This happened to me last year
This happened to me last year a few months after I bought a new 2016 Ram 1500.
Dealer replaced the two plastic clips that hold the glass to the regulator arms.
Someone suggested that I carry a roll of duct tape and a piece of cardboard in case this happens again away from home. I hope Ram is listening, and someone doesn't have to sue them to get a permanent solution to this problem.
Can you imagine coming back to your vehicle after shopping, only to find your truck full of rain/snow--or worse, some criminal waiting inside! Wake up RAM (BIG LIABILITY case waiting to happen)!
