Replacing Power Window Regulator/Motor on 97-05 Buick Century
Here is how to replace a window regulator and motor in a 97-05 Buick Century. This procedure is similar in most vehicles. Sometimes the manufacturer uses rivets instead of bolts, but in that case you can just drill out the rivets and use nuts and bolts if there is room, or just replace the rivets if you have a rivet gun. This part only cost $50 (free shipping) from 1aauto.com for this application, and only took approximately 35 minutes to install.

What not to do when replacing a power window motor
When replacing a power window motor on a newer cable style regulator you
should NOT let the cable wheel get out of the transmission housing. We are
all human though so this video shows you what to do if you make this
mistake. This video is universal and applies to any make, model or year
with a cable style window regulator and power window motor.
1999 Pontiac Sunfire Power Window Regulator and Motor Replacement
Replacing a power window regulator and motor assembly is a bit tedious, but
not impossible with the right tools. Cheaper cars like Chevy Cavalier and
Pontiac Sunfire 1995-2005 have components riveted to the door. That's
really the worst part. Drill out the rivets and pop them out of the door
panel. Extract the assembly, mount a new motor or a new assembly with
regulator and motor (Recommended). Sorry for the video imperfections, but I
wanted to get this uploaded for anyone else trying to do this job and not
knowing for sure what all is needed to be done (like me!). But we got'r
done. Have fun! By the way, these parts are relatively cheap - $30 for
motor or $50-60 for complete assembly with regulator and motor. Also, be
sure the window tracks inside the door are in place and lubed with WD-40.
If using your original regulator, grease up the slide rails to prevent
jamming or strained operation (which can burn out a motor).
Automotive Repair: Power Window Troubleshooting
Imagine the convenience! Just push a button and the window goes down all by
itself. This luxury item used to be reserved for only high-line cars many
years ago but is now the standard. For years, the window switch had a
direct path to the window motor and when the system didn't work,
troubleshooting was usually pretty straight forward. Today, though, that
window switch may go to a computer instead, requiring the tech to review a
little tech info before he even starts pulling door panels.

of the trade to help you make short work of repairing today's power window
systems. Click this link to subscribe to Motor Age!
