3rd row seat power fold motor fix?

[ReaperHWK]

2015 Tahoe LTZ.

3rd row power seat stopped working (the 40 of the 60/40). It was stuck down and I hear the motor working. Looked at the cables and everything looked intact, the motor wasn’t pulling the cables. Removed the seat and now it’s in the garage.


Looks like I need to remove the seat cover to get to the motor and see what’s going on. To me looks like the motor is not connected to the cables, either snapped cable or not connected.


Anyone replace the motor before? Can I even buy this part separately? I looked on YouTube no videos I can find of a motor replacement within the seat.

Any help would be appreciated before I blindly start taking the seat apart.

Watching this, keep us posted. I don't have any answers but definitely curious.

Messed with the seat a little. Was able to get the seat cover off and if you flip up the foam you will see the actuator that controls the release cables. The motor that actually moves the seat is behind the seat and uses a sprocket attached to the metal seat bracket to move the seat. It’s supposed to work by the cable actuator first pulling the cables to release the latch, then the motor moves the seat(there are actually 2 motors, one for moving the seat and one for releasing the cables). Tried to get pics of them both.


I’m going to hook this up to the car tomorrow and see which motor isn’t working. I believe the cable actuator motor is FUBAR and the seat motor is still good. I could see the motor trying to move and it would actually deflect the metal in the bracket.

That sprocket above actually should go into the black bracket but I had to separate them because I can’t move the seat open and close with the motor jammed in there.

Hello, my right seat is stuck in the almost upright position. I can hear it trying, but won’t budge. What part needs to be replaced.

#11 in the diagram. That releases the seat locks. If the locks release and it doesn’t work it’s the motor, #12

Hello. I i’m currently going through the same situation for 60 portion of the 3rd row seat. Its stuck in the down position and I could see and hear the motor trying to move but it’s not releasing. I also see both the cables slightly move, but no dice. Did you figure out exactly what was wrong with it and do you know the part number for that actuator that releases the seat? I did manage to pull on the black tabs that hold the 2 wires and the seat released about 5 inches with so now it’s stuck at an angle. Next I will be removing the rear storage box to get a better angle on those tabs so I can at least get the seat upright for now.

I had been experiencing intermittent problems with this seat, not wanting to go up or down, every so often in the past few years now it just don’t come back up.

Yeah I fixed this a long time ago. Number 11 in the diagram. Go to tasca parts website or some other online GM parts dealer and you can find that diagram and it will show you what PN to buy.

You need to remove the seat from the car, and remove the seat cover and foam. Then you will see the actuator and it will be fairly obvious how to replace it.

Since your motor is trying to move the seat id say your issue is the same as mine was. The seat release actuator is broken. That’s #11 in the diagram.

Do you know the part number for #11 I can’t find anything that looks like it on the tasca

I have an issue with the 60 side of my 2019 Suburban power rear seats. The pulley pulls the cable to unlock/unlatch the seat, but one of the plastic arms that holds the cable is broken. It looks like the whole seat frame might need to be purchased but I’m hoping there’s another solution.

I was able to move the latch with a screwdriver to lower the seat.

That latch only releases the lock. If I were you I’d try to fix it with a zip tie or something. It may work.

I might have to try that as I can’t find a part number for the plastic arm. I think the whole seat frame has to be replaced for that one part.

If anyone else has figured out what works best, I’m all ears!

Hello, I have the exact same issue and behavior. The 60 portion of the 3rd row seat is stuck in the down position in my Chevrolet Tahoe 2016 too. I can see and hear the motor trying to move, and cables slightly moving. I have manually forced and lifted the back from down to 5-10 degrees angle by pulling the 2 black tabs. Forcing more the back seat I'm worried I'm going to damage something else considering now it's very hard and stuck the same way you are experiencing. I was able to remove completely the cover leather and foam. The back seat foam got broken during the removal process (I'm not happy about that but I will glue it back or buy a new one if I can find it cheap). Now I can see the actuator with cables. I took few pictures and now trying to figure out the part number. Any help with the part number and website where I can buy it?

Here is the picture of the actuator. Which one is the part number?

Suggest posting the last 8 of your VIN and asking @915_Tahoe for the current part number.

You could also take a look at this part, but I don't have an overall view of the part you're looking for or know if it would be for the correct side. Click the link and look at the part, then start that search over with your VIN and see if the part you're looking for is listed.

Did you read the thread? Post #2. F/n 11. TASCa parts or any other online retailer has them. All the online retailers have that diagram and will have the latest PN for your VIn.
