  1. Start by disconnecting the battery. Airbags are inside the door panels; tampering with them while the electrical system has not been discharged could cause them to deploy and injure or even kill someone. After removing the battery, wait for fifteen minutes before beginning work.
  2. Wear thick gloves when working on the razor-thin metals of the door panel, as they can cut you if you are not careful. Also, be sure to wear safety glasses while drilling; metal shavings can fly into your eyes, damaging them.
  3. Next, tape the window to the top of the door with light-stick tape that will not damage the paint.
  4. Remove the interior door panel. Remove the plastic retainers around the outside of it using a trim tool. Then remove the two bolts in the center of the door panel.
  5. Pry the door panel carefully by hand by pulling it away from the door. Once the panel pops off of the metal door, pull up on the panel to get it off the window sill and above the door locks. Angle the panel so the back of it can be seen; the door latch cable will still be connected to the handle on the panel. Work the end of the cable out of its slot.
  6. Next, drill out the rivets around the perimeter of the inner metal door panel. Once all the pins have been drilled, the panel will move, but this panel has tracks on the back that mount to the glass.
  7. Use a Torx bit and ratchet to unbolt the track of the inner metal door panel from the glass. Work the glass out of the mounts, and reach your hand through the speaker hole if necessary to move the track. Pull the inner metal panel out, and pull it up and over the door lock to remove it.
  8. Remove the tape from the glass while carefully holding it through the opening of the inner door. Be careful not to drop it and slide the glass down. Turn the glass 90 degrees with the smaller end facing up, pull the glass straight up, and out the door.
  9. Reverse this procedure to reinstall new glass in your vehicle’s door. Be careful not to over-torque the mounts to the glass. Use a rivet gun and rivets to reinstall the inner metal door panel. Don’t forget to reinstall any door cables or plastic retainers! Reconnect the battery and test out your window. You are done!

Where can I get replacement glass for my vehicle?
