Everning all. I just got a 97 D1 300tdi recently (my second) and the intermittent wipers don't work. The two speeds work as does the single wipe. Any ideas? Not the end of the world but would like to get to bottom of it when I've gotten over all the other nigglies! :D All fuses good except the adjustable mirrors fuse. Replaced that. Worked for a bit then blew again. Cheers and good day.
 
The D1s multi function unit (MFU) looks after the windscreen wiper sweep delay, so that particular circuit may be iffy, the MFU also handles among other things the delay of the interior lighting, also it has a test function the procedure for that is in various LR forums workshop manua.

The10amp fuse no.18 protects circuits for the electric mirror adjustment, also protects tailgate wash/wipe and cruise control, so issues with these could blow that fuse.

Thanks buddy!
 
The MFU probably directly triggers the relay in the drivers footwell (RHD). My relay was faulty - replaced and intermittent came back.
Ah. Yes. Relay. I never thought of that. The older I get the more I seem to forget. I'm going to have a look this weekend. Been busy since the OP.
Cheers.

Yes it does, so good call as the power supply from the wiper switch to the wiper motor is direct for normal and fast speeds.
