and off - Its attached by a cable which I guess i the high level stop light - I placed a couple of cloths on the roof and laid it back down as the wire is long enough to allow this without removing it.



Now you can get to the black plastic wiper arm cover - be a little careful as the plastic is likely to be a bit brittle. (ask me how I know)..! But I doubt they are expensive to replace.

Pull the larger end away from the window and when it starts to move, start to lever it towards the left as the rest of the cover sits under the wiper arm.

Once out, you will see the 2 tiny holes/jets - I used my air compressor to blow through but a very small pin will probably do the trick.

Fit in reverse - it litterally can be done in under 15 minutes

I will update this post with pics once my replacement plastic cap arrives as it all needs to come off for me to refit - The jets still work, i just snapped the corner off while using a screw driver to lever it first time
