I Have a 1998 Ford ranger 4x4 and both 4x4 high and 4x4 low lights are flashing on and off 5 times each time they flash. This happens as soon as I start the truck and about every 5-10 minuets thereafter. When this started, the fourwheel drive quite workin and. I replaced both front wheel hubs and nothing still. There is no Check engine or Check guage light triggered. Any Idea?
