2009 Yukon XL Denali - Rear Drivers Door Won’t Open

[KraftMatic87]

I finally got this resolved. I was able to get the Dorman lock actuator to work. The issue was that the rod that connects the outside door handle to the actuator was rubbing against the inside of the door, keeping the actuator from re-engaging the lock latch once the door closed. I was able to bend the rod slightly so that the tip was pointing towards the inside of the vehicle, allowing the rod to move up and down freely and not get stuck in the open position.

I’m at least thankful GM made these door panels so easy to remove, even when they are stuck closed! Glad this problem is finally put to rest.

Nice Video Pete! I've done this multiple times now. Not used the torch but have had to retrieve my built in nuts and JB Weld them back into place.

This is also a very good testament to how cheap and brittle the grade plastic used is... That torch isnt on there but a few seconds yet the plasti-chrome is near liquid form.


**Another repair I've made a couple times, and made it a little better each time is to the area INSIDE this spring.

There's a cross pin that runs through the center of the whole spring/latch release apparatus here Ive highlighted with 2 Yellowish Orangeish Gold arrows. There's a LOT of forces being enacted right here and its far enough from the two anchor points that, if they're loose at all, it can allow enough flexion to cause the spring to rotate out of position, to not do it's job properly...

What I did was cut a small piece of tubing to go in the void space: Inside the coils of the spring and Around the shiny center shaft pin.
The pin with the two YellOrangGoldish arrows.

So you're inserting a piece of stout rubber or plastic hose, that is just barely longer than the coil spring, long enough to fit the space(maybe .70" IIRC?) that is just barely smaller than I.D. of spring coils....... and has an I.D. of it's own that is just larger than O.D. of center shaft pin...

Said actions drastically reduce the rotational ability of the spring/release apparatus.....loose anchors or not

Hope I explain that in an understandable manner?
