I replaced the battery in my 2001 Sebring LXI. Next time I drove the vehicle I noticed the Speedometer and Mileage meter do not work at all. Also my gas gage fluctuates speratically within a quarter of a tank from where it should be (back and forth). Further more my Dash Display for direction, temp, est mileage, ect is stuck on stupid and does'nt move or give the correct info either. The dealership tried "reseting" the "motherboard" but to no avail. What is the matter with this car? What can I do to fix the problem? I am machanically inclined. Thankyou!
