hello,im brand new here.I have a 2000 expedition that has the abs light on.What is the most common cause of this?the odometer also fails to light up (delay) for sometimes 5 minutes also shows 101,000 miles.Thanks in advance

have seen many clusters go bad causing the odometer problem. most common problem we see at my shop is rear speed sensors (mounted in rear diff)

Thanks I replaced the speed sensor and fixed that problem.How big is the instrument cluster problem,and how much $$$?
