Hello all...I am new to the forum and desperately need help. I have the problem as described above in the subject line with my 2001 Explorer Sport. I have all the typical symptoms...no lights as described above, but my headlights, brake lights, turn signals and interior dome lights all work fine. I have replaced both the headlight switch and dimmer switch. I have electrically checked every fuse in the block and every relay in the distribution box under the hood. When I disconnect the battery and then reconnect, the marker lights upfront, the tailights and the cluster lights all blink twice together but that is the only time they work. I am completely frustrated and stumped. Can anyone help please?
