I have a C-reg 1985 M6 with headlight wipers and washers.
The Manual says that K10 controls the wash/wipe - which it does for the windscreen, but not the headlight wipers.
I have two problems.
1) the washer pump for the headlights is on continuously (I had to disconnect it)
2) only one pair (pass side) of the headlight wipers move. The drivers side doesn't.
I'd like to check the Relay before rewiring it all, but can't find which one it is. (It isn't K10)
If anyone knows, or has a wiring diagram. It would really help.
