    I suspect this is a silly question but bare with me. Basically i ran out of wiper fluid, refilled the wiper fluid tank, but now no fluid comes out the rare wiper. Does the rare wiper have a different tank or something, or is mine broken? I have looked at the jet holes but they seem fine. Any help would be appreciated.

    I had a rubber seal inside the motor fail and it caused washer fluid to pour down the inside of the boot into the spare tyre well. You could try unclipping the jet nozzle from the window wiper motor shaft and blowing it out with an airline!

    The pipe work leading to the washer had become disconnected. Take the boot trim and check the one connected to the motor first, if it's not that one is behind the sub enclosure.

    Mine initially was the pipe became disconnected then when popped back on worked fine. Next winter came and it stopped the jets themselves got blocked up all the way down to the motor needed a new one. But never changed it.

    Mine was just bits of crud blocking the nozzles (there are two)! Try clearing them with a pin before taking anything apart.

    Mine same as above jet washed the nozzle at the cleaners might be worth a go before you remove anything.

    Easiest way to test this for anyone with the same issue...

    just remove the rear nozzle completely and then see if the water shoots out in a straight line.. If it does, blocked nozzle..

    If it doesnt then check the pipe hasnt came loose by removing the rear bootlid trim... Just watch you dont cover your bootlid lock in fluid though or you'll have endless fun with your alarm... :)

    Just to add... If the nozzles are blocked & you keep testing without success, the pump pressure can actually blow the pipe off a connector! Which should be your second check. :)

    You can also remove the jet by pulling the plastic jet part out, try the pump to see if there is anything coming out without the back pressure that would be created by the jet nozzle.
    I had a blocked jet that a pin had no effect on so I got the smallest drill bit I had and drilled gently to remove the crud that had collected and blocked it from inside.
    Works perfectly now

    I attempted a fix on my wiper motor a few weeks ago. I was getting no water out either, and when I remove the arm bolt cover and then the small jet water did come out, put the jet back on and it appeared to work ok, but water was pouringout of the motor itself inside the boot. This was the seal that rikia93 mentioned. It is a daft design and basically a rubber washer prevents water filling the motor itself with water (as the water is fed through the centre of the motor).

    If the seal goes the motor usually becomes full of rusty water mixed with grease. I cleaned the whole lot up and didn't have a small o-ring to packout the rubber seal so used a ring of sealant on the rubber seal, packed the gears with greased and bolted it back up. Hopefully should be ok.
