Front Left Driver Side Door Lock Actuator Motor Assembly 931-303 25876382 | For 2007-2010 Chevy Silverado Sierra 1500 2500 3500 HD, Tahoe, Suburban, Yukon, Avalanche, Escalade Replaces 20783846

Bought this to replace a failing door lock actuator on my Sierra. However I noticed that some pins are missing from the module. The problem is the passenger side door sensing must go thru the missing pins. Now my truck will not lock automatically and displays the passenger door is open. Update Miraculously the passenger door open message went away and the automatic door lock works. Will monitor. Works as expected

On my wife’s 2008 Silverado she locked it one night and the next morning the alarm was going off. This happened several times in the next two hours and there was no horn chirp when you locked the truck with the fob. The interior light also quit working when you opened the door and when locked there was a car and lock icon showing on the instrument panel. When cranked and put in reverse the driver door open message appeared. This item fixed all the issues. It’s a little tricky to install but there are several YouTube videos and I recommend watching several before attempting this repair. One video and the only one that gave this tip was to remove the bottom bolt of the window regulator and bump the regulator back to give you room to work was really helpful.

Fit perfectly. Has worked fine for several months. Saves a lot of money over local suppliers.

great product!

Less than two months after purchase this actuator has started to fail. The latch assembly does not catch the latch pin if the door is pulled/pushed closed with a minimal amount of force. The door will bounce off the latch pin as if the mechanism is hanging up and won't engage around the latch pin. Originally I thought this was an alignment issue but after spending a couple hours trying to adjust the actuator, latch pin and all the actuation rods nothing improved. If the door is placed against the latch pin and lightly pushed it will engage and lock, most of the time. On one occassion the actuator appeared to latch and even locked but upon turning a corner the door swung open. A couple different attempts have been made to contact the supplier and no response has been received. Hopefully I just got a bad actuator and this isn't a common issue for others.

Find yourself a youtube video. If you're handy and have the right tools ready to go, it's a 30 minute process at most. I did it in about 30 minutes including having to remove the door panel twice because the first time I forgot to reconnect one of the harnesses and it fell behind the door. Tools needed: 10mm socket with long extender Torx bit (I think its a T25, fairly big) small flat screwdriver plastic pry-bar (I used a bicycle tire remover). flashlight (yes, even during the day) Door panel comes off with 3 10mm bolts hidden behind plastic covers, several plastic pop clips around the sides and bottom, and then lift it up off the door to remove. Pop out the switch panel and remove connectors, disconnect wire pull attached to door handle. The actuator is attached at 6 points: Torx bolts to door, 3 metal rods, the pull cable and the wiring harness. -Drop a flashlight into the bottom of the door so you can see better. -Take a picture of the actuator in the door so if you get lost, you can remember how everything is attached. -My suggestion after doing this is to first disconnect the rod attached to the yellow clip (hint, the clip opens by pushing the tab towards the OUTSIDE of the car). -Then unclip the rod attached to the key. Don't try to unhook it from the actuator. It is connected to a red plastic clip up at the top and can be removed by pushing the rod towards the BACK of the car. -Remove the torx bits. -Now you can move the actuator around within the door to unclip the pull cable and the wiring harness. The wiring harness is released by sliding the red plastic tab up. 2 rods will still be attached to the actuator, the key lock rod and the one going up to the lock indicator. Remove all from the door. To reinstall: -Attach the key lock rod and lock indicator rod to the new actuator -Slip the lock indicator rod up into its position in the door and attach the key lock rod back to the red clip. -Attach the wiring harness and cable pull -Bolt the actuator to the door with the torx bolts -Attach the door handle rod to the yellow clip -Reattach door panel with all wiring harnesses and the cable pull

I am generally against buying knockoff parts like this. But considering I couldn't source the factory GM unit for less than $200 at the time, I figured it was fiscally-irresponsible not to give this a try. If it lasts a year then it was worth the price. That said, it functions like it should and is pretty close to factory fit and form. No problems with install and worked out of the box. So far I do not regret the purchase.

So far works great! Fixed dome light not coming on actuator works great too for door lock

El producto se ve de buena calidad y quedó perfecto, el único detalle es el conector era diferente al original aún y cuando decía que era compatible, afortunadamente pude arreglarlo para conectarlo.

The part was lost on delivery but mysteriously delivered 24hrs later. Perfect fit for my use.

Worked great about 1/2 hour install, cheaper than dealers price , look on you tube for directions

Simple replacement part. Works fine.

Reste barré. J'ai eu beaucoup de problème à ouvrir la porte qui était resté barré.
