Door Actuator Part #

B-Dawg · January 28, 2011

I have a 2008 CC Silverado with 37,500 miles. So it's out of warranty. I need a left rear door actuator for the door lock. Anyone have the part # and best place for one?

I need the last 8 of the VIN to help me look up the proper one,there are a few different ones.

Also I'm betting with only 37,500 miles they would do a "goodwill" repair if you bought it from them.

I brought it in this morning and they informed me about the warranty. I don't hardly ever look at the miles I didn't even think about looking to see if it was over. Anyway 8G298365

and THANKS.

I just had my replaced for free on my 2008 with 54,000. I called GM and told them about the lock issues. They gave me a service number and said to take it to the dealership. The dealership replace my front 2 actuators completely free and called it a "goodwill repair". Try this route before you spend you hard earned cash!!

I agree, I work at a dealer and we routinly will goodwill stuff. Especially if its a well known issue like the door lock actuators. We just did one on a 08 impala with 74k miles on it.

I have a 2008 Silverado 3500 last 8 Vin 8F202814.

$141.67 - Driver Front – 2587-6382

$132.17 - Driver Rear – 2587-6383

$154.55 - Passenger Front – 2587-6397

This is what I was quoted for the door actuators. How frustrating that GM didn't stand behind this problem. There are so many of us with this issue. I was offered 15% off at the dealership. I love my truck and this isn't the end of the world. Just thought I would share the part numbers

I replaced all there yesterday. I watched a video on how to remove the door panel. It was very helpful.

When installing the driver front left actuator, it was very difficult to get the metal rod that attaches to the exterior key.

I has to rotate the actuator horizontal and with both hands insert the rod into the hole. Once in, I then rotated the actuator 90 degrees to secure the rod. This process was very difficult to do especially since I didn't know the process.

I also thought the new part wasn't working since I couldn't get the door to lock after I installed it. In my haste, I forgot the truck will not lock the driver door when open. Only with the door closed will the lock work. Don't make the same mistake. I took the actuator out a second time thinking the part was bad. My mistake, oops.

The only tools I used were a small screwdriver, 10 mm socket with extension, T-30 torques. The process wasn't that bad once I figures out how to do it. Definitely worth the time. If you are mechanically inclined. The there doors with out the key lock were simple in comparison to the driver door.
