*** PLEASE NOTE : THE IMPROVED 2014+ GM ACTUATOR MOTORS ARE COMING SOON !!! *** (email paul@GruvenParts.com for details).  If you have a 2014+ model, please contact us before ordering this motor so we can be certain to send you the correct motor !!

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 positon (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 perimiter 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 sufficicently 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. They work great 5 Star Review

    Posted by on 9th Dec 2017

    The motors work great, it's just a pain to get the lock mechanism open and reclosed

  2. Perfect Part- Great Product 5 Star Review

    Posted by on 10th Nov 2017

    This part does exactly what GruvenParts said it would, follow their online video and if you’ve done repairs like this before you’ll have no problems doing this one. Did passenger door first, took about 2 hours, most of that was disassembly to get to the lock and then reassembly to put it back in… the actual replacement of the motor was a little under an hour. As most everyone say’s use good drill bits and taps as you don’t want to break one off in the rivets. Drivers door took just over 2 hours, not a bad day’s work for the return on investment. Another GREAT PRODUCT from our friends at GruvenParts.

  3. Works great 5 Star Review

    Posted by on 5th Nov 2017

    On the driver's front door there's an extra rod for the key.

    Buy a tap and matching drill bit, don't rely on self-tapping screws. 6-32 screws fit within the rivet shank diameter well.

    The rivets go all the way through the assembly, don't be afraid to drill half an inch to match the length of your screws.

    Thanks Jim for the review. We have had good success with the tapping screws for "field repairs" however tapping is great too. Just go very slow and DONT break the tap off in the hole. Use a very good quality tap.

  4. Glad I did it 5 Star Review

    Posted by on 3rd Nov 2017

    I was a little hesitant at first , but I am so glad I bought these motors for my actuator locks. It was not as bad as I thought to replace them and not only did they work great but I save a lot of money.

  5. Wish I had done this earlier 5 Star Review

    Posted by on 27th Oct 2017

    My drivers door stopped locking/unlocking and I bought a aftermarket replacement latch assembly for $85, it failed in 2 months. I found your web site, ordered a new motor with gear installed, installed it myself which was super easy thanks to your video and now all works like new. Thankfully I had not thrown away my factory original assembly yet because the aftermarket unit was from china and was very cheaply made. I took them both apart just for kicks and the factory unit was vastly superior. I used the factory unit to repair.

  6. WORKS GREAT 5 Star Review

    Posted by on 24th Oct 2017

    I saved a lot of money buying these motors and they worked perfect.

  7. Outstanding parts 5 Star Review

    Posted by on 18th Oct 2017

    I replaced the lock actuator motor in my 09 Yukon Denali. In total, 45 min repair. I'm very confident this repair saved me $450 had I gone to the dealer. Now, with the Gruven Parts replacement, I am confident this motor will not go out again. Now, it will be a matter of time until the other 3 OEM motors need replacing. I highly recommend these motors, they drop right in very easy.

  8. 2009 Tahoe - So far, so good... 5 Star Review

    Posted by on 9th Oct 2017

    Dealer previously replaced one that didn't last as long as the other 3 originals. But... From GruvenParts.com, I ordered and installed new door lock, actuator motors on all four doors of my Tahoe. Followed the rebuild procedure from YouTube video. Works as described and working well. Not difficult to do. If you are a DIY'er, you'll be fine. Saved lots of $$$, too. Fast shipping! Thanks. Go Tigers!

  9. Cost Effective DIY Hack 5 Star Review

    Posted by on 5th Oct 2017

    I just installed the kit after dealing with failing OEM actuators for the last year. I wish I had found out about this kit sooner. With the video instructions given in the link, the job took less than an hour per door. With only a week into the new installation, I am very happy with the product. I'm hoping these hold up long term as promised.

    -- response --

    Thanks for the review ! hopefully its not a "hack" but more of a cost effective solution :) Let us know how the motors continue to perform, you have a lifetime warranty on them.

  10. So far so ggod. 4 Star Review

    Posted by on 2nd Oct 2017
