Changing an electric window regulator

To begin, you will need to remove the door trim. To do this, you must first remove: the rearview mirror cover, the handle outline and the speaker cover, leveraging with a flat screwdriver, very gently so as not to break the fasteners.

As with all work on your vehicle, remember to switch off the ignition, it is more prudent to also connect the battery (not necessary here)

Remove the speaker (4 T20 torx screws), disconnect the terminal.

You must then remove the baguettes around the glass. First the one exterior, then if you have the space this one interior (otherwise you can remove the inner one at the same time as the trim in the next steps).

You have to drag a flat screwdriver underneath and lever, taking care not to scratch the paint and especially not to twist the rod because these are very difficult elements. fragile.

You need to unscrew the 4 screws (2 torx T20 and 2 torx T30) that hold the trim in place. 1 next to handle, 1 at the level of the'armrest (hidden below), and 2 at the level of the speaker.

You must now pull gently on the filling for the unclip and try to break as few fasteners as possible (white clips), there are 7 in total distributed around the periphery of the part. Detach these white clips from the metal frame using a screwdriver and pliers.

Please note that the white clips are designed to be systematically replaced in the garage when this operation takes place (if they are broken).

Now you need to remove the insulating veil which is glued all around the door. Pull the veil slightly and use a cutter to cut the polyurethane foam which serves as glue

You will normally not be able to remove the veil while the handle is still attached (unless it has torn). See the next step...

At this point you can see the window and the window mechanism, but you still can't access it, you have to remove the handle.

You will need to use a drill with a 5 mm diameter metal drill bit. Drill the rivet which holds the handle to the door (use a 4mm drill bit if the 5mm is too big to properly drill through the rivet completely)

You must now unclip the 2 little ones blue ties which hold the 2 rods of the door opening system. Use a flat screwdriver to lever.

You can finish removing the insulation veil once the handle is removed.

You have just removed all the elements that were blocking your access to the window lift system. You must now drill the 5 rivets (marked in red, at the end of the arrows) that hold the window regulator rails to the door. Use the same method as in the previous step.

Two of these rivets are hidden behind the foam pads, peel them off to access them.

You need to remove the last white clip that holds one of the window regulator cables, by pinching it and pressing on it with a screwdriver

Last steps before removing the window regulator from the door. You must detach the sons which are located under the engine, held by a black clip.

Then unplug the power lug of the window lifter motor, use a small flat screwdriver, the operation can be difficult because the part you have to press on is towards the inside.

The most delicate operation consists of detach the glass of the 2 white brackets that connect it to the window regulator rails (one on each rail). Use a small screwdriver to press on the white plastic part located in the hole. Lever it to extract it completely.

Once the window removed from its supports, nothing is holding it anymore. you must remove it completely from the door. If you are not careful, it can break, CAUTION VERY FRAGILE!

Once the window is removed from the door, remove the window regulator, taking care not to damage the electrical cables (VIDEO)

In the video, the window was left in the door during this step, but it still had to be removed from the door for the next step. We therefore advise you to remove it to avoid any risk of breakage, the window regulator will be that much easier to remove.

You can now identify the fault.

In most cases it will be necessary to replace the window regulator system.

Disassemble the motor to put it on the new system if it is not supplied (3 Torx screws)

Mount the motor on your new window regulator (if necessary), grease it with universal grease (thick grease) and place your new window regulator in the door in the intended location. Check that it is working properly before the next step: connect the electrical terminal, switch on the ignition and press the button.

Remember to turn off the ignition before continuing.

Position the electrical cables correctly before any fixing. Equip yourself with a rivet pliers to fix the rails and the motor (5 rivets in total). Choose a rivet of suitable size and length.

Attach the electrical cables to the designated locations and secure the white clip of the window regulator cross cable (from the inside of the door).

Put the screw back in place, always being very careful. It must be aligned at the front in the rail fixe (blue arrow) and reclipped onto its 2 white plastic supports.

When handling the window in the door, you should always have one hand holding it from underneath to prevent it from tipping over and breaking the window.

Start by putting on the insulating veil on the 2 opening system rods.

Position the handle in its location, hold it well and engage the rods one by one in the blue ties of the handle by forcing slightly.

Before fixing the handle, you must test for proper operation of the door opening system, as well as the central locking system (if the vehicle is equipped with one). If you notice a problem, you must remove the rods from the blue fasteners and repeat this step until the system is working properly.

Bring your rivet pliers and fix the handle (1 rivet).

You need to put the insulating veil, to do this, simply press on the bonding area so that the foam makes contact again.

Before repositioning the lower part of the veil, remember to bring out the speaker cable through the hole provided for this purpose.

You must start by putting the inner baguette.

Then position the white clips that you had recovered during disassembly in the “U” locations provided for this purpose on the trim.

Clip the trim to the door starting from the bottom. Before clipping the upper part, fit the trim into the baguette (it will be difficult to do this once the clips are already in).

Screw the 4 Torx screws of the trim.

Plug in and screw it back in speaker.

Go back up the handle outline, the rearview mirror cover and the speaker cover.

Finally, go back up the outer baguette. You have to raise the window, and start by pushing the front part, pressing it from one end to the other with light pressure so as not to deform it. There is a deceiver which tells you whether you are well aligned or not.

You have completed your window regulator change.
