  1. step : Removing the Door Pull (1:05)
    • There's a little inner panel on the door pull. Using a flat blade screwdriver, pry that out right in the middle and take it out carefully.
    • Using your flat blade screwdriver, pry up the back of that door pull panel. The sides and front of the panel are secured with clips, so pull them up.
    • On the bottom side of the panel, there is a connector. Just press a tab and pull the connector free.
  2. step : Detaching and Removing the Outer Door Panel (1:39)
    • After removing the door pull, you'll notice there are three Phillips screws that hold the panel to the door.
    • In addition to those three, there are two T25 Torx screws on the bottom of the panel that hold it to the door.
    • While being careful not to drop them, remove the three Phillips screws.
    • Then remove the two T25 Torx screws from the bottom.
    • The panel is now held on by a number of clips along the sides and bottom. Using a door panel clip tool, or a putty knife, pry the bottom and sides of the panel away from the door.
    • Pull the panel up and out slightly.
    • To disconnect the door handle, pull the door handle out a little bit as you're opening the door. Push the small hook up and slide it through.
    • After your door handle is disconnected, there's a series of harnesses which all have small tabs. Push down on the tabs and pull the connector out.
    • The only difference is the courtesy light at the bottom of door which has small ears that you need to pry out with a screwdriver and pull them down.
  3. step : Securing the Window (4:40)
    • Pull the window up, stopping a few inches below the top of the frame.
    • Secure the window with some painter’s tape.
  4. step : Removing the Harnesses (5:10)
    • There are several clips holding the wiring harness in place against the door panel. Remove these clips, and then disconnect all the harnesses.
    • For the window motor harness, there is a tab which you pull down before pulling off the harness.
  5. step : Detaching the Window (4:50)
    • On the door panel, you'll see two circular black covers. Pop those out, and you'll see one 10 mm bolts under each. These bolts hold the window to the regulator.
  6. step : Removing the Interior Door Panel (6:16)
    • Remove all the 10 mm bolts along the edge of the door panel.
    • Once the bolts are out, take your flat blade screwdriver and start prying the panel away from the door.
    • Around the door lock, there are two rivets that hold it to the door panel. Push those through with a screwdriver.
    • Directly below these rivets, there is a tab for the wire harness. Squeeze the tabs, and push it through.
    • Take your door harness, push it through and lift your panel up and over your door lock.
    • Finally, there is a harness connection down the bottom with a tab on the left. Using your flat blade screwdriver to push the tab down, pull the connector off.
    • Once you get it off, pull that connector through, and make sure you feed your inside door handle cable through and bring it out the backside of the panel.
  7. step : Removing the Window Motor from the Door Panel (8:23)
    • Place the panel on a flat surface with the motor side down, and you'll see three T25 Torx screws holding the gear and motor to the panel. Remove those, and pop the motor out the bottom.
  8. step : Removing the Speaker (10:15)
    • The speaker is held on with four tiny rivets. Using a skinny punch, know the center of the rivet out. Taking your drill and aquarter inch drill bit, slowly drill the rivet out. Pry the speaker from the panel.
  9. step : Replacing the New Window Motor (8:58)
    • Taking your new motor, slide it under the panel, and make sure the motor faces up and away. Place the gear back on top, making sure the wires don't come out. Replace the screws, and tighten them firmly.
  10. step : Replacing the Speaker (11:08)
    • Using a small bolt and a nut, take the speaker and attach it to the new panel.
  11. step : Transferring the Plugs and Clips (11:29)
    • Pull the plugs out. For the clips, there are small ears on the backside of the panel. Squeeze those and push the clips out the front. Then reinstall on your new panel.
  12. step : Reinstalling the Window Assembly (12:00)
    • Pull your door lock up through the panel.
    • Reaching in behind the panel, pull your door latch cable through the panel.
    • Pull your wiring harness out from behind the panel.
    • Taking the door lock connector, push it through the hole closest to the door lock and reconnect.
    • Put your panel in place, and begin replacing the bolts.
    • Reconnect the power window motor and put the rest of the harnesses back in their places.
    • Finally, you can tighten up the bolts
  13. step : Reattaching the Window (14:46)
    • Put your key in the car, and, using the power window switch, move the regulator to a position where you can get to the two 10 mm bolts.
    • While holding the window, remove the tape and carefully slide it down into place. Make sure it's seated well.
    • Then tighten these two bolts.
    • Test the window to make sure everything is working properly.

Window regulator great product super fast shipping
This product fit perfectly easy to install following the you tube video only problem I had was reinstalling the two prong lock assembly plate theres such a small hole to stick your fingers in to pry the two rubber nipples. My mechanic quoted me $400 to replace the regulator I did it myself for $57 and about 2 hours of time.

Saved $500 repair window parts
After a quote of $600 to repair a nonfunctional window mechanism, we decided to try ourselves. Together with great YouTube tutorials and perfectly fitting parts, we were able to get that window working perfectly

02 Passat LF window regulator
Found the part I needed w/ no problem. The website said it was an exact match. Just installed it today and the site was right. It came as a complete unit. No figuring out anything on my part. Saw on another site the parts came in a bag and you have to use the orig inner panel and rails. Don’t know if anyone else is familiar w/ vw but there is a gasket around the outside of the inner metal panel that was not included in the bag. The problem is it gets destroyed when you pull out the inner panel let alone it was rotting through and leaking already so your only hope is to run a bead of silicone around the inside edge or use it as is because I don’t believe the dealer has a replacement gasket for it. Glad I found the part I needed here. It was a quality part. Came complete and already put together. And it was an exact fit. No issues whatsoever. Will shop here from now on and tell everyone else about it.

Good fit and saved me a lot of labor charges
My wifes 1999 VW Passat suddenly had a problem with the window falling into the door. Tried to replace just the regulator carrier pieces the window rests in, but found one of the regulator rails had popped out of its rivet mounting. Ordered a new regulator from here after shopping around, and just put the new one in. Works great! Installation video VERY helpful in avoiding mistakes in installation/window motor changeover. Fit was good, and I saved a lot of labor charges by doing it at home. Thanks! The part was a lot less expensive than I had anticipated when I first started this project, too!
