Tailgate wiper has stopped in furthest position from parked. Stripped trim out to have a look. The pipe to the washer jet was not fitted correctly, so there has been a small leak, but don't think this had anything to do with wiper problem. Cable to wiper has 3 wires. Haynes manual shows pin 1 through motor to pin 3 to earth (or other way round). Meter showed 12V pin 1 to pin 3 for few seconds after switch operated. I thought it might be high impedance through relay, so stuck 2 ohm resistor between these pins. Still driving good volts, so relay OK.
From earlier related post on this forum, Rustscrat mentioned wiper returns a signal to the BSI. Rustscrat can you explain please how the wiper is controlled? i.e. how does it sense full wipe and then perform reverse wipe? At least the wiper motor is easy to get at.
