Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.

Today, we'll be installing a passenger door lock switch in this 2007 Audi A4. You will need a flat blade screwdriver, a Phillips screwdriver, and depending on the vehicle's condition, you may need a flashlight, pair of pliers, a hammer, and some glue.

There should be a panel covering your battery. Remove that, and then disconnect the negative terminal on your battery.

Remove the trim panel using your flat blade screwdriver. Then locate the six Phillips head screws that hold the door panel on. There's one underneath the panel, four behind the trim panel you removed, and one underneath the arm rest. There should be a cap that you pry off to access the screw. Remove the six screws using your Phillips head screwdriver. The bottom screw sometimes doesn't come out. You can still remove the panel without taking it out.

Now, unclip the panel. Sometimes plastic clips may come loose and fall out. We'll show you what to do with those later. Carefully pull the panel up and off, remove the door handle cable, and then use your flathead screwdriver to loosen and remove the harness from the window motor. Finally, remove the speaker harness from the speaker.

If the screw on the bottom of the panel didn't come out, use a pair of pliers to remove it. You might need to use a hammer to tap the clip back into the door. You might also want to glue in any clips that fell out during the panel removal.

Now, you can locate your door lock switch. Remove the wiring harness, and push the switch through.

Now push the new switch into place and reattach the harness.

Reinstall the speaker wire harness and the power window harness, and reattach the door handle cable. Make sure the lip of the door panel sits inside the groove of the door. Push the panel down firmly, and then lock all other clips back into place. Reinstall the six Phillips head screws. Finally, clip the trim piece back into place. You can now reconnect your battery and replace the panel.
