The windshield wiper switch on a Buick LeSabre powers the windshield wipers, the cruise control and the turn signals. When this switch dies, you can replace it with a working switch from the Buick division of General Motors. Most GM dealerships have a parts department that you can order a new switch from. You may be able to purchase a replacement switch from some auto parts stores, however.
