My '02 1st gen Durango, 4.7, 4WD Sport has the same backup light issue. However, I do not see the switch pictured in a response, great picture, though. Any suggestions where to look for this switch on a 45RFE / 4WD auto trans. Bulbs and Fuse are good. Odd that both backup lights are not working, so it is diagnosed the Backup Switch is bad.
