Drizzle fault

Greetings dear Lard Rover people!

I own a 2005 Land Rover Freelander 1 with the 2.0L diesel engine. The car has developed a tricky issue with the drizzle setting. When in drizzle mode, the wiper arms immediately get stuck once left the resting position. They wont move anywhere unless I turn on a wiper setting that isn't drizzle. Also the manual wipe action allows them to move, BUT only for the duration that the action is held. If I release it, wipers get instantly stuck where they were at the moment. Because of this, it's also not possible to just "tap" the manual wiping action so the wipers would do a full back and forth swing.

I thought the problem was with the wiper motor or the mechanism, but the motor has been replaced and the mechanism is just fine and the problem still persists. Car service man suggested a bit unsurely that the fault might lie in the "Multifunction module" and he suggested replacing this. Would you guys concur with this diagnosis? The matter has been dragging many months now because of the unsure diagnosis and the fact that I wasn't able to find these modules new from any of the Land Rover spare stores online.

I'm not a car person and english is not my native language so the terminology might be very off. I thank you in advance!

Sounds like the motor has lost it's permanent ignition supply.
Have you checked all the fuses?
I wouldn't think its the CCU at this stage.

Thank you for your reply! It crossed my mind and with my very little knowledge in cars, I think I managed to replace the correct fuse with a new one and the fault persisted. I'm not a 100% sure tho.

One might think the car service would've thought of this too? They also happened to have their "electrician consult guy" around that day and he actually was the one suggesting the fault being in the Multifunction module.

The Freelander 1 has a very primitive MFU (LR call it a Central Control Unit or CCU).
The CCU does have control of the wipers, but only really in a switch sensing role.
I'd check fuse 3 and fuse 8, both of which power the wipers through the CCU.

There's a relay on the CCU, which does wiper switching, but it's not replaceable except by someone good with electronics.

Edited for accuracy.

Due to me being uncertain about cars and my dad recommending to also check fuse 1, after replacing fuse 1 with a new one, the fault seemed to be lifted! I ran drizzle for 15 minutes and it worked as intended. This hasn't been possible for many months.

Thank you very much for your support and making me go back check the fuses!
