Q: How to service the Light Control Module on Buick Park Avenue?
A: Begin Lamp Control Module servicing by first removing the lower IP trim panel followed by removing the two fasteners securing the heater A/C duct then relocating the duct from the installation site so one can access the panel dimming control module bracket. First remove three fasteners holding the lamp control module bracket onto the instrument panel before releasing the two electrical connectors from the lamp control module. Set up the Lamp Control Module by connecting its electrical connectors followed by installing the bracket to the instrument panel then placing the heater A/C duct back into position with the two fasteners in place before returning the lower IP trim panel.
