Here's a little tip to help you guys out if your motorized hatch is intermittently working... As long as you motor completes it's cycle and you hear the click when it stops, this will work for you.
Since I am too lazy right now to order a replacement reverser switch for the hatch motor, I have a qucik lil rig that might help out others with the same problem.
If your hatch motor is intermittenlt working, then more than likely the contacts inside the reverser switch (the black module attached to the motor w/ one screw) have a loose connection inside. take a drill, or just bore out a hole w/ a knife in the plastic interior panel right where that reverser switch is. Make it large enough to git a screwdriver into it, then anytime your pulldown motor decides it doesn't want to operate, just stick the screwdriver into the hole and tap that reverser switch a couple of times and she'll run again....Hope this is of use to someone...
