Has anyone figured out why these things are failing that soon? I am wondering if it is an alignment issue, lack of internal lubrication, or if they are just plain cheaply made.

After having replaced one of three failed ones my vote is "cheaply made", though alignment of the convoluted lock shaft could be part of it. I wonder if they've made any design changes, or are they happy for the repeat business?

I'll bet this is not considered a safety issue since you can still lock and unlock manually, therefore there wouldn't be a recall. Sure hope we're not looking at replacing these every 3-4 years. I've never had one go out any any other car I've owned in the last 30 years.

Right I have one out and my drivers door is not intermittent, Gm needs to do an recall or at least make the parts cheaper. We should make a letter and send this to gm....

Thanks for the great writeup

BBTKD,

I really appreciate the writeup. My passenger front door lock exhibited the same symptoms. I couldn't find an aftermarket part so I just shed out 184.87 at the dealership for the part that is not in stock.

When it arrives this week, I'll try to get back and let you know how the install goes.

Thanks again.

Already have had two fail - driver rear and passenger front. Bought both, replaced the driver rear first since it's a pain to reach - after that ordeal, hesitant toward tackling the passenger front until I have another surplus of ambition and free time.

Really tics me off failing so early. 'Made in Mexico' said it all. Wasn't happy to see all the plastic clips and what not involved with the assembly.

Paid $166 for one and $176 for the other - not sure which was which.

Love the car as a whole, but hate the reliability of some pieces-parts. So far - two power door lock assemblies, one power mirror switch, and one evaporative purge solenoid. Begs the question of what rate of failure will be experienced down the road?

2008 LTZ - 205,000 miles
1981 CJ-5 - 171,000 miles
1989 F150 - 217,000 miles - SOLD
2014 F150 - too new to rate

Common Problem

Thanks for the info bbtkd. I have the same problem. Right rear door actuator went out at 30,000 miles, repaired under warranty. Now the left rear has gone out at 40,000 miles. No longer under warranty, so I will attempt to fix it myself. Having serious reservations about GM products. Also had electrical problems with 2001 Impala.

I just picked up the actuator for the left rear and will be installing it in two weeks when my daughter is home. Then I'll do the right front later.

Thanks for the help!

I'm new to the forum and found it by searching for door lock actuator replacement. I just wanted to thank bbtkd for the detailed instructions on how to replace. It was a great help. I do appreciate it very much! Saved me some $$$

Wow dont pay that. You can get a universal set of 2 for around 25-40 bucks depending on brand. And those are really reliable.

Dont replace a faulty design with a faulty design. I'm having to fix this on my moms. The rear door handles are also not working.

I used the GM actuator. Very pricey but the lock is and the cable for the inside handle is mounted to it and I couldn't figure out how to mount a universal. You might want to go to a GM dealer and look at one before you try the universal.
