*** 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. Excellent customer service 5 Star Review

    Posted by on 25th Mar 2017

    Saw video on how to fix locks on my truck so I took a chance and ordered two for the drivers side to try. Did both and decided to order passenger side ones. Only received one in the mail, so sent email right away and explained the situation. They said one would be sent out next morning. Now I have both and fixed all my doors and they work better than ever before. I would recommend them to anyone that have problems with their door locks.


  2. Easy repair 5 Star Review

    Posted by on 14th Mar 2017

    Take your time and use good self tapping screws not cheap ones they can break. Works great.


  3. I SAVED at least $100 dollars 5 Star Review

    Posted by on 9th Mar 2017

    Both the actuators in my '08 GMC Sierra were out, and they are not cheap to replace. I ordered the two repair motors from Gruvenparts and they were promptly delivered. I carefully reviewed the detailed and nicely done YouTube video on how to complete the repair, and I got the job done. My power door locks work better than ever, and I couldn't be happier. I am NOT a highly skilled mechanic, but with patience and the basic tools, this a repair that can be done at home.


  4. Easy Installation 5 Star Review

    Posted by on 1st Mar 2017

    I have 3 bad motors in my truck. I bought 1 to try, the hardest part of the installation is drilling out the rivets. Once I found a sharp drill bit the rest of the installation was very simple. it took me about 45 minutes to do it. it works perfectly. I will be ordering 2 more for the rear doors. the video was very helpful. thank you. I would highly recommend.


  5. Works as advertised 5 Star Review

    Posted by on 26th Feb 2017

    I installed 3 on my '09 Sierra Crew Cab. No problems. Saved hundreds over new actuators. After grinding the head off the rivet with a Dremel, I drilled the rivet with a 1/8 drill and used self-tapping screws to re-install the L-bracket.
    Get yourself a couple of good drill bits. Watch the video first.


  6. GMC door lock repair 5 Star Review

    Posted by on 22nd Feb 2017

    I changed the door lock motor as described in the video. This gave me the excuse to putter around in the garage and get away from the old girl for awhile. It went smoothly and had the added bonus of saving $300.00. Everything is working great so far....... I wanted to purchase a North American car. When I took the door lock apart I noticed the motor inside was made in China. No wonder all my door locks were screwing up. This is a great way to save money and recycle a part rather than throwing it away


  7. Easy fix 5 Star Review

    Posted by on 20th Feb 2017

    Replaced my 2008 Silverado passenger door lock motor with Gruven parts motor. No issues, works great. Disassembly was way harder than in video. Took about two hours to get it apart, but went back together in a 1/2 hour. I don't think I could have done it without problems without the video. Very good deal. Thankyou!


  8. Great experience 5 Star Review

    Posted by on 18th Jan 2017

    I ordered the motor with the gear pre-installed. It was shipped quickly, arrived on time, and was the right part. The motor fit exactly how it should, and the video was very helpful. Will be using this site again if (when) the other motors go out.


  9. Easy Fix 5 Star Review

    Posted by on 17th Jan 2017

    Manually closing the passenger door was driving me crazy. This is an awesome way to fix the door lock mechanism. The instructional video helps a lot. The parts looks great . Very easy to install.
    Thank you


  10. Door Locks Work Again! 5 Star Review

    Posted by on 8th Jan 2017

    This half a million Mile '08 Suburban has gone through many actuators and finally got to the point where I just manually locked the truck. 2 weeks in on the new motors and I can tell you that these are much stronger than stock or even Dorman replacements. The installation video is crucial and the most difficult part was threading the old rivets with self tapping screws upon reassembly. I paid for 3 motors at the cost of one full lock assembly.
