As many of you already know, the door lock actuators in your 2007-2014 GM vehicle are very unreliable.  Most units suffer motor failures which can make locking and unlocking the vehicle very cumbersome.  GruvenParts.com has been repairing the faulty GM door lock actuators since 2010.  Our new motor is a reliable high torque design with factory correct wiring inputs. Our motor has passed rigorous 35,000 lock/unlock cycle testing runs conducted continuously over the span of 2 full weeks.  Please read the repair options listed below before ordering.

Repair Options

  • Buy Motor Only and Install it Yourself and Save $$.  You can also choose to have the motor shipped with a new brass pinion gear preinstalled - this will save you the hassle of removing the old gear and pressing it onto the the new motor shaft.  Reference the repair instructions listed at the bottom of this page or watch the youtube installation video. Choose passenger side or drivers side from the drop down menu.  The motors are the same front to back, but they are different drivers side to passenger side.
  • Buy a Repaired Actuator : Our FAA licensed Airframe and Powerplant mechanics disassemble the broken actuators, clean and lubricate the core components, and replace the unreliable GM electric motor within the unit with our reliable high torque design. The repaired units are bolted back together using appropriate fasteners and can be easily re-serviced if necessary.  The repaired assembly is fully tested prior to shipping.  Please email Paul@GruvenParts.com with your actuator part number before choosing this option so we can ensure we have it in stock. You can call your dealer and provide them your VIN # and they will give you all your actuator part numbers. Remember : LF (Left Front) is Drivers Side Front, RR (Right Rear) is Passenger Side Rear.  You will receive a $20 core refund when you send your old unit back to us in repairable condition.  Please reference the address below.
  • Send Us Your Actuator for Repair : Send your actuator along with copy of your invoice to the address specified below.  We will perform the repair and send it back to you, usually within 1-2 weeks 
  • If you are located near Atlanta, we have a Certified GM Master Technician who can perform the installation on your vehicle.  Please email Paul@GruvenParts.com for details.

** Instructions for Installing Motor Yourself **

*** Click Here For the Installation Video !! ***  (thanks Fernando!)

To change out the motor yourself, do the following :

A. Drill off the 2 rivet heads holding the cable "L" bracket onto the actuator case and remove the cable "L" bracket.  The actual rivets themselves stay in place, you are only machining off the rivet heads enough to get the L Bracket off.  Some have just used a dremel tool with grinding bit to remove rivet head.  Be careful not to damage the surrounding actuator structure.  ** Users Note ** Some have drilled the small pilot hole into the rivet BEFORE machining off the rivet head.  This can help to ensure the rivet doesnt spin while drilling the pilot hole, since the rivet head is still there to hold it in place.  We machine the head of rivet off 1st, but you could also machine pilot hole 1st, either way is acceptable.

B. Put actuator in the locked position (as if door was shut) and remove the torx screws around the perimeter of the case.  This step is important because it moves the internal mechanism out of the way and allows for easier removal and installation of the case halves.

C. Remove the top of the case (the motor will come with it).  Unplug motor from top case.

D. (Skip this step if buying motor with pinion gear preinstalled).  Use a small gear puller (like the Walkera W010 Gear Pinion Puller) to remove the brass pinion gear from the old motor.  A puller for 2mm shaft works well, these are readily available on Amazon.com.  You can also place the old motor in a vice, and use a small pair of needle nose pliers to grab the back of the gear while tapping with a small hammer to push the gear off the shaft.  Do not damage the brass gear as it is reused.  Press old gear onto new motor shaft using vice or arbor press.  

E. Place the new motor/gear back into the actuator and ensure it meshes with the mating spur gear.  Ensure all metal filings are removed from the inside of the case.  Please note : our motors marked "CW" go in the drivers side actuators and "CCW" go in the passenger side actuators.  It is the same motor front to back, the only difference is side - passenger side is CCW while drivers side is CW.

F. Reinstall top half of actuator case.  

G. Reinstall perimeter torx screws.  Do not over-torque them, just snug them up firmly.

H. Reattach cable "L" bracket. This can be done via drilling/tapping the remaining rivet shank and installing small screws/washers (we use #6-32 screws with flat washers and loctite). Or you can spot weld the bracket back onto the rivet shank.  Some others have used #8-32 screws as this provides a slightly larger tap.  Please do not use cheap taps here, the rivet is high strength steel so a high quality tap is recommended.  If you own a 4 door, you will be doing this 4 times so invest in a good tap to prevent breaking the tap in the rivet.  Tap SLOW using back/forth method until the threads are sufficiently deep, 1/4-1/2" is plenty.  Use loctite on the small screws to prevent the L Bracket from becoming dislodged later.  As a final suggestion on this step - some have just drilled a shallow hole into the rivet shank and used a self tapping metal screw to bite into the hole.  This works as well, and saves you the trouble of tapping a hole into the rivet shank.

*** After the install ***

Please do not reinstall the interior door panel until you have successfully operated the mechanism several dozen times to ensure all was put back together correctly.  We recommend installing the repaired actuator, lowering the window, then closing the door.  Verify both the interior and exterior door release handles function properly.  Then, start the engine, and ensure the vehicle recognizes the door is shut (doesn’t keep the dome light on, or chiming). Operate the power locks a dozen or so times, the lock should lock and unlock rapidly with a forceful "snap" as it moves (the way it did when it was new).  Only then should you finalize installation by reinstalling the door panel.

  1. Quality parts 5 Star Review

    Posted by on 23rd Sep 2018

    Chevy, Ford, GMC, Dodge, all the manufactures only care about profit, and use inferior parts any place they can. Thankfully, aftermarket places like Gruvenparts offer replacement parts that stand up to the test of time. Around 30 dollars, and 45 mins of my time fixed my problem. The dealership would have cost me somewhere north of 300 dollars to fix the same problem, and they would have used the same junk parts that failed to begin with. I have now freplaced the motor for the lock actuators on all four doors. None of the motors from gruvenparts have failed, and some are several years old. That’s a far cry from the manufacturer, which may fail anytime after 6 months.

  2. install hint 5 Star Review

    Posted by on 10th Sep 2018

    I found that a drill press helped a lot drilling out the rivet heads. Keep the case closed up during drilling. When I started tapping the hole with a 8-32 tap, I had to open the case to hold the rivet from turning with a small vise grip. Used 1/4 inch socket head bolts with washers to put the case back together. The new motor is very fast and strong. The old motors would fail if any of the manual lock linkage was binding.

  3. Awesome fix for door lock 5 Star Review

    Posted by on 18th Aug 2018

    I have been driving my 2009 Silverado for over a year with an faulty drivers door lock. Was dreading the 175.00 I paid to replace the passenger side a couple years ago. I stumbled on the you tube for this fix. less that 50.00 and a hour of my time I now have a functioning lock. You can even hear the difference in the motor operating in both doors. Great product,Thanks for saving me a around 150.00..

  4. Gm Door Lock Actuator Repair Kit is Awesome 5 Star Review

    Posted by on 5th Aug 2018

    I installed the motors in about 1 hour per door, they work flawlessly.

    Very Happy

    Thank you for a fine product.


  5. Great product 5 Star Review

    Posted by on 27th Jul 2018

    These motors are working great. I am glad that I found them instead of replacing the whole door lock mechanism.

  6. Door locks operating like new again 4 Star Review

    Posted by on 24th Jul 2018

    Door locks are working like new again. Replaced both front and rear passenger actuator motors. Great video on YouTube was super helpful. Replaced both motors for about half the price of one actuator. Job took a couple hours but well worth it. Would give 5 stars but motors seem a little pricey for what they are but certainly better than the alternative.

  7. This is the way to go! 5 Star Review

    Posted by on 24th Jul 2018

    Bought the motor with gear pre-installed, everything went pretty smooth and lock pops nice and quick now. The actuator i rebuilt was an aftermarket that only lasted 2 years, either buy the motor and rebuild it yourself or buy Gruvens actuator thats already done, dont waste your time with cheap aftermarket parts. If you dont have fabrication experience just buy the whole actuator and it will be a painless swap, the rebuild requires more tools but its not too bad, the video on the website shows you how its done.

  8. Great replacement over replacing whole latch assembly 5 Star Review

    Posted by on 8th Jul 2018

    Great way to make the repair for less than half of the cost of replacing the whole latch assembly from GM. Just did drivers side back door on suburban with one of these motors and the passenger side started acting up not even a week later. I have since replaced it also, only regret was not purchasing both sides at the same time to save on shipping.

    Time will tell how much longer these motors last versus the GM ones.

    I was unable to follow the install instructions fully. I was unable to drill through the rivets on either door latch even with a brand new milwaukee brand drill bit. I ground the heads down far enough to pop the L bracket off, did the motor swap then reinstalled the L bracket by putting a spot weld on top of the existing rivet head to hold the bracket down.

  9. Best Option 5 Star Review

    Posted by on 8th Jul 2018

    I was very happy with the results.Changing the motor was a breeze.Best option for this repair. Saved money,well worth the effort. Installation Video was A+

  10. GM Door Actuator Motor 5 Star Review

    Posted by on 7th Jun 2018

    I just ordered the passenger side first to make sure I could do the job. Turned out great! Much cheaper than the 'Stealer' wanted. I just ordered the driver side today
