I've eventually got around to installing/replacing the rear wash/wipe system on my 1995 Defender.
I've used a Carling switch as I couldn't find an OEM switch at a reasonable price. This is now wired in and passes power to the remains of the loom at the back door. Trouble is, the new motor won't go when the switch is "on". The second spring-loaded part of the switch operates the washer so something's OK there, but not a sign of any movement at the motor.
There are 5 connections to the motor. The 3 on the top are brown/lt green, green, and black and the 2 at the "back" are red/lt green, black. With the switch on I get power at the green (centre live feed) on the 3-pin connection, and power at the red/lt green pin of the 2-pin connector. 2 of the other wires on each connector are earths, which leaves one of the top wires (brown/lt green) apparently dead, so I assume this will carry power to operate the park switch when the motor is running.
As far as I can work out, then, the motor has all it needs to get moving....how can I test it? Which connections need live and earth just to get it to turn? I'm guessing the 2-pin is what makes it actually go, but 12v and earth to those pins has produced no response.
'elp!
