Here's where the lubes come in, my general rule is if it pivots, use spray grease (chain or white lithium). If it slides (window guides) use a liberal amount of silicon spray. And use the grease on the window regulator gears. Be especially sure to get the spray grease on all the door handle mechanism pivots, and the window regulator pivots. The contact cleaner is good for cleaning old gunk off. This rear passenger window barely went up and down when I got it now it is good as new. |
