So I turn my wipers on, and they will work continuously at full speed. I cannot control the delay, they will also not shut off. In order to shut them off, I have to put the key in the off position, then when I put it back into the ready position they will turn off. They turn on normally, but the only way to get them to go down is to put the key into the off position, plus I can't control the delay at all. Any idea whats wrong? It's really annoying me.
