2013 Ram 1500 wipers, windshield & visibility problems

My multi-function display on my 2013 ram 1500 has gone blank. This is a critical safety device because I have lost the use of my backup camera which is invaluable on this large vehicle. I have already bumped into small objects while in reverse, which I would not of if my display was working. And by the grace of god, I have narrowly adverted a more serious accident.

Bought the pickup in january 2016 one previous owner everything original the passenger side headlight connector pin needs tightened constantly because the low beam high beam loses connection and won't come on unless you pull headlight and tighten the connector pins. It happens at various times in various situations while driving it will also flicker on and off. Parklight works fine. I don't know actual date because it is so frequently so the date is an estimate.
