Can somebody help me understand where all this stuff is!! Washers not working so I'm looking to locate the relay which I believe is behind the panel on the passenger side – but which one is it? Also all the other items on the diagram below FW 7 through FW 14 of these all in one unit or separately housed in various units?

All help appreciated!

The big square FW5 is the "relay"(wiper control unit) and everything within the square(FW6 to 14) are integrated parts of it, it looks like a relay just a bit bigger, google out LR057366 to see how it looks maybe you find it then cos i dont know where it is on the early D1s like your's

Thank you so much! I guessed that square in the diagram must be all one unit, your confirmation saves me a lot of time. Difficult to test this fully, other than the relay itself, FW6, but I just looked at them online and they are between £10 and £12 so no big deal to change once I've checked out is getting power to it etc. Again, thank you
