Could not have been an easier replacement process on a 2003 Buick Lesabre. Remove two screws and gently pry out center plastic clip to take off the kick panel under the glove box, disconnect power connector from the kick panel and set aside. Unplug the OEM blower motor power supply, remove 3 screws which secure the motor, slip it out carefully around wiring harness, remove rubber hose from OEM part and attach to replacement part, insert replacement part being certain to attach rubber hose, replace three screws to secure the motor to housing, reattach power supply to housing, retrieve kick panel and reattach power supply, and finally secure kick panel with center clip and two screws. Start to finish time was just under 12 minutes. Would have taken less time if not working completely upside down during replacement process!
