Any ideas what could cause my power windows, tachometer, speedometer, fuel, oil, volt, and ac fan to fail? My car seems to run fine and all the lights, radio work. The continuity for the FL30 fuse and the F11 gauge fuse, and all the fusible links were fine. Any help appreciated? Are they additional fuses besides the fusible links on the positive battery terminal, fuse box on driver side under the hood, and the fuse box just to the left of the steering wheel inside the car? Thanks, mitch
