I have a 2000 Legacy L wagon. When I use the turn signals, they work fine, the lights flash, everything is nornal. But once the stalk returns to the off position, I hear a fast click like a double speed turn signal click. The turn signals are off but the clicking is still going except it is twice as fast as normal. If I jiggle the turn signal stalk it will stop clicking. Sometimes it starts clicking while I am driving and without having used the turn signals at all. Also, if I touch the turn signal stalk it will start clicking until I wiggle it. What do you guys think is wrong? Thanks!
