*** 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. lock motor 5 Star Review

    Fixed my problem of electric door lock not working and works great! Easy to install with proper tools and following video.

  2. EASY PEASY 5 Star Review

    Posted by on 21st Jun 2017

    Just replaced all 4 on my 2010 GMC Sierra. Good instruction. The motor marked cw is for both drivers door and door behind driver. Ccw for both other doors. The driver's door has an extra plastic mechanism which comes off and goes on(easy) and the door key lock rod snaps out and in at key holder inside door. Otherwise, take your time, try not to break any of the plastic clips for door panels. If so, buy new ones(extras)to replace the broken ones. One last item, the bolt clips in the door for the door panel screws(3) can slip out of place so set them before reinstalling the door panel. I will send in the 4 old motors for a cash rebate. Thxs again for the excellent instruction video.

    -- response from gruvenparts --

    Terry thanks for your review! you can toss the old motors, we do not need those, better yet send them to GM so they can see what there motors keep failing over and over again!

  3. Great fit 5 Star Review

    Posted by on 20th Jun 2017

    Fits perfect. I used a 8-32 thread.rather than the self tapping screw used in the video.

    -- response from gruvenparts --

    Nice work ! Yes an 8-32 tap is also a good way to do it, just go really slow if tapping a hole so you dont break off the tap

  5. Great Product - 1/4 the price! 5 Star Review

    Product arrived very quickly - instructional video was great for even the lower mechanically inclined. Took about an hour - works like new!

  6. 2008 Sierra door locks like new again! 5 Star Review

    Posted by on 13th Jun 2017

    Just finished replacing 3 motors in my door locks, the other one was replaced under warranty. The locks are like new again thanks to the actuators motors I purchased from Gruven Parts. These motors were exact match and were easy to change after watching the video on motor replacement. The guy on the video did an excellent job. The only thing I would add is the 10 mm metal clips that hold door panels on fell down so I put a put a piece of tape on them to hold them in place. Everything else was exactly like it was in the video. Thanks so much Gruven Parts......You Guys Rock!

  7. easy repair 5 Star Review

    Posted by on 11th Jun 2017

    I was able to repair both doors in about 3 hours, this includes pulling the latches from the truck. Watched the video first, then installed the motors. Fast, saved a lot of money. Thanks,

  8. Cadillac Escalade Door Locks Sorted! 5 Star Review

    Posted by on 5th Jun 2017

    Although it takes a little time to receive the motors from he other side of the pond, we decided to order all four.

    I've changed them all over and its resolved the problems at only 25% of the cost.

  9. Auto Lock Replacement Motor 5 Star Review

    Posted by on 2nd Jun 2017

    I replaced the door lock actuator on my 08 GMC Sierra. I used the extremely helpful instructional video and the replacement went perfect. The interior of the lock assembly was a little different than the video but was relatively easy figure out. Everything else was exactly as the video showed. I drilled out the rivets and used a countersink to eliminate the rest of the rivet head. I tapped the hole with an 8-32 tap. The motor seems much stronger than the original equipment. I highly recommend gruvenparts.com. Shipping time was good and their emails kept me informed of the status.

  10. 08 Suburban door locks 5 Star Review

    Posted by on 29th May 2017

    Door locks would quit working when sitting in hot sun all day. Installed these motors and you can operate them 20 times and they don't fail. Watch the video and grind the rivets flush and use a center punch to mark the center of rivet to get the 1/8 " drill centered and the rest is a cake walk. Fixed all for the price of one complete actuator from local parts store. Wish you guys had these improved motors for the 99 suburban which I have replaced 3 times.
