Dont think theres a
guide, but its an easy enough fix.
1. Make sure the actual water/mix in the bottle isnt frozen.
2. Make sure the nozel is clear, so thats not blocking the flow.
If both are ok, then get someone to spray the rear washer for 10 seconds or so and you have a look around.
1. Check behind the front n/s wheel, you might see water/mix dripping down which leads to the fault in the bay. Most likely the pipe underneath the airbox has blown apart. Remove the airbox, fit the 2 "ends" of the pipe together and tighten the jubilee clip.
2. Check the cloth trim on the o/s in the boot. If this is soggy then it will have popped off behind that. I think you need to remove the plastic at the top of the seatbelt to get into it. Should be easy enough from there.
3. Check the boot plastic, there could be water dripping from that. In this case the pipe has popped off where it joins the rear wiper/washer. Remove the bootlid plastic and attach the pipe accordingly.
