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.
- Send Us Your Actuator for us to Repair : Send your actuator along with copy of your invoice (address will be provided after order). 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.

2008 Sierra door locks like new again!
Posted by G L Miller 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!

easy repair
Posted by Terry 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,

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.

Auto Lock Replacement Motor
Posted by Chuck 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.

08 Suburban door locks
Posted by R. Cramer 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.

Great replacement for a fraction of the cost.

Take your time when drilling out rivets, use a dab of oil every so often for drill bit. I broke a few drill bits trying to rush the process. Great product and fast shipping.

Works as advertised
Posted by Unknown on 21st May 2017
I got the motor only for the door lock actuator and followed the video and it worked OK. What previous people said about minor flaws in the video are true. Next time I think I will spend the extra money and get the unit already fixed/assembled and send my core back. There are a lot of things that could possibly go wrong taking the actuator apart and installing the motor. Also, if I got the assembly, I would have been done in half the time. I think it took me about 4 hours to do this one, but it would probably speed up on subsequent ones.
-- response --
OK thanks for honest review here. Once you do a few of these, it literally takes 15 minutes.
*** One thing I keep mentioning to people who call or email - PLEASE set the latch in the shut/closed position before disassembly/reassembly of the halves !!! This moves the internal bits away from the perimeter of the case and makes things a WHOLE LOT EASIER when reassembling. Ive had alot of people disturb the internal bits when reassembling the case halves. By closing the latch as if door were shut, it becomes much easier.
Also, bench test the unit before buttoning up the entire door skin. Plug it, start car, make sure car computer knows the door is closed, operate lock unlock 10 times, ect ...
Alot of people seem to install, button up door panel, put tools away, then send wife out to grocery store before testing what they have done. There is lots to go wrong if this is your 1st repair on the actuator, so go ahead and test it by plugging into the harness and manually latching shut then open, lock then unlock. Ensure dome light goes off, chime stops, door ajar light on dash goes off, ect ... Test it before bothering to install/button up door skins.
