Hi, I hope someone can help with this. I've done a search but can't find a definitive answer. The car is my son's 97 1.6 AFT GL, the wipers have stopped parking and only work on the fast speed. He's just fitted a brand new stalk assembly today but the problem persists

. I've read that it could be a relay but we don't want to spend more cash in case it does not fix it

.
Any advice would be welcome, thanks in anticipation.
