How to Replace the Blend Door Actuator in a Defroster System on Buick Century?

In order to replace the defroster actuator, first remove the right instrument panel insulator panel and the i/p compartment. Next, remove the screws from the relay bracket and set it away. Unplug the two vacuum lines from the defroster actuator, and the orange vacuum line from the recirculator actuator, and apply it with a foot Vacuum Pump. Take off the defroster actuator from the case of the hvac module and using the hand Vacuum Pump, you will open up the door of the recirculation actuator all the way. Swing the defroster actuator to the right and up into the gap behind the dash and the hvac module opening, then remove it from the arm of the defroster door. For installation, insert the defroster actuator to the defroster door arm and snap it into the hvac module. Connect the vacuum line to the actuator, remove the hand Vacuum Pump, and reconnect the vacuum line to the actuation to recirculation. Screw the relay bracket and tight it to 1.0 n.m (89 lb-in) and install the i/p compartment and a right instrument insulator panel.
