** 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  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. Door lock is working again! 5 Star Review

    Posted by on 29th Jul 2019

    Replacement motor works great! This is the second motor I had to replace. GM didn't do well with the original motor.

  2. 2009 Cadillac CTS DOOR LOCK ACTUATOR REPAIR 5 Star Review

    Posted by on 12th Jul 2019

    I recently completed the installation of all four, door lock actuator motors on a 2009 Cadillac CTS. The installation was a complete success and all four doors are fully functional again. I highly recommend these motors. Be sure to watch the installation video.

    I chose to purchase just the motors without the brass gears pre-installed. Be aware that those gears are a very tight press fit on the original motors and tough to remove without damaging them.

    I used a drill press with a new drill bit designed for hard metal to drill the holes in the rivets followed by the thread tap method. I then ground off the rivet heads and removed the "L" brackets. Be aware that the tapping is a very slow and tedious process, but I managed to tap all eight rivets with a single tap.

    Reassembly was straight forward.

    This repair process is a great money saver for those willing and able to tackle the job. Thanks Gruven Parts for creating this option!

  3. Worked! 5 Star Review

    Just put in the new motor (with gear pre-installed) tonight...followed the YouTube video. Everything works perfectly now! :)

  4. Door Locks Work Great 5 Star Review

    Posted by on 29th May 2019

    I eventually had to replace the driver and passenger side door lock motors. The instruction videos were superb. The difficulty level is easy if you are a "do it yourselfer". Shipping was fast and everything came as expected.

  5. passenger side door lock motor 5 Star Review

    Posted by on 4th May 2019

    The new door lock motor works great. But now when I put the truck in gear I get chiming and a message that the passenger door is open. How do I fix this problem?

    -- Response from GruvenParts --
    It sounds like you dont have 1 of the internal components properly seated within the door lock ctuator. You will need to open it back up and position the internal components correctly, then seal it back up. Once you repeat this, please plug it into the wiring harness BEFORE reinstalling into the door, and verify the fault has been cleared. It may help to rotate the latch into the shut position, as that pulls away the internal components from the case perimeter, and makes it easier to put it back together without disturbing any of the internals. As always, call me or email me, we will guide you through it 100%.


  6. Great product 5 Star Review

    Posted by on 18th Feb 2019

    Wow, what a money saver this was! I had bought just the two left side motors and yes it is time consuming but if your handy with tools and not afraid to get your hands dirty this is a fun project. I lost 2 hours due to the brass gear went flying out of the garage and into the dirt, so if you're worried about losing the gear order the motor with it. I will tell my fellow truck owners about this.

  7. 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.

  8. 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.

  9. 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..
