Annoying wipers!
Discussion
I think my ribbon cable also needs replacing. Any tips for removing the steering wheel with disturbing the nylon collar on the column appreciated. I had a right mare when the ribbon cable went kaput last time. If the nylon collar is disturbed the steering wheel boss grinds when you turn the wheel.
Thanks fellas,
I'm not looking forward to the ribbon replacement - fiddle jobs always seem to get worse!
I've also now realised that turning right will activate the wipers every time. For example, if the wipers are on intermittent, then on turning right they will go to the next stage of on at medium pace, then on the next right turn go fast! Blinking annoying!
I will check the control box for water ingress first - fingers crossed.

Condensation (i.e. little puddle of water) gathers in the lowest corner of the control box.
When you get intermittent wipers or odd behaviour it's usually because the little puddle of water got splashed up on the pcb in the control box, shorting the components.
It usually coincides with a bumpy drive or something out of the ordinary in terms of usual driving. Like a track day or similar.
If you remove the control box try to keep it in the same position so as not to spill the water on the pcb.
I drilled a hole on the lowest corner of my (replacement control box) to let any condensation drain out.
If you open the box you will see where the water gathers. It causes the pcb copper to oxidise and turn green.
It's that simple.

Thanks for the info Aide,
Strange that water even gets near the control box also. I will check it out tomorrow. Just wondering where the
I actually keep the car pretty dry at the moment so I'm actually scratching my head as to where any water could have got in as she has been dry since February.
Im leaning towards a ribbon issue if I'm really honest.

Just to repeat it again... It's condensation.
You have hot and cold air hoses beside each other under the steering column. With the control box in the middle.
Over time (years) moisture gathers inside and pools in the lowest corner of the box.
It's not enough to short circuit the pcb and just sits there. But when sometimes the buttons on the steering wheel start behaving funny it's because some water has sloshed up onto the corner of the pcb. Which shorts the pcb tracks in random ways. This can be caused by thrashing the daylights out of the car on bumpy back roads for example. Once it's left to dry everything returns to normal.
When I opened up my box the lowest corner was all gunked up with green oxidation from the pool of water and copper on the pcb.
I drilled a drain hole to solve the problem.
HTH and hope you find the cause of the problem.
