This is a common problem, and there is a solution! Mine does the same thing.. You raise it once and one ram is lazy, so you lower it, and then they both go up the same speed. I've been meaning to fix it, but have been lazy.I have a dual ram setup for my hatch and sometimes one ram seems lazy.
Have to raise and lower a few times to get it to work. Is their
a relay or something that I need to make these work together consistently?
