First take out the door trim and seal adhering to the window. With a curved tool, take out the two moldings on top of the door. Open the window and move the glass out from the top of the door, taking care as you lift it upward and tilt it until it clears the pulling channel at the bottom. Unscrew the window regulator mounts and pull the window regulator out the opening on the large access hole on Sidekick, X-90, Vitara, and Tracker editions. Light oiling (using a lithium-based grease) helps all moving parts work smoothly when you're installing the window regulator and guide channel. You install the window exactly like you removed it. When the window is in place, close it completely. Move the glass diagonally until its upper edge lines up with the door's top edge. Then secure it with new tightening screws. Release the window regulator fastening screws, place the window glass until its back edge and top corner rest well within the doorframe rubber, and tighten the screws again to reassemble.
