Hello. I have a 2004 xlt 4x4 4.0. The hi/lo beams haven't worked since i bought it. The hi beam light stays on but I'm sure they're on low. No change happens when i use the lever to switch from hi/lo. About a month ago my wipers stopped working. They don't move at all when i turn them on. I've checked the fuses i think would be connected and they are fine. And last week my dash illumination stopped working. The indication lights work(check engine, hi beams, parking brake, etc), but other than that it's dark. I'm using a small flashlight to make sure I'm not going too fast or about to run out of gas. I can't find what fuses are connected to that. The hi/lo beams and the wipers are managed by the same control, the turn signal lever. Maybe that's it? Is there any way to test it to be sure before i buy one? I love my little truck but she's made me learn a whole lot more about mechanicking than i ever wanted to know. So anything you have that would be useful I'd greatly appreciate. Thanks
