So, first issue to be dealt with....wipers. 1988 90, 200Tdi conversion.
Previous owner reported that starting a couple of weeks ago, when activating the wipers, the fuse would blow!
Having done a bit a research, it would appear this is a common issue!
Some report it is the parking switch at fault, a stalled/stuck motor or damaged wiring.
Last night while I had her in the workshop at work taking a look, I unplugged the motor, isolated the vehicle battery and to check for a short to earth, I metered from the green wire to the black wire on the plug while the plug was disconnected and there was continuity! Is this correct.
Looking at the wiring diagrams I have found, it would seem that there is a fused supply to the steering column switch pack, this then splices off to the wiper motor and also to the reverse light switch.
A selection of other wires go to the wiper motor which I assume are, fast, slow, and intermittent....
So could I ask if anyone can confirm if this continuity between Green and Black on the wiper motor plug when unplugged and battery off is correct...and also how the system works....i.e. Power to motor on Green, Earth on Black....but I am not sure how the switch side of things works to get the motor to run!
Any clues would be a great help!
