Hi,
What a difference it makes to have a fully functional rear wash-wiper at last! (especially with the roads being so salty in this cold weather!)
I thought my rear wash-wipe pump had packed in; I didn't get so much as a trickle from the rear wash jets. Having taken the nozzle off (as described below) and activated the rear-wash, the jet of water cleared my 6ft garden fence!!! So.. my rear washer jets were 100% blocked!
1. Pull-off the plastic cowling that covers the washer jet. You need to spread the flaps that straddle each side of the wiper arm - the cowling should un-clip with a little persuasion.
2. Pull-off the washer jet nozzle - it's just a push fit (it may need wiggling as it'll have several years of crud holding it on!)

3. Take the nozzle inside and submerse it in vinegar in a small dish. Put the dish in the microwave for 10 seconds - NOT LONGER (the jets are metal - so do it at your own risk!) This is intended to speed-up the reaction between the acid (in the vinegar) and the calcium / oxide deposits in the jets.
Leave the nozzle to soak for 30 mins or so.
4. Get a twist-tie - importantly, you need the type that you'll find holding cables together when you buy an electronic appliance gadget etc, (the ones you get in sandwich bags are not rigid enough).

Strip a bit of sheath from the twist-tie to expose some bare wire. Gently prod, poke & twist the wire in each of the jets. If the crud won't shift, repeat step 3 and try prodding & poking again later! Providing your twist-tie wire isn't too big to fit in the jet, it will eventually work the crud loose.

Once you're able to "rod" the jets with the twist-tie, give both of them a vigorous roding and put them back in the vinegar for another 10 mins or so. For best results, suck or blow some vinegar through the jets (not very pleasant!)
Finish off by using a pin to rod the jets out even more. I covered the pin in some citrus gel (just like vinegar, the acid breaks down the crud) and wiped the crud off the pin each time it came out of the jet, until no more came out.

5. Use some tightly-screwed-up kitchen roll to de-gunge the main cavity of the nozzle, repeat until no more gunge comes out.
Do the same for the pipe that the nozzel clips-onto (on the car) and activate the rear-wash wiper to blast out any crud in the pipe. Try to do this as the postman walks past for extra points :D
6. Clip the nozzel back on and replace the plastic cowling!
