Thank you for your videos. By watching all 3 videos, I was able to open my trunk and change out the lock actuator on my 2004 Trailblazer and I am a girl! Thank you again!
Perfect video!!! Outstanding! I was going around in circles trying to figure out my back hatch and figuring if it was the lock actuator or the body module. Figured I try this first and your video helped me remove the actuator! Actually had it off in 5 mins. Added the new actuator and now my hatch is back functional! Thank you!!
Glad it helped! That is a bit tough to figure out but a piece of cake to fix. The hard part for me was finding that little hatch that unlocks the door.
thank you for a great instructional video that is so helpful, i chose to go to the junk yard a get a couple of these from lower milage trailblazers, this video helped so very much and saved me a ton of money..thanks again
I am going to replace my 2007 trail blazer lock. I bought a used trail blazer but I love it. It runs very good, now I am definitely going to work on the lock. I bought it from Amazon.
I just changed out this part successfully, thanks to your concise tutorial. Thanks so much! - Now I have to figure out why the key won't open the drivers door???? All fuses checked out fine.
Your video was soo helpful. I went to my local u pull it and paid $23. Problem solved. Thanks. A little tip, use a needle nose plier to push the metal through the plastic clips. Disassemble should take no longer than 5 min or less.
Ordered same part number not doorman off amazon $24....and it works! Plus it came with a new yellow clips for the top rod which mine was almost broken so worked out well for me.
Thanks for the video finally got it fixed it was bothering me for 2 months, I went to my junk yard to take a chance on it I got it for 18 dollars instead of 263.99 at a auto parts store or eBay
Alright DMurph, I am going to do this today with the guidance of your video on my 04 Trailblazer. Local Muffler Man wanted 500 dollars to do this job! I was like, "skip that," I gotta figure out how to do this in my garage.
I hope the job goes well! $500 is ridiculous as this job is pretty easy. Also check out my trim panel removal video to find out how to get to the actuator and please let me know if you have any questions! The actuator activated as soon as I plugged it in so it may be helpful to disconnect the battery.
@@savorwithdmurph1113 Job went smoothly. The hardest part was lining things up with the new part. I am glad you mentioned don't mess with that white piece on the actuator. I also didn't plug in the power connectors until the end. Good video. I wasn't experiencing the noise you were hearing but in the winter time on the coldest days, the door wouldn't shut. I would park the trailblazer in the garage and would eventually shut. Then the last straw was the back door wasn't locking keeping people from getting in.
Dang! Yes it sounds like it was time to replace the actuator Gregory. I'm glad my video helped out! I noticed there aren't many videos or even pictures of how to do this job and wanted to make something helpful. My door is doing well a month or so out and I"m glad the crazy noise is gone haha! Near the end, my door would lock but not unlock it was a real pain. I had to climb in and manually unlock it lol! Now it works good as new =)
I'm glad this video helped out Chicken Does! I did quite a bit of searching myself and couldn't find a decent tutorial online. There are a few videos that give you an idea of what the job will take. My goal was to make a video that has everything you need to get the job done. The part was hard to find as well...
I need to do this, but my problem is that I can't even get teh hatch opened at all, not even from the little hole in the back panel. So I'm in the process of just breaking apart the current mechanism, being careful not to damage any parts I need to reuse. 07 GMC Envoy
Remove the back panel. Had the same issue with my 2002 trailblazer and my brother took that big plastic piece off( was mentioned at the end of this video) and than he used a screwdriver to pop the hatch open but that will only work for so long. You will have to replace the actuator.
I ordered and installed the same part off Amazon for $50 instead of $150 and it works just fine. Just a financial heads up. The more expensive one may have a warranty or some other reason for being expensive but the $50 dollar one works.
Good to know! Feel free to post a link to the part for other viewers. I bought a $50 distributor cap for one of my cars a while back and it didn’t do a thing (after hours of labor) so I started going with the higher priced, brand reputable items for electronics etc.
Nice vid. I have to do this and rear drivers side door 🙄😏. One of the torx screws is stripped. So i guess its a hex screw now. It feels good doing it yourself..but its always something on the 02-09 GM suvs.
Thanks... did my 2004 Rainier today - part was $82. ... I pushed those arms up through the plastic BEFORE I took the bolts out, just needed a flat head screwdriver and "pop" up they went. Otherwise, followed your instructions as presented.
Nice install of the liftgate Lock Actuator but, what if the handle on the outside latch piece of the lift gate is also broken which doesn't allow you to open the liftgate as well. Could you maybe provide video replacement parts needed and a video on how to repair that latch part of the liftgate mechanism?
mine worked great one day then the next i cannot open the hatch or the back window , both happened same time , i hear the lock mechanism working when io hit the lock on the car f.o.b but wont open and the glass button pushes in but i do not her that one click .
what was the noise that you were getting, mine keep trying to lock when the gate is lifted. Also, how did you get the reverse lights not to come when you unlock the trailblazer with the remote control?
Time 9:43 when you’re reattaching the metal poles one on the left red to red one on the right green to red where does the green connection go when it goes up On my 99 jimmy there is no metal pole connected to the right red connection can you help please
Got a buffet i bought in the back of my car and it won’t open so I can’t get to anything to remove the part or the buffet which takes up the entire back rows. Any other ideas?
Yeah, it was only engaging one way. If it's working both ways that would be a proactive repair. Nothing wrong with those. I've replaced several components before they failed.
I have a Ebay replacement actuator... connected the 2 plugs (not mounted... just checking electrical)... my fob is not causing any action. Does the replacement actuator need to "programed/coded" to my fob?
So sorry Dan. I also have several air conditioning actuator videos that get commented on quite frequently and I thought this was one of them. It does not need to be programmed or coded. It is a plug and play. Do you have a link to the part?
@@savorwithdmurph1113 Thank you. Yes, this is in regards the rear hatch actuator... not (a) heating or air-conditioning matter. There are 2 plugs (one has a two leads and the other four). The 2 lead plug (truck wiring harness) I was able to use a voltage tester... hit the fob button... showed "hot" on the meter) the holes in the 4 lead plug was too small to accept the leads on my meter. I contacted ebay and told them I believe the (used) actuator was faulty.
The gate ajar light? Find where it gets pressed to turn off and test that. It looks like this is located near the lock. If that works properly, it may require readjustment so it is triggered when the back latch closes. It sounds like something may have been moved during the repair. Also, I used the oem part and there are some low cost alternatives that may not work properly. Is the part locking and unlocking? There are a few threads on google that discuss this as well. This is a good start. www.fixya.com/cars/t7440257-gate_ajar_light_eventhough_back
Yes the trunk ajar light is on. I have a 08 trailblazer. It locks and unlocks. Im almost certain I adjusted something wrong. But I went to a salvage yard and pulled the part off myself. Where are these threads located?
Do a google search 2008 trailblazer gate ajar light stays on and it'll bring up quite a few results to look through. You'll want info that's closer to your year of make just in case there are any differences in years.
@@savorwithdmurph1113 yes. I even try replacing the remote. I was at work when it stop working. And i notice that the tail gate stop working at the same time. It only works manually. So i tied a string to it to open it
Your doing way to much release 2 wire pigtails first then the red and green "swing clips" then remove outside torque screws then inside torque screws install is reverse of removal
Totally did this backwards. First undo the wire harnesses. Next undo the metal rods while there is nothing lose. Next remove the two little screws. Next remove the three main retaining bolts on the exterior. To install do reverse order.
I was able to replace mine in my 06 trailblazer in about ten minutes after watching this video. Thanks.

Thank you for this video. I ordered the actuator from amazon for $50 and will install when it arrives. Your video is quite helpful.
Just got my actuator for under $50. After watching your video and gathering the proper tools tool maybe 20 minutes to get it done.
This video, and the one showing the trim panel removal, helped me greatly. Thank you!
Glad it helped! I actually added the trim panel removal video to complement this one.
thank you for a great instructional video that is so helpful, i chose to go to the junk yard a get a couple of these from lower milage trailblazers, this video helped so very much and saved me a ton of money..thanks again
Excellent! Yeah I bought mine OEM new and it was a bit pricey. Great idea to grab some low mileage junkyard ones to save on cost.

I appreciate the specifics of the video that you offered. Thanks man.
Many thanks! Changed my rear hatch latch like a boss. 👍👍👍
Haha! That's why I make these videos =) To make you guys look really cool and save you a buck or two as well. Glad it helped!

I sold my trailblazer but I'm sure there is videos/details out there. I'm imagining removing that internal panel will provide access.
Question
Did it show rear access door open on the cluster panel. I having this issue all my doors open except for the rear tailgate and glass
Ecxelente video, saludos desde Maracaibo Venezuela.
mine worked great one day then the next i cannot open the hatch or the back window , both happened same time , i hear the lock mechanism working when io hit the lock on the car f.o.b but wont open and the glass button pushes in but i do not her that one click .
Thank you... you're a good man
Thank you Dan! I appreciate the view and comment! I try to make your lives a bit easier with these repair videos.
Very helpful, thanks!
Great video, were you able to use your old key frobe/remote or did you have to change it?
My key fob kept working after I changed the part.
Thanks, well done
Thank you George! I'm glad this video helped out.
what was the noise that you were getting, mine keep trying to lock when the gate is lifted. Also, how did you get the reverse lights not to come when you unlock the trailblazer with the remote control?
Time 9:43 when you’re reattaching the metal poles one on the left red to red one on the right green to red where does the green connection go when it goes up On my 99 jimmy there is no metal pole connected to the right red connection can you help please
great thanks alot very helpful
Thank you
Got a buffet i bought in the back of my car and it won’t open so I can’t get to anything to remove the part or the buffet which takes up the entire back rows. Any other ideas?
My open door lights won't turn off now. Finished the installation of the actuator but no luck gettimg the lights off. Any suggestions boys?
How did you test this to see if it's bad?
And not the control module
Thanks! job done with the normal mental delays :) on my 2004 Trailblazer.
Autozone wanted $224.00 !
found it on carparts.com for $36.00... booya!
Haha awesome! I understand those delays... lol! Glad you found a good price.
How do you remove it if you can't open the gate?
There is a lever on the inside of the gate near the bottom. You remove a small circular cover and then move the lever to unlock it.
Did your keyless entry remote stoped working when the module messed up?
All the doors still lock except the hatch
Did you replace actuator after the liftgate would not open ? When i lock or unlock doors with remote you can hear the actuator engage
Yeah, it was only engaging one way. If it's working both ways that would be a proactive repair. Nothing wrong with those. I've replaced several components before they failed.
I have a Ebay replacement actuator... connected the 2 plugs (not mounted... just checking electrical)... my fob is not causing any action. Does the replacement actuator need to "programed/coded" to my fob?
Did you reset your HVAC system while the actuator was plugged in?
Actuators are not plug n play. They require a system reset to calibrate.
@@savorwithdmurph1113 .... I missed that in your tutorial. How is this "reset" of "HVAC" achieved?
So sorry Dan. I also have several air conditioning actuator videos that get commented on quite frequently and I thought this was one of them. It does not need to be programmed or coded. It is a plug and play. Do you have a link to the part?

My car key remote and gate not working
Thanks for the video, but damn 150 bucks, do you ever check eBay ??? Same damn thing for 30 bucks.
Did your remote stop working when it messed up?
It still worked. Did yours stop?
Yes it did
Did you try replacing the batteries in the remote?
@@savorwithdmurph1113 yes. I even try replacing the remote. I was at work when it stop working. And i notice that the tail gate stop working at the same time. It only works manually. So i tied a string to it to open it
Your doing way to much release 2 wire pigtails first then the red and green "swing clips" then remove outside torque screws then inside torque screws install is reverse of removal
Yes, very true. Unfortunately I learned that after making the video.
make your life easier with a red impact
Totally did this backwards. First undo the wire harnesses. Next undo the metal rods while there is nothing lose. Next remove the two little screws. Next remove the three main retaining bolts on the exterior. To install do reverse order.
So you saw that? Haha yes, I did it the hard way and found out afterwards. Great catch!
