Removal and installation door glass (BMW 5 Series E28)

If your car radio is equipped with an anti-theft system, make sure you have entered the correct code before disconnecting the battery cable. Refer to Section Anti-theft audio system and instrument cluster language before disconnecting the wire.

If after connecting the wire, the inscriptions on your instrument panel appear in a language other than the one you need, refer to Section Anti-theft audio system and instrument cluster language, which describes the procedure for installing the required language.

1. Disconnect the negative battery cable.

2. Remove the door trim panel and plastic seal (see section Removal and installation the interior door trim panel).

3. Remove the inner and outer sealing strips from the door.

Front door

1. Raise the door glass enough to access the mounting bolts through the access hole. On models with power windows, temporarily disconnect the battery cable to do this.

2. Support the glass and loosen the bolts securing the glass to the window regulator.

3. Lift the glass up until it comes out of the window opening, then tilt it and pull it out of the door.

4. Install in reverse order.

Back door

1. Perform all operations described in points 1-3 and 1-2.

2. Loosen the rear window guide mounting bolt.

3. Unclip the glass from the front roller guide, disconnect it from the guide rails, then pull the glass back and remove it by grasping it from above.

4. The fixed glass can be removed by loosening the guide rail bolts and then pulling the rails down and back to release the glass.

5. Reinstall in reverse order. The rear window can be adjusted by loosening the adjusting bolts and then lifting the window to a height of approximately 3 cm from the top of the window opening. Adjust the distance between the glass and the opening so that it is the same along the entire length, and then tighten the bolts securely.
