Have a 99 Rodeo and the 15a tail light/panel fuse pops within 3 seconds of turning on the marker lights. Have the tail light assemble removed, both of them and have the head lights disco'd as well. Even gone as far as removing the plate bulbs. Test the continuity at the fuse block and it is silent. Put a fuse in, new one, and pops with in 3 sec. Remove the now blown fuse and the meter screams. Have the lower half of the dash pulled apart and this is now aggravating. Anyone have any ideas as to what is going on here???
