I have weird problem with turn signals. The right one works fine. The left one works fine when it is warm and dry. When it turns cold and damp, the left one will not come on and makes this awful sound, like a relay is stuck or something. Occasionally, I can fiddle with the stalk and make it work, but not often. Mechanics are at a loss, haven't tried the dealer yet. Any help appreiated as the weather is turning again!!
