Removal and installation of door glass (Opel Astra G)

Front doors

1. Remove the door trim panel and plastic insulating membrane (see Removal and installation of interior trim panels).

2. Raise the window completely. On models equipped with side airbags, disconnect the negative battery cable and wait at least 1 minute to allow the capacitor in the independent power source to discharge. Disconnect the wiring, unscrew the fasteners and remove the airbag sensor assembly with the support bracket.

The right sensor is different from the left one - do not mix them up when installing.

3. Drill out the rivets securing the rear window regulator guide channel to the inner door panel and remove the channel from the door frame through the hole.

4. On models with electric windows temporarily connect the regulator switch and connect the negative cable to the battery. On models with manual windows, temporarily place the window lifter handle on its axle. Position the glass so that the bolts securing it to the regulator are visible through the holes in the door. Remove the bolts.



5. Tilt the glass forward enough to release the window regulator roller from the rear guide channel, then lift the glass up and out of the door, pulling it outwards - you may have to move the glass with the window regulator due to the limited opening.
