Renault Laguna Window Regulator Fitting Instructions
NB These instructions are a guide on how to remove and re-fit an electric window mechanism and are not intended to be complete. It was written some time after the job was done and some improvisation will be needed.
1. Removing the door panel
Pop off the door handle trim screw cover with a small flathead screw driver, then remove the retaining screw behind with a torx bit Tools required : T30 Torx Bit Small flathead screwdriver
Remove the triangular plastic trim located just off the picture by prying gently with a screwdriver to first loosen, then use your hands to work it out.
Locate the lower door panel screws as circled in the picture. Tool required : T20 Torx bit (star screw) Gently ease in and then pry the panel with a sizeable screw driver, starting at the outer corner then working around, as indicated by the arrows. The panel will be tough to pull off as it is held by i) Retaining clips and ii) heavy duty double sided seals.
Once the panel is released, lift upwards and pull away from the door just enough to get down the back. At this point unclip the cable connector to the back of the door handle. You should have enough play to move the panel to one side (by rotating the panel onto its side).

2. Removing the window mechanism
Firstly, its important to ascertain if the mechanism is jammed. If this is the case, then do not use the switch to force the window down. This will damage the motor pulley further! a) If the mechanism is jammed the two cables leading to the pulley will need snipping (cable cutters, vice grips, etc). The cut points are indicated by the red arrows; the second picture shows the reverse of the mechanism. [The glass is now free to drop so caution is advised!] If the mech is not jammed then wind the window down (using the switch). b) Drop the glass so that the blue clip is roughly at the point of the yelllow yelllow ye ow arrrrow. arro w a ow c) Disconnect the plug to the motor, circled in orange d) there are two plastic retainers to the back of the blue runners, each with a little lip on the side nearest to the centre of the door. Give these a wiggle and pull towards the centre of the door, then the glass can be worked off the runners. There are sticky pads between the glass and the blue runners, so bear this in mind when working off the glass e) slide the glass carefully back into the closed position and support using a wedge or similar

Unbolt the 5 nuts circled in green. The mechanism is ready to be freed off. This can be difficult and sometimes manhandling is the way to do it, but basically : a) release the lower bolts from their mountings. b) Work out the top bolts by wiggling and twisting the two metal runners inwards, effectively folding the mechanism on itself. Take care not to catch the bottom of the glass when freeing the top bolts as they are in close proximity. c) Remove the mechanism from the door. Dont snip any cables !! if the regulator appears to be caught, its more than likely the retaining clip has not been released (its positioned on the inside of the door) this is shown by the red circle. Check the door inner for remains of the mechanism such as cable tensioners, retaining clips and the like see the Parts document for more info on these. Its not very technical but the best way to secure the window is with a length of wood, or zip ties (up and over the inner door lip, through the holes in the bottom of the glass and tie) or both

3. Refitting

Generally, refitting is the reversal of removal followed by resetting the automatic memory (described in section 3), however ensure you read the following : IMPORTANT ! : If you plan to test the mechanism freely (without the glass), ensure that the blue slide clips are more or less halfway up the runners. The mechanism will move about 3inches each press prior to the switch memory being reset. If these clips jam on the top (particularly as the glass acts as the stop) or bottom, the mechanism WILL break and I accept no liability on for any damage caused here.
4. Resetting the window memory
Following re-installation and re-fitting of all cables please note that the window will only inch up. This is normal! You must follow the steps below to re-set the memory for window motor; a) Gradually inch up the drivers window to the fully closed position -take care not to press the button too many times as this will ultimately snap the cable and/or clip b) Fully close the passenger front window c) Lift both the driver and the passenger window buttons simultaneously then hold for approx 4 seconds d) This should re-set the mechanisms memory and normal operation will resume

Renault Laguna Window Regulator Parts to Send & Damage Check
The following is a list of the parts making up the regulator to send for repair. Generally the unit will be removed almost complete, so Ill highlight the parts that you have to watch out for. Its always an idea to check inside the bottom of the door once the unit is out paying particular attention to the parts below.

Parts Check

1. Complete Unit
This is pretty much the whole thing, including the motor on the back. Yours will most likely have the parts hanging off/fell off due to snapped cable.

2. Tensioners x2

There are 2 of these, each comprising; White housing Black cable end Spring
These have the habit of dropping off and falling into the door. Ensure you dont loose them as the unit cannot be repaired without them! Lost springs are ok, and a missing black cable end is not the end of the world, but the original parts make for a better repair.

3. Cable Seating (Grey Plastic)
This will probably still be in place either on the frame or on the end of the cable. This sometimes comes off and drops in the door so again have a good look.
4. Slide Clips (Blue Plastic) x2
There are 2 of these. They should be still on the frames. Sometimes they are snapped as circled, however this damage can be repaired.

Damage Check

1. Pulley Wheel
These photos are as-is from a regulator that came in for repair, showing the damage to the pulley. In this case its not too bad and is fully repairable. Before sending in your regulator itd be an idea to email me photos from the same angles to assess if its good to repair or not.
