My wife drivers a Corsa C, but over the last few months, it has developed a fault with the intermittent/once wipe setting. When you set the stalk to intermittent, it starts the wipers going but then they stop half-way across the screen. The only way to get it to park correctly is by moving the stalk a few times.
The wipe action works correctly on full and fast wipe.
Does anyone know what the peoblem might be?
