Q: How do you remove and replace the radio and speakers on Chevrolet Express?
A: To remove the radio, first disconnect the cable from the negative battery terminal, then remove the instrument cluster bezel. For models from 2000 and earlier, depress the two radio retaining tabs to detach the radio from the dash; for 2001 and later models, remove the retaining screws before pulling the radio out of the opening. Disconnect the electrical connectors and the antenna from the radio, then remove the radio, with installation being the reverse of removal. For front door speakers, remove the door trim panel, disconnect the electrical connector, and remove the four speaker mounting bolts to replace just the speaker. If access to the window regulator or other components is needed, drill out the four rivets to remove the speaker enclosure. Installation is the reverse of removal, and short, self-tapping sheet metal screws can be used instead of rivets. For front door tweeters, remove the door trim panel, disconnect the electrical connectors from the power window, mirror, and lock switches if equipped, then disconnect the tweeter's electrical connector. Drill out the tweeter mounting rivets to remove it, with installation being the reverse and using short screws instead of rivets if desired. For rear speakers, remove the rear speaker trim panel and the rear speaker enclosure by removing four nuts. If accessing something else, disconnect the main speaker harness electrical connector, and if replacing a speaker, disconnect the speaker connector and remove the four mounting screws. Installation is the reverse of removal. For rear door speakers, remove the rear door trim panel, drill out the speaker mounting rivets, pull out the speaker, and disconnect the electrical connector, with installation being the reverse of removal.
