We are a team of ASE certified mechanics that have created this guide to help
you save money while doing the job yourself, or at least see what you are paying
for when having the job done at a shop. A window regulator and motor is the mechanism
inside a door or tailgate that holds the window in place while it travels upward
or downward when commanded by the window
What Goes Wrong?
There are mainly two kinds of window regulators, the first type uses a scissor-like arrangement with a ring gear and an electric motor with a pinion gear to drive
it. More modern types use a cable drive system whereas a series of pulleys
are supported on a framework or single main support rail. The motor is fitted with a clutched
wheel that drives the cable in both directions. In time these motors can burn out
or the cable system can break down hindering the window operation, this is usually
due to excessive resistance inside the window track which should be cleaned.
How Much Does It Cost?
Typically replacement parts will cost between $50.00 and $80.00 on Amazon (US) and will
require the removal of the door panel.
Labor time can be between 1.5 and 2.5 hours at a shop or dealer. If exact times
or procedures are needed you can ask our experts to
supply you with the information (free), or consult an online resource such
as AllData DIY (pay)
but this guide and video will be sufficient in most cases.
Let's Jump In
To access the window regulator and motor assembly the
door panel must be removed. This
is done with the door open with the window in the up position if possible. If
the window will not go up don't worry, once the door panel is off we will be
able to lift the window up manually.
There will be a plastic door liner designed to keep water
and moisture away from the door panel. Gently remove the plastic cover
and set it to the side.
There will be access holes which are used
to service the regulator, mounting bolts attach the window to the regulator framework.
In this case the bolt size is 10mm. If the regulator is burned out and not working
reach inside the door and use a small wrench to remove the bolts. In some cases
the window will be down inside the door which can be raised up manually and
held in place.
Remove the window mounting bolts from the window regulator, once the
bolts have been removed the window will become loose in its track, be gentle
with the window.
Grasp the window and pull upward, it will slide with minor resistance until
it contacts the upper portion of the frame, do not allow the glass to fall back
down inside the door.
While holding the window in place, use masking tape to secure the window
at the top of the frame. This step keeps the glass out of the way and safe while
removing the regulator and motor.
Locate and remove the window regulator mounting bolts, then gently allow
the regulator to sit inside the door until the motor is removed, (in some cases
the motor is attached separately).
Locate and remove the window motor mounting bolts, in this application
the bolts can be loosened which will remove the motor by moving it upward.
There will be an electrical connector attached to the motor which can be
accessed before or after the motor has been removed, whatever ever is easier,
press the release tab to disconnect.
Remove the regulator and motor assembly through the large door access port.
Use care when working inside the door because the door "skin" is the outside
of the door, if damaged (dented) it will show up on the outside of the car door.
This is what the window regulator and motor looks like once it is removed,
yours may vary.
Watch the Video!
Please watch this video of the job being done, then continue down the
guide to glean additional helpful information.
It is important to match the old unit to the new replacement part, this
will ensure a proper installation, also check the electrical connectors as well.
Gently feed the new motor and regulator assembly back into position, this
can be a little tricky so hang in there.
Once the motor and regulator have been repositioned, re-install all mounting
bolts leaving them loose until all bolts have been threaded.
Using a ratchet or wrench tighten the motor and regulator mounting bolts.
Don't over tighten, these are small bolts and don't need hulk-like strength
to reassemble. There is no torque spec for these bolts but in general it would
be between 3 and 5 pounds.
Feed the electrical connector from the window motor through the access
hole and reconnect it to the door wiring harness, you should hear a click
which tells you it is fully seated.
The window is ready to be lower back into place, while holding the window
firmly and remove the masking tape to lower the window onto the new regulator
cradle. Clean the side window tracks with soap and water if necessary, this
will help the window operation.
You may need to turn the ignition switch on and work the window switch to
move the regulator cradle into position so the window mounting bolts can be
installed. Keep your fingers and hands out of the way. Thread in and tighten
the mounting bolts, again these don't not need to be super tight. If the window
is non operational start by checking
Now that the job is complete, test the window operation by working the switch
in both directions, the window should work smoothly while not causing the motor
to labor. In some cases there are minor adjustments for the window rails to
be re-position, check the vertical operation for hard spots or clicking noises and
adjust if necessary.
