My blinkers keep randomly going out in my truck. if i wiggle the fuse for them, they start working again. i have tried replacing the fuse several times: it still does it. i think the wire is loose at the fuse box. is that the problem, or is it something else? Could it be the terminal that the fuse goes in? how do i fix this? is there an easy way to get my fuse box out without taking me dash apart?

thanks,
chris
