Hi, My problem was that the drivers side wiper was not covering the whole section of the screen, the last 2 inches were not being covered. Thanks to these excellent instructions from Tim, I got the wipers working in a couple of hours(bit of a novice mechanic, 20 minutes was spend trying to find the 16mm nut from a cavity behind the front headlamps). The instructions make more sense once you start doing the job. Thanks again Tim..
