The previous owner never took the car out in the rain. When I got it the wiper switch was frozen in the 'Off' position and the vacuum-powered original washer system disconnected.
I have freed up the wiper switch but have not actually tried the switch with power on to see if the wipers work because I am currently focused on the washer system. The original vacuum-powered system is ingenious and elegant but I am opting to leave the vacuum disconnected and have installed an electric pump using the original reservoir. This is partly because the switch doesn't push itself out again after being pushed to operate the washers and partly because I just don't want to risk vacuum leaks..
So, a few questions. I have looked in the spares books online and it seems the wiper motor is probably a Lucas DR3. Is that right? I gather that it needs to be paired with an appropriate Lucas switch for the park feature to work. It appears to be something to do with how the switch is wired internally. I'd like to install a switch to replace the original wiper/washer switch with the same look and functions - i.e. rotary, two wiper speeds and push for washer except the washer push needs to be electrical. Has anybody else done this and can advise me on a suitable switch. Looking around the internet it seems that Land Rover Series IIA and III may be a suitable source like this one:
