    Q:
    How to remove and install the Headlight Switch on Buick Century? Posted by Customer
    A:
    Users need to pull the back edge of the left instrument panel access cover to free its retainers using a plastic flat-bladed tool. You must loosen the forward edge of the LH IP access opening cover by accessing it behind the hinge pillar so you can remove it. The headlamp switch retention screws must be unscrewed followed by a methodical outboard removal of the switch to reach the electrical connector which can then be disconnected. Connect the electrical connector to the headlamp switch and then position the switch tabs onto the IP before pressing it into its final location. Secure the retaining screws on the headlamp switch while torquing them to 1.8 N.m (16 lb in). The final installation step consists of mounting the LH IP access opening cover forward edge into the hinge pillar slot while securing the retainer mechanism to the IP trim pad holes through strong pressure.
