Q: How to remove and install standard, manual remote, or electric remote mirrors for Buick Century and Regal?
A: For the installation and removal of standard, manual remote and electric remote side view mirrors, follow these basic steps. First, take off the door trim panel and inner panel water deflector, then pull out the front part of the glass run weatherstrip while holding down the glass. For standard side view mirrors, remove side view mirror base stud nuts from attaching nuts before removing the side view mirror. For manual remote side view mirrors, remove door trim panel and side view mirror remote control escutcheons also disconnect inner panel water deflector. Right-side remote side view mirrors may require detaching a portion of the instrument panel. Remove screws and bolts attaching front glass run channel lower retainer to filler, rotate retainer rearward till patch for noise control is removed to expose screw at belt's end then remove screw. At top front of window frame, remove filler attaching screws and then take out both filler and side view mirror from door. Disconnect negative battery cable first in case of electric remote side view mirrors as well as removing side view mirror remote control escutcheons, door trim panel, inner panel water deflector and electrical connector for side view mirror. Right-side remote side view mirrors may also require detaching part of the instrument panel. Follow these steps for all types of side view mirrors: Ensure that either side view mirror gasket or electric wire is correctly aligned; replace side view mirror including filler on door; set up filler attaching screws at top front of window frame; attach nuts on studs for side view mirror; put back screw at belt together with inserting patch for noise control; fasten front glass run channel lower retainer together with filler by using attaching bolts as well as screws; afterwards insert in place back part of glass run weatherstrip for the former step to be completed just behind it. In this case there should be electric wire routed around the front glass run channel retainer so that it could go into its clip if any type electric remote side view mirrors are installed through it. Nuts must be tightened to 72 in.-lbs or 8 Nm eventually.
