How do you change a turn signal switch on a Pontiac Grand Prix?

To change the turn signal switch on a Pontiac Grand Prix, first, disconnect the negative battery terminal to ensure safety. Remove the steering column covers by unscrewing the screws and gently prying them apart. Then, detach the old turn signal switch by removing the screws securing it and disconnecting the wiring harness. Install the new switch by reversing the steps, ensuring all connections are secure before reassembling the column covers.
