I've got a problem with the front turn signal/park lamp on a 01 WS6. The turn signal is fine, but when it's supposed to be in while in idle, it won't go on. The right one is fine but the left one is screwed up. Like when you press the unlock on the remote, the right one flashes but the left one doesnt. When you turn on the headlights, the right one is on and the left isn't. I changed the bulb, the socket and still nothing. Can anyone help me out?
