YES! Rifgod1000. The forward window on the roadside in the lowest position, limps back to the almost closed position. It appears the arm is weak in that position but works rather well in the middle and high positions.
I am the 2nd owner, buying my trailer this year, so did not see your post of 2-11-17, until this morning. It is now May 10, 2018, fifteen months later. Did you find a solution to your problem? I would be ever so grateful if you would share your findings. If you haven't found a solution, perhaps we can solve it together.
