WS6 headlight issue (not gears)
First, if they go up together, at any point, the motors work... For now.
Second, the wiring harnesses for the headlights are notorious for getting some corrosion (from rain). Unplug the clips and take a gander... If they are clean, move on.
Third, what happens when you press your alarm/lock button on the key fob... Do they go up for no reason?
Fourth, there could be a chance of the motors has just gone bad. Is there one that reliably goes up and down without a problem? Or is it both?
If it's one, maybe the motor simply **** the bed... Not a gear issue, but just for some other reason? I have installed defective headlight motors right out of the box... Ebay, I know.
#2. Unplugged them and sanded the ends and put dielectric grease on
#3. Lights don't go up and down with key fob. Gears were replaced a month ago with brass gears.
#4. Both were working today now neither one will go up!!

I had the problem on my car and discovered that my driver side tab had a small groove worn in it. I pulled it off, turned it around, and slipped it back on. Works good now. If the tab is completely gone, which sometimes happens, simply get a small length of fuel/heater hose.
Good luck.
