I replaced the headlight wiper arm that I snapped, and replaced the blades too and noticed one side (not the side I had to replace) is not working. Is the headlight wiper motor difficult to replace? I will have a look at it properly next week as it is a non-neccesary luxury. Any tips on motor replacement appreciated, as again nothing in Haynes manual about this. Do Eurocarparts or GSF sell the motor? Didn't see it when ordering other parts. Cheers.
