The rear washer on my 2002 V70 has failed - no water. It co-incides with a family of mice moving into the rear. I suspect that the mice might have chewed through the plastic water pipe. Does anybody know: - does the V70 have a separate pump for the rear wash or does it use a single pump and a valve? - where along the run can I most easily access the water pipe - where is the pump/valve thanks DAvy
