Q: How do you remove and install a Window Regulator on Chevrolet Express?
A: Remove the door trim panel and the water shield. Unbolt the window glass from the regulator. Push the glass all the way up and tape it to the doorframe. On power window-equipped models, unplug the electrical connector. Remove the Door Handle and disconnect the lock rods. Drill out the rivets securing the window regulator assembly to the door. On reassembly, use sheet metal screws in place of the rivets. Remove the regulator from the door. Installation is the reverse of removal.
