To replace the blower switch in a 2003 Chevy Trailblazer, first disconnect the negative battery terminal to ensure safety. Remove the dashboard panel surrounding the switch by unscrewing any screws and gently prying it off. Disconnect the wiring harness from the old blower switch, then remove it from the dashboard. Install the new switch by reversing the process, reconnecting the harness, securing the panel, and finally reconnecting the battery.
