I'm a newbie, so if you can help, please do: 2000 TJ 4.0. My left turn signal started 'acting up' and eventually flickered rapidly every time I used it. At that same time, I lost use of my dash light and the parking lights. I assumed I blew a fuse and a bulb simultaneously. I was wrong. I changed both and nothing happened. Is there another fusebox other than the one behind the glove box?
