Sorry Stuart, I was not clear. The set screws came right out but the handles wont budge.
I have soaked with WD 40 but you cannot really soak them except throught the set screw hole.
I dont want to wreck my window regulator or latch release.
Should the handles come off easily once the set screw is removed. All 4 of mine wont budge. Am I missing some other fastener?
