So after doing a new headliner in my 1992, the dome light will not come on, with door open or by button, the door chime is not coming on and there's no power at my academy player. I'm not sure what I would have done to cause this while doing the headliner. The only wiring I touched was the wires for the non working lighted sun visors that I clipped, but I doubt that they are on the same circuit. I also checked the fuses and they all seemed good. I've had an issue with my amp losing a ground, but when that happens the head unit still had power. Now the amp will not come on , because the head unit isn't signaling it to. Any ideas?
