Could be a possible wire problem.
But to get to that front one, you have to remove the air deflector and the splash guard. Just a few bolts to remove, then give the splash guard a tug to get it loose from the holding clips, and there ya go. There are 3 retainer screws in the bulb housing that you will have to remove before taking the lens out of its mounting tray. I had to do it to install my clear corners.
Here's a site with pics to reference on a 95 Z, but it should all be the same I think.
