When I turn my parking or head lights on, my left turn signal comes on and stays on.

I pulled all the cloth out of the trunk and figured out that the turn signal control box (maybe a relay) is in the trunk. It's on the driver side, just under the forward part of the left panel. When I pulled up that little carpeted panel and look on the front edge, I could see a bracket with a blue relay attached to it. So I pulled it off the bracket and gave it a wack with my screw driver handle and it started working properly again.
