Right. Before the memory fades. I am still in a state of gobsmackedness that this old guy with his failing eyesight has actually pulled it off.

Let's assume you already know that the RHD wiper motor for a 240 is a mirror image of the LHD unit, and the RHD unit is these days entirely unobtainable, except perhaps in Thailand. What to do?

First, go to Dai at Classic Swede and buy a LHD motor for £110.00 including shipping to France (where I live). Then get ready to cannibalise. Dai will tell you it's most likely the motor at fault, not the worm-drive transmission. In my case actually, the problem was one permanent magnet come unstuck from the wall of the motor casing. If I had known that in advance, I could have probably fixed it with Araldite. Or just swopped in the motor casing from the LHD unit and touched nothing else. But I was too far into wrecking the old motor before I saw the light. Went to bed last night assuming that this otherwise excellent 30 year old car was a goner – on account of the wiper motor! – and did not sleep well. At breakfast, gave myself a talking-to and went out to the shed to try again. Used old motor casing (no choice). New motor armature. Old plastic ring that mounts the brushes etc (again no choice). New driving axle with its new/different system of cams on the plastic worm-driven cog. And bless my soul, it works! The unit as a whole, old or new, is a piece of **** to work on, with not enough space inside for its wires. The mirror-imaging of LHD to RHD means the standard wires are stretched perilously tight. Someone more electrics-savvy than me would add length. I am presently waiting for a man who knows a bit more than me to come and reconnect the wiper armature, and hope that this will eliminate a certain clickety-click that I am presently hearing from the motor. And that, so far, is the story. Thank you for listening.

Cheers
