Three arms needed to roll window down.

[R.L.]

Well maybe not three but two was a must to pull up on the glass while cranking the window open or close.I've put up with it for a couple of years, I expected to change the regulator when I put new rubber and seals in my doors but just for the heck of it this morning I got out a can of silicone spray lube I had in the shed for some time and I oiled everything I could get to and guess what, the window works now; still needs the seals and rubber but you can work the window up and down one handed. Go figure the easiest fix is usually the best. I hope it'll last, if not I will try a heavier grease.
