I have an 08 street glide, the left turn signal isn't operating properly. The left signal comes on by itself and the only way to shut it off is to turn on the right turn signal. At one point the left turn signal would go out using the left switch, now the left switch doesn't operate the turn signal at all. The turn signals do blink when the security mode activiates. Is this a tssm module problem or something else. Thanks for any and all help resolving this issue before I make a trip to the dealer
