Lock Actuator problem

2015 Suburban LTZ - 70,000 miles

 

Recently, the right rear door isn't unlocking on the first attempt with the power locks.  If I push unlock 5-10 times, it will finally unlock.  During those 5-10 times, the stem (Part you can see) is moving up/down slightly until it finally goes all the way up and stays.  No issues with locking.  The unlock with handle pull still works without a problem.  Is the actuator dying or is there a nut to tighten around the stem that may fix my problem?  I haven't opened the door panel to look yet, thought I'd collect ideas first.  I have a video but it's too large to post.

Pull open the door panel. :)

Guess I'll have to but thought I'd get the part (if needed) prior to opening it up.  I'll check youtube for how to access the panel.  I've done it on my old expedition so I'm guessing I can handle it.

I wouldn’t buy any parts yet. Might be as simple as the rod falling out of the plastic guide clips. Open it up and have a look. 
 

I used a video from A1 Auto on YouTube to remove my front door panel. It made the removal and réinstallation a breeze.

Will do! Thanks!

Most likely the drivers door switch, but also check to see if it unlocks while you have the drivers door open . Open and close the door as you hit the switch, if this has some effect, then it could a short in the wiring at the pivot point.

Well, I opened the panel and toggled the switch.  Definitely something internal as the plastic disc that turns up with the rod attached still wiggles but won't fully rotate without multiple attempts.  Local dealer quoted $425 to replace it :0  Guess I'll order the part for $100 and attempt the replacement myself.  Thanks for the replies.

      Mangoal or FitcamX OEM Dashcam?

      Late reply, but yes—it works on the SLT trim. Compatibility comes down to the plastic shroud shape behind your mirror, not the trim badge itself. On the SLT with auto-dimming, it uses a plug-and-play Y-harness off the mirror/rain sensor power, so no need to run wires down to the OBD port. If anyone's ever unsure about fitment, just drop a photo of your mirror housing and we can double-check it.   Appreciate the detailed feedback on the install! On the windshield glare—we actually took feedback like yours and developed a dedicated CPL (polarizer) filter to cut down dash reflections on sunny days. If you're still running the cam, shoot me a DM. I'd be happy to send a CPL filter over for you to test out—no charge.

      There are no stickers in your glovebox?

      Yes, every time the developer updates his code, you must recompile. I will private message you with the latest because it changes pretty much with every version.

      Transmission Temperature Hitting 220s

      By Grumpy Bear · Posted

      After I wrote that reply I went for a ride. 85 F out. So trans started at 85 F and it shifted the same as it did an hour latter at 168 F. I've never actually recorded the to cold to shift point but it is under 32 F before they start hanging on to a lower gear or leaving the converter unlocked. Both intended to heat fluid.    Yes, brake or bake. Absolutely.      Your welcome. True research ended decades ago. Field trials are still in play.    There is a thing called oxidation onset temperature. This is the heat related oxidation not the O2 exposure kind. For mineral oil that starts at 140 F. So what happens after 140 F? Each 20 F cuts fluid life in half! Does using a Full Synthetic improve that? Yes! By how much? Depends on the base oil type and a few other factors. But enough to notice. Some esters are even higher. There are even synergies between types the will raise it higher than any one component is alone.    Then there is "Hindered" oils. Antioxidant additives. Hindered Polyol Esters can sit at 500 F for years in a turbine.   When a blender brags his oil will 'take 500 F" in service he doesn't specify for how long. Water will dance on a 500 F hot plate for several seconds. @newdude put up a chart showing the relationship between fluid temperature and it's life in an automatic transmission. Here's a version of that chart for Group III based oils. These temperatures are those in the pan as observed as 'normal'. that is you drive as you do for as long as you do under what load you ask of it and whatever that temperature is this graph applies to. Flash temperatures of a few minutes isn't what his means.    Note that fluids held at a constant 240 F have a service life of only 20K miles. 220 F explains the factory exchange limit, eh? My equipment I keep under 180 F and I'm good if the cooler will hold it as low as 140 F. But that's me.
