My rear wiper stopped working (the washer never did work) which many owners will recognise as a fairly common problem. Having bought in a new (genuine) motor and a new arm + blade I tackled the job yesterday. Only suffered one finger cut prising the tailgate panel out of its locator clips. The replacement took only 40 minutes to complete and the wiper is restored and for the first time in my ownership there is a functioning washer to. The cost of the parts were £270 from a LR authorised dealer via eBay which is rather a lot of money for a rear wiper motor and arm whichever way you look at it.
Having completed the task I decided to call the local LR Dealership and ask for a price to supply and fit the rear wiper parts and they gave me a price of £528. that made me feel a lot better about spending £270, just earned myself £258 for 40 minutes work. Result!
